That's true. On the other hand, with the recordings I make using over the

Re: [Sursound] Suitable headphones for monitoring binaural compositions

2020-06-19 Thread Hector Centeno

I'm wondering if it is the case that if the ambisonic recording is made
with in-ear microphones then earbuds would make more sense, and if it's
done with microphones outside the ear (clipped on the sides of the head or
above the ear) then over-the-ear headphones would work. I record using
microphones over the ear and I find that playback using closed back
over-the-ear headphones works the best.

Re: [Sursound] Ambisonic Audio - Interactive Installation

2019-10-05 Thread Hector Centeno

I wonder if when talking about IMU's they should call it something
different, like "9 degrees of measurement" or "9 degrees of sensing" since
it's not freedom related to spatial movement. This particularly now that
spatial tracking is being used more prominently in consumer technology.

Hi Jack,

Yes, I saw those Bose but inertial sensors won't work for precise tracking.
I've done a lot of arkit/arcore with phones and tablets and it works great
but I don't want to be looking through a screen with a 2D representation of
the world while experiencing a sound only environment (unless you strap the
device to headphones with the camera facing forward, but that would be not
very convenient).

Cheers,

Re: [Sursound] Ambisonic Audio - Interactive Installation

2019-09-30 Thread Hector Centeno

I've been wanting to create work in this way for a while now (6DOF
audio-only augmented reality). This audio augmentation is what I found
appealing when I tried the Magic Leap AR headset for the first time since
it's very well implemented there (as opposed to the disappointing visual
quality). I wish someone will soon produce headphones with 6DOF tracking
(will require cameras to perform SLAM). In the meantime, I'm also waiting
for Intel to add Android support to their RealSense Tracking Camera T265 [
https://www.intelrealsense.com/tracking-camera-t265 ] which they claim is
on the works. This would allow strapping one of those sensors to a pair of

Thnak you very much Fons. I appreciate the explanation, it's very helpful
(It's also hard to find comprehensive literature about it). It would be
great to see those Python scripts, thank you for offering to send them.

[Sursound] Looking for virtual mic equations for 2nd order

2019-04-07 Thread Hector Centeno

Hello,

As quoted below, some time ago Fons kindly provided the equations to
extract virtual microphone signals from an ambisonic 1st order soundfield.
I was wondering, is there a set of available and known formulas to extract
virtual microphones from 2nd order recordings, taking advantage of the
higher spatial resolution? Does it make sense or the formula applies the
same only utilizing the 1st order part of it? I've seen some plugins doing
spherical processing to achieve this but that's an area I'm not familiar
with.

Thanks!

Hector

Re: [Sursound] Open HeadTracking Initiative OHTI - Release announcement

2018-05-18 Thread Hector Centeno

This is great Bo-Erik! I will definitively look into adding support to
AmbiExplorer for this tracker. I found a couple of sources online where to
buy the components but I was wondering if there's any particular breakout
boards for those ICs that you would recommend (both for the F52832 BT/SoC
and the BNO055 IMU). I would like to also look into designing a 3D
printable enclosure for it.

Cheers!

Hello Fons,

Thank you for your reply. Those conditions are easy to fulfill and I have
no problem sticking to them or any other that facilitate access to the
software.

 The source code you found is the latest. There hasn't been any updates
since then (I'm planning to work on it soon). As for hosting the APK
outside of Google Play, I can definitely do that. I'll put it on my
website, unless someone has a suggestion for a centralized repository that

source to GitHub so it's easier to track.

Cheers and thanks again.

Hi Bearcat,

Thank you for your kind words. I would like to add OctoMic support to the
TetraFile Android app, and I already had thought about it. It all depends
on the source code of the OctoMic version (octofile and octoproc) not
having any licensing restrictions. Fons mentioned that the software's
source will be available only to OctoMic buyers so I'm not sure if that
implies it won't be open source.

Cheers,

Hi Richard,

Thank you for your comments. I agree that it's needed to create awareness
of what Ambisonics is, which is why I included a short explanation and
links to resources in the app's description (I can't add more due to word
count limitations).

Regarding your UHJ question, I'm guessing it's a wording issue. Would
"transcodes to stereo UHJ" or "encodes B-Format to stereo UHJ" make more
sense?

Thanks again!

[Sursound] Upcoming update to AmbiExplorer

2018-04-19 Thread Hector Centeno

Hello,

After a long while, I've decided it is finally time to update my Android
app AmbiExplorer [
https://play.google.com/store/apps/details?id=net.hcenteno.ambiexplorer ].
I'm developing it on my spare time but I'm hoping to include at least these
new features:

- Add HOA playback, up to 3rd order using Google's Resonance decoder (for
now, later will try to add a variety of HRTF selections)
- Include Google's Resonance decoder as an option for FOA playback in
addition to the current HRTF sets
- Support both FuMa and AmbiX formats
- Possibly support TBA (Facebook 360 Audio)
- Support loading custom HRTFs (I also want to look into possibly adding
SOFA support)
- I've also considered adding a VR mode where the user would be placed in a
visually neutral space (dimly lit) as an alternative to head-tracked
headphones (this might also elicit a more focused listening attitude), and
possibly add the option of assigning 360 panoramas to audio files to be
displayed during playback.

These updates will be released in stages during this year but the first 3
are already on their way and hopefully will be released soon.

If anyone has any feedback about these updates or would like to suggest any
other features or changes please let me know!

Best regards,

Hector Centeno

[Sursound] Waves NX head tracker and third party applications

2017-11-06 Thread Hector Centeno

Hello,

I got a Waves NX Head Tracker [
https://www.waves.com/hardware/nx-head-tracker ] and I was wondering if
anyone here has managed to use the Bluetooth transmitted data for other
applications than the Waves ones? From what I found seems like the data
transmitted is encoded but I just wanted to double check in case someone
has found something different. I find both the Waves VST plugin and their
mobile app a bit inferior in sound quality, particularly the mobile app, so
I was wondering if I could manage to use the tracker with other
applications.

Cheers!

Hector

Re: [Sursound] AmbiExplorer for Andriod version 2.1 out

2015-03-08 Thread Hector Centeno

Hello Brian,

Thank you for suggesting using SOFA and sorry for the very delayed reply.
It makes sense and I will look into it. I'm using Csound as the audio
engine and the convolution opcode expects wav or aiff files (it uses
libsndfile) so it won't work out of the box. I think it would be great to
have a SOFAlizer opcode in Csound, I'll probably look into programming one.

Best,

Hector

Hello,

I just would like to share that I just posted a new version of
AmbiExplorer to GooglePlay and it should be live within a few hours.

The only change is that I switched it to use the optimized CIPIC HRTFs
from the Ambisonic Toolkit [ http://www.ambisonictoolkit.net/ ]
instead of the LISTEN sets. This means much improved ambisonic to
binaural
transcoding.

Big thanks to Joseph Anderson for his great work and for sharing it.

Happy New Year!

Re: [Sursound] AmbiExplorer for Andriod version 2.1 out

2015-01-16 Thread Hector Centeno

Hi Umashankar,
Sorry for the delayed reply. Any tablet or phone with Android 4.1 and up
and with a CPU of at least 1GHz should work. I recommend that if you are
going for a tablet to get something like the Nexus 7 (2013 model) or Nexus
9. If you are aiming at a phone, a Nexus 5 or 6 should work fine or any
Galaxy S4 and up. In the future I might integrate alternative decoding
techniques that might require a much powerful device so I would recommend
to get something newer.

Best,

Hector

[Sursound] AmbiExplorer version 2 video

2014-08-06 Thread Hector Centeno

Hello,

I just would like to share here with the community the new features
COMING SOON in version 2.0 of AmbiExplorer.

A walkthrough video is available here: http://youtu.be/gOsfo8or_0E

Please, feel free to make any comments, suggestions or requests in the
list or to my personal email. I'm planning on making the update
available within the next two weeks but I'm willing to delay it if
there are any requests that I think could be implemented easily.

My interest as a sound artist has been very influenced by the
practices of field recording, soundscape based sound art and acoustic
ecology. This is the reason why part of the new features are library
management and library import/export (online/offline) and geotagging
that would allow others to share location based ambisonic sound art
work or field recordings (the exported .ambxp file is a simple CSV
file with a structure described in the help section of the app). The
other major features are Bluetooth head-tracking, HRTF selection from
the LISTEN database and improved UHJ to binaural decoding. More
details below:

NEW FEATURES

- First run user interface tutorial
- New library system for importing 4 channel, dual stereo or UHJ files
- Select an HRTF for binaural decoding from the full IRCAM LISTEN database
- Connection to an external Bluetooth head-tracker with communication
protocol based on the Razor AHRS project:
https://github.com/ptrbrtz/razor-9dof-ahrs/wiki/Tutorial
- Library item geolocation and Map view
- Library item description/title editable
- Create location placeholders using GPS (good for tracking locations
during field recordings) or by long-pressing on the Map View. The
placeholders can later be assigned to ambisonic files
- Playback using automatic location based triggering that also works
while the app is running in the background (with status bar
notification)
- Import and Export libraries as CSV files with extension .ambxp. The
exported libraries include the geolocation and title data.
- Import libraries from internet sources
- Greatly iImproved UHJ to binaural decoding
- Decode B-Format to stereo UHJ
- Improved internal sensors stability
- Several bug fixes and interface improvements

The source for the TetraFile Android app is now available here:
http://www.hcenteno.net/software/TetraFile_Android_SRC.zip

It contains 3 Eclipse projects: the TetraFile executable, the Java
Android frontend and the fft library used by the executable.

Not included is the source for libsndfile (required by the
executable), which can be found at:
https://bitbucket.org/kunstmusik/libsndfile-android.

I don't think that the changes I made to Tetrafile are worth for Fons
to include in his main code since they are just simple log messages
that are used by the frontend to display the processing progress.

Best,

Hector

 it doesn't need to be cleaned, really, but you need to get that source out
 asap. until you do, you are violating the license, which means you can't
 legally distribute tetrafile for android. or, if your modifications are
 small and self-contained, maybe just feed them back to fons and ask if he's
 interested in adding them to his repo.


 Tetrafile depends on libsndfile which would have to be compiled
 separately for Android but I guess I can include the precompiled
 library with the Tetrafile NDK project. It took a bit of work to
 finally get libsndfile working on Android but Steven Yi (a well known
 Csound contributor) and I managed to get it done. The code for
 libsndfile is here:
 https://bitbucket.org/kunstmusik/libsndfile-android

 As for AmbiExplorer, I didn't use any GPL code in it that would force
 me to release the source code and for now I would like to keep it
 closed. I will consider to release it in the near future.


 oh, sure. i did not mean to imply otherwise, and i respect your choice of
 license.

 otoh, i don't think that open-sourcing it would necessarily reduce your
 income from the app - installing something from google play for a few euros
 is just sooo convenient that i'd be very much surprised if more than 1% of
 your prospective customers would rather set up their own build
 environment... (i know i wouldn't - many other open-source apps are marketed
 via google play for reasonable amounts of money, and i always like to
 support people who donate their code to the public.)

 Not really. They declare themselves that the Apache license is compatible
 with the GPL. Not all licences are.

 Cynics call the GPL a polluting licence as it requires all the code,
 including that from elsewhere, to be under either the GPL or a compatible
 one - at least, one that is not more restrictive than the GPL itself. So,
 for example, as I understand it, GPL code can be freely combined with code
 that is fully public domain  (free and without any restrictions at all,
 including closed commercial use etc; one example is the Synthesis Toolkit -
 STK, and any amount of code under the BSD licence, which is essentially a
 standard disclaimer of responsibility). So one thing you cannot do is mix
 GPL and closed source and publish only the GPL parts. The point of the GPL
 is not simply to licence individual source files, it is more to ensure any
 user can build their own modified version of the application (which must
 then also be published under the same terms).


 ..

 See above. If you argument above is correct, things get quite difficult,
 because typical Linux toolkit licenses are GPL. (So and according to the
 argument above, you can't separate your code into GPLed and other
 license/closed sections. Even if you try hard to do so.)


 Nope, indeed you can't. There is some flexibility regarding libraries (which
 could be under the LGPL; but under the strict proviso that the user can
 relink with a different version of the LGPL library. Some of that depends in
 the LGPL library being dynamically linked, so the user can simply relink the
 binary with it. On the iPhone no dynamic libraries are allowed, so
 everything has to be statically linked, which means in turn that even if it
 is an LGPL library, everything must be made available. If Tetrafile is GPL,
 it cannot be treated as LGPL, and all the sources of any application using
 it needs to be available under that licence.


 Copyright holders of GPLed software can of course offer alternative non-free
 licences if they choosee to. The classic example is FFTW, which is free
 under the GPL, but is also licensed commercially (e.g. for Matlab). I don't
 think that licence is particularly cheap though!

Re: [Sursound] AmbiExplorer

2014-01-24 Thread Hector Centeno

Hi Michael,

I'm sorry that AmbiExplorer didn't work on your daughter's device. If
anyone experiences problems with the app please feel free to email me
directly. I'm more than happy to try to figure out what's going wrong. A
downside of Android development is the overwhelming variety of devices and
making apps work on all of them.

On a recent update I added the option of sending bug reports via email for
non-crashing issues like no sound being heard. The best way of doing it is
to close the app by pressing the back button or closing it in the app
switcher. Reopen the app, load a sound file and hit play. If the time
counter doesn't move, press the settings button on the top-right corner and
select bug report at the bottom; follow the instructions for sending a
log report via email. If after hitting play the app becomes unresponsive
then wait for the system warning and send a report.

Best regards,

Hector

Hi Jörn,

Did the reset button return the head or mics to face forward with the
sensors off? The reset button, for now, should only works for when the
sensors are off and the head/mics are being moved manually. Which means
that yes, for now we will face north :-)

In an upcoming update I'll make the reset button work with the sensors to
reset the soundfield front to be in the same direction as the device when
pressed.

[Sursound] Upcoming Android apps ambisonic related

2013-12-10 Thread Hector Centeno

Hello all,

I just wanted to share with this list information about two Android
apps I've been working on and that I will release soon. I made them
because I thought it would be great to be able to listen to ambisonic
recordings in a portable way without the need of a full size computer.

The first app is called AmbiExplorer and it's a first order decoder to
stereo, with the option of choosing binaural or virtual microphones.
You can peform soundfield rotation and microphone polar patten
selection. It will also work with the device's orientation sensors so
you could attach your device to headphones and have head-tracked
binaural listening.

The second app is called TetraFile and it's a port of the offline
command line utility part of Fons'  TetraProc. I made this so I could
connect my portable recorder (in card reader mode) directly to my
phone via USB OTG, transfer the A-format files and do a conversion to
B-format and listen using AmbiExplorer. It will read your tetrafile
calibration files from your phone's storage.

More info and a video demo are available here: http://hcenteno.net/software.html

Any comments are welcome.

2013-12-10 Thread Hector Centeno

Hello Bo-Erik!

Yes, I hope to have them released before Christmas.

Making a VST out of the AmbiExplorer app would mean reprogramming most
of it because even though Android is built on top of Linux, apps use
lots of Android system specific frameworks. There's also the fact that
it's mostly programmed in Java (not sure if there's an easy way of
making audio plugins in Java) and for a plugin I would more likely
want to use C++. I might anyways consider to  work on it in the near
future, though! Some of the work I've done for this app would
definitively help towards programming a VST version.

Cheers,

Hector

Re: [Sursound] Hector bird recording - SoundCloud

2013-11-23 Thread Hector Centeno

Hello!

Yes, I gave those recordings to Umashankar before I got the microphone
calibrated. I just uploaded a B-format version converted using
Tetraproc and the preset file that Fons made for me after I gave him
my IR measurements. It's not exactly the same fragment but comes from
the same group of recordings. Those birds make indeed very strange
sounds, they are called Urracas in Mexico, were the recording was
done. This is obviously not a pure nature recording since it was done
in the backyard of a house in the city. I placed the mic right under
the tree where the birds were perching.

I'll try to get the music recording processed too by tomorrow.

[Sursound] Looking for virtual mic equations

2013-07-19 Thread Hector Centeno

Hi,

I'm trying to implement virtual microphones derived from first order
ambisonic soundfields using Csound. I was wondering if anyone had any
resources to share with equations that would allow me to achieve this,
specifying azimuth, elevation and directivity of the mic. I've been
analyzing Fons' code for Tetraproc (the Virtmic class) but I'm having
difficulties understanding some parts of it (but I'll keep trying). I found
the paper Has Ambisonics Come of Age? by Bruce Wiggins wich contains
equations for doing this but it seems that it only takes azimuth angle in
consideration.

Thanks in advance,

Hector

Re: [Sursound] Ambisonic-Binaural piece using Brahma mic (was Re: Great responses to my post--thanks!)

2012-01-11 Thread Hector Centeno

Hi Michael,

Yes, I'm aware of that and it's a very nice feature. I also use the VST plugin 
VVMic for ambisonic to stereo conversion which I'm assuming does something 
similar to the stereo output in Tetraproc (virtual mics with adjustable 
polarity and orientation). In this case, of course, I'm attempting full 
periphonic decode into a binaural sound field.

Cheers,

Hector

 You are almost certainly aware that TetraProc offers two channel

 Fons (some years ago) was quite self-deprecaing about the
 Xtalk option. But I appreciated it.
 
 I certainly use them with success for 'stereo', but have little

Hello Eric,

Very interesting post. I was a bit intrigued by what you had to say regarding 
binaural recordings and the lack of sense of space. Reproducing a sense of 
space is something that has interested me a lot as a sound artist and I've been 
experimenting with building different types of binaural mics. Here is an 
example recording I made:

http://soundcloud.com/hcenteno/kids-running-in-the-wychwood-barns

If I close my eyes I can really feel the space and the kids running in front of 
me, and not inside my head, but I wonder how would other people perceive it 
(I'm very familiar with the space where this was recorded so I wonder if that 
influences my perception). I've been also experimenting with recordings made 
with a first order mic decoded to stereo binaural with head tracking and indeed 
the sense of space works quite well, although I have to say that not as defined 
as the stereo binaural recordings (which might be a flaw on my process which 
I'm still refining).

Cheers,

Hector

Re: [Sursound] problem with jconvolver on osx

2011-10-11 Thread Hector Centeno

Hello,

I've been looking into an alternative and came across this:

http://sememu.sourceforge.net/

I'm not a C expert so not sure if this could work. I tried to build
zita-convolver using this but got errors:

./sememu.c:342: warning: ‘MPSignalSemaphore’ is deprecated (declared

The warning is because I'm on Lion and MPSignalSemaphore has been

zita-convolver in C++ so I wonder if that's the issue.

Cheers,

Hector

 The reason for this is the crippled implementation of POSIX
 semaphores (sem_t) on OSX:

 1. Only named semaphores (i.e. having a file system name)
   are available.

 2. The sem_init() function does not work.

 3. The sem_getvalue() function does not work.


 While (1) is not a final showstopper and there are (clumsy)
 solutions to work around it, (2) and (3) are. Future versions
 of the library will even use more semaphores, so this problem
 is not going away.

 The only solution is that some OSX expert/hacker writes a
 complete, correct and efficient version of sem_t, which will
 probably be based on the system's MACH semaphores. It should
 not be difficult at all for someone with the right background.

Exactly what I've been exploring using ambisonic recordings from a

 VR93 confence from that year but I don't have my copy of the proceedings

 tracking drove a rotate/tilt algorithme that fed a decoder to virtual
 speakers the signals from which were convolved with fixed hrtf's
 corresponding to the speakers' positions that were fixed wrt the head, mixed
 together and fed to the headphones.

Re: [Sursound] Brahma mic users?

2011-05-18 Thread Hector Centeno

Hello Michael and Umashankar,

Yes, I've been doing some recordings with it and I'm liking the
results. Later today I can upload some of them and post the links here
for you to listen. Do you prefer the raw A-format or the B-format
conversion? For the B-Format conversion I've been using TetraProc
without any calibration files and using the default theoretical mic
preset. I can also upload binaural versions of those recordings.

I did try to match the levels of the four capsules by recording twice
a test signal, first with the front and then with the back side of
the mic facing the speaker. Then I matched the gains of all four
capsules using this recorded test signals and applied the same gain
compensations to the recordings. This is probably not the best
procedure but it seemed to improve the results, particularly the
general balance of the soundfield.

I recently did some IR measurements and sent them to Fons who is
kindly helping me making the calibration files for TetraProc. Once I
get those I can later upload the same recordings but now calibrated
for comparison.

Cheers,

Hector

one member of this group, hector centano, has a brahma and i heard nice

the first thing i must point out if you want to buy a brahma is you will have

this. (hector and i have both used them uncalibrated, with a kind of best fit

Hi,

I've been on this list a while and not posted anything, mainly because
I find I have little to add to the usually on-topic and interesting
exchanges that go on here. However, I'm soon to be in the market for
an A-format/soundfield microphone. My budget is limited, so this means
either the Tetramic or Brahma mic/kit appear to be my only options.
While I can find plenty of testimony regarding the Tetramic's
strengths and weaknesses, there seems to have been little or no
discussion of Umashankar's Brahma. Have any list member's had
experience with this mic? In terms of cost, it seems like a very
attractive package to begin recording ambisonic material.

thanks

Michael Noble

ps. I realize Umashankar, you are a list member. I hope you are not
offended that I should seek third party input before inquiring to you
directly about your products.

 The mic was close to the edge of the stage with the two performers in front,

Re: [Sursound] HARPEX-B Plus First Order Mic vs. Third Order

2011-04-06 Thread Hector Centeno

Hello,

Not related to a comparison with a third order mic but related to
directional cues: I did a quick check using the demo plugin decoding
some tetrahedral mic recordings to binaural. I loaded it into a
Max/MSP patch and did A-B comparisons between two combos consisting of
Tetraproc-Harpex and Tetraproc-Ambdec-SPAT (SPAT for the binaural
virtual speakers). To my ears, this comparison revealed that
directionality was much precise and clear with the TAS combo than with
Harpex. This was particularly noticeable with a recording of birds
singing from tree branches located above the mic. With Harpex some of
the bird calls would jump around spatially as the spectral content of
the call changed whereas with TAS it remained focused and well
localized within a discernible location. I haven't done a test
decoding over speakers so I'm not sure if this would be only related
to binaural decoding.

 One claim he's making is that his parametric decoding method allows a

 cues that are equal to or better that what's available from a third-order
 soundfield microphone.  Also, presumably the sweet spot is comparable

 If you've been using the HARPEX-B player or plug-in, do you think the claims

Congratulations! I was looking forward to this release after trying
the online conversion. Any chance there will be a non-commercial price
(I'm a sound artist, not a commercial producer)? It feels a bit unfair
to me that something like this gets focused only on main stream
commercial production when it could be a great tool for artists.
Paying for this plugin would be way more than what I paid for my DAW

pricing Reaper style where you pay according to how much your yearly
revenue is? Just a thought.

 5. counter-productively expensive (compared to Reaper or Plogue)

 As you all know, the marginal cost of software is close to zero, everything 
 is in the development. So, when you compare a specialized product to a 
 mass-market product, it makes no logical sense to compare their feature set 
 without at the same time dividing by the potential sales numbers. It should 
 be noted that I am not paid by anyone to do this work, so the business model 
 here is that the users must pay for all of the development. Since this 
 plugin in practice requires the use of a soundfield-type microphone, which 
 is not really a mass-market product, I don't expect to recoup any reasonable 
 wage for the time spent on it. From a customer's point of view, the price 
 should be considered in relation to the cost of all the other gear involved 
 - the microphone, recorder, computer, daw etc and the relative value added 
 by the plugin. I think it's a good deal, but don't expect much sympathy from 
 academia.

 I don't know enough regarding software sales and pricing strategies to have 
 any clear opinion on what's the right price to eventually cover the 
 development costs. The reasoning above seems sensible, but is assuming that 
 the same person/organization owns and use the mic, recording hardware and 
 equipment/software for playback. That might not always be the case.

 I'm working at BEK, a media lab for artists in Bergen (NO). We have a 
 SoundField mic and it's getting increasingly popular among local artists. 
 Depending on the project they often get to borrow it and the hard disc 
 recorder for free (or almost free). For many of them it will be interesting 
 to be able to use Harpex for decoding later on. While BEK itself can and 
 probably will get a plug-in license, I'm less sure how many of the artists we 
 work with that will be able to afford it. On the other hand it might well be 
 that they can do decoding when required at the BEK studio, and thus won't 
 depend on having their own license.

 Just my 5 cents. I've set aside a full day at the study next week to try it 
 out. Natasha Barrett has been very enthusiastic about Harpex, so I'm looking 
 forward to playing with it.

[Sursound] ambdec 0.4.4 package for Mac OS X 10.6 available

2011-03-24 Thread Hector Centeno

Hello,

As I mentioned earlier, I was working on packaging ambdec for Mac OS
X. I've got it done and tested but for now it will only work on 10.6
(Snow Leopard). As soon as I get to compile it for 32 bits I'll post
another installer for Mac OS 10.5.

The installer will put ambdec in /usr/local/bin, libraries in
/usr/local/lib (as the original installer would do) and the presets in
/usr/local/share/ambdec_presets. I also made a launcher that is
installed in your Applications folder together with the presets (all
in a folder named ambdec) for those who don't want to use a terminal.
If you rather start ambdec from a terminal then during the
installation you can select to customize the install and deselect the
launcher.

You should have X11 installed (usually there by default, check in your
/Applications/Utilities folder) and also JacOSX (the dual 32/64 bits
version for Mac OS 10.6). Jack should be started before running ambdec
and X11 will start automatically when you start ambdec.

The only know issue using the launcher is that the system doesn't
detect that ambdec has started so the ambdec icon won't stay in the
dock (it will disappear after bouncing for a little while, without
affecting ambdec), I'll try to fix this for a second version of the
installer.

You can download the installer here:
http://www.hcenteno.net/software/ambdec_0.4.4.pkg

Please let me know of any issues with this installer. I hope this is
helpful to others.

 it outperforms other decoders i've heard, and it's quite easy to use. there

 Hello Darren,

 I second jörn, ambdec is the way to go. I've just recently tested it
 against ambidecode~ and IRCAM's spat.decoder~ object and I found
 ambdec to produce a much better result overall. I've compiled it under
 Mac OSX 10.6.6 but I remember having to tweak something in the make
 file for ambdec or maybe one of the needed libraries. I could try to
 build a package later today or tomorrow.

 Darren here,

 thanks for all your help, much appreciated.

 I have consulted my friends and we think maybe a 8 speaker setup is best
 for our audience we are going to perform from 40 to 300 people

 We are looking at now using max/MSP with 8 speakers and using routing of
 4 sends in different panning postions from 'LIVE' to max/MSP.

 Does any one have a good patch for max/MSP or is the help file
 ambiencode~ and ambidecode~ enough taken from - icst website 
 Ambisonics Externals for MaxMSP  and would this be best to use.

 if you're using mac os, i'd recommend you try fons' ambdec decoder. not too
 hard to build for osx, and maybe someone here has already created a package
 they might be willing to share?

 it outperforms other decoders i've heard, and it's quite easy to use. there
 is a preset for third-order octagons, and all you need to change are the
 speaker distances. you really want to use third-order panning.

 best,

 jörn

Re: [Sursound] HRTF Database

Hello,

I was wondering if anyone knows if these MATLAB HRTF files can be
found as IR audio files somewhere. I won't be buying MATLAB and I
would like to try them using a convolution plugin or a MAX/Msp patch.

 CIPIC HRTF Database

 The CIPIC HRTF Database is a public-domain database of
 high-spatial-resolution HRTF measurements for 45 different subjects,
 including the KEMAR mannequin with both small and large pinnae.

 The database includes 2,500 measurements of head-related impulse responses
 for each subject. These standard measurements were recorded at 25
 different interaural-polar azimuths and 50 different interaural-polar
 elevations. Additional special measurements of the KEMAR manikin were made
 for the frontal and horizontal planes. In addition, the database includes
 anthropometric measurements for use in HRTF scaling studies, technical
 documentation, and a utility program for displaying and inspecting the data.
 Accessing the data requires MATLAB 5x or greater. Additional details are
 given in the following paper:

Re: [Sursound] cross-talk cancellation used in binaural sound

2011-03-14 Thread Hector Centeno

Hello,

I'm one of those folks, although I hope I'm doing it well. I've been
doing some initial tests for an installation that uses ambisonic
recordings done with a tetrahedral mic. The B-format signal is then
decoded and played over headphones using virtual speakers panned
binaurally. I'm also adding a head-tracking device consisting of an
iPod Touch running an app that sends the gyroscope orientation to a
Max/MSP patch for altering the pitch and yaw of the B-format signal
before it's decoded. The localization is far from perfect and not as
accurate as  with pure binaural recordings but I'm very happy with the
results. Also I have yet to further calibrate the mic which will very
likely improve the image.

Cheers,

Hector

Re: [LAD] [LAU] JackMixDesk-0.3-r2 Release

Hi,

I just installed Jackmixdesk 0.3 from the Packman repository under
OpenSuse 11.1. When I move the sliders they give sudden jumps up and
down. Also I was wondering what is the purpose of having the volume
sliders to grow when moved horizontally?

Cheers,

2009/6/4 Ulrich Lorenz Schlüter audio-mobs...@gmx.de:
 I removed some bugs that came up till now and released version 0.3 of
 JackMixDesk formerly known as jackminimix.

 Get it from http://sourceforge.net/projects/jackmixdesk/

 Jackmixdesk is a client/server mixer application with a user defined
 number of channels, pre and post fader sends. It has LASH support an OSC
 control interface and a XML config file. There is also a gui made with
 GTK+. It uses less resources than it's ancestor jackminimix.

 I'll soon start further development.

Yes, I do have that code in pd.tk which I had already hacked before in

the 8 has to be changed by 7 like this:

set sizelist 5 6 7 9 10 12 14 16 19 25

For some reason in general the fonts in Fedora look bigger. After

ah! I found the source of the problem. Googling for the font size
issue in Fedora I found that it seems that Gnome in Fedora 10 has
problems auto-detecting the right DPI for the display. In the Font
section of the Appearance Preferences, clicking on Details shows a
configuration window where the resolution in DPI can be set. I changed
that to 96 and the fonts work fine in PD with the original values in
Pd-0.41.4-extended-rc3.

 Thanks hc,

 How do I achieve that? What is the order for loading things in PD?

 the order of loading is the order of occurence.
 first, all libraries in your pdsettings are loaded in the order they
 appear therein.
 then all libraries specified via the cmdline are loaded (in the order
 you specified them).
 finally, libraries are loaded within patches: 1st libs specified with
 [declare] (and probably [import]) are loaded; lastly the remaining
 libraries are loaded whenever an object of their name occurs first.


 Sorry if I'm asking for something too obvious, I haven't used PD that
 much. In my patch [vbap] is inside a sub-patch and
 [define_loudspeakers] in another sub-patch and both within the main
 patch. I tried putting the second inside the first but that didn't
 help.



 so:
 if you haven't loaded [vbap] yet, make sure that an object [vbap] is
 _created_ before [define_loudspeakers].
 (just Ctrl-X-Ctrl-Z the sub-patch containing [define_loudspeakers]
 should be sufficient)

 having said all that: your problem seems to be that
 [define_loudspeakers] cannot read a file named ls_setup, which
 according to its name might define the actual rigging information for
 your loudspeaker setup.
 since the object itself loads fine, there seems to be no problem with
 needing [vbap] at all.
 your initial assumption that you have to create a file ls_setup seems
 to be quite right.

 the short answer:
  because you are doing something wrong (and everything on the system
 actually works as it is supposed to)

 the long answer:

 i really don't know. i never used vbap.

 however, i now had a short look:

 there is no mention of ls_setup anywhere in the sources.
 i don't get an error if i instantiate either the help-patches (apart
 from [matrix~] being no longer part of zexy but rather of iemmatrix and
 renamed to [mtx_*~] (or [mtx_mul~] if you have problems with libraries))

 you must be generating the error somewhere else.
 try to isolate the object that complains and let us know what you have
 found.
 (hans might well be right with his assumption that you were failing to
 instantiate an object (ls_setup could be the setup-function of an
 object [ls]); the way you described the problem does not give any hints
 in this direction).

[PD] PD sound quality question

2009-05-23 Thread Hector Centeno

Hello,

I'm in the process of learning more about PD so I've been checking
some of the patches that are part of Johannes Kreidler's excellent
tutorial Programming Electronic Music in Pd (
http://www.pd-tutorial.com/ ). Today I was playing a bit with the
sampler-big.pd which is a sound sampler with adjustable speed and
start/end points. I noticed that as I made playback speed slower I
started to hear quite noticeable aliasing. The patch uses [tabread4~]
for reading the sound array. So my questions are: is this aliasing a
particular problem of my system or is this an expected result? Is
there anyway of avoiding it? I could post the patch here if needed.


Cheers,

Hector

 track all the changes in the Pd version, and incorporate them where they
 made sense.  But basically, I ended up porting the Max/MSP 1.0.3 sources
 from scratch.

 There are some minor differences between the Max/MSP version and this Pd
 port:

 - a fifth inlet/outlet was added for 'gain' but since this provided no
 functionality that could not be handled in Pd using a [*~], I did not
 include that in the Pd port.

 - the Max/MSP version only has arguments for the 2nd and 3rd inlets
 (azimuth
 and elevation), I added an argument for the fourth inlet (spread).

 Its in the nightly Pd-extended builds, or in SVN:

Re: [PD] call for vbap testing in Pd-extended or SVN

2009-05-21 Thread Hector Centeno

Hello,

I just built pd-extended from SVN and vbap fails to work since it's
looking for a file named ls_setup which is not installed. Do I have to
create such file? I used vbap before and I don't remember having to
deal with this so I guess is part of the new changes.

Cheers,

Hector

 I finally updated vbap to Villa Pulkki's most recent version.  It was 0.99
 now its 1.0.3.  The Pd code ended up being too different and I didn't have
 the original Max version that was ported to Pd to compare, so I tried to
 track all the changes in the Pd version, and incorporate them where they
 made sense.  But basically, I ended up porting the Max/MSP 1.0.3 sources
 from scratch.

 There are some minor differences between the Max/MSP version and this Pd
 port:

 - a fifth inlet/outlet was added for 'gain' but since this provided no
 functionality that could not be handled in Pd using a [*~], I did not
 include that in the Pd port.

 - the Max/MSP version only has arguments for the 2nd and 3rd inlets (azimuth
 and elevation), I added an argument for the fourth inlet (spread).

 Its in the nightly Pd-extended builds, or in SVN:

Re: [PD] Pd-extended 0.41.4 release candidate 1

2009-05-15 Thread Hector Centeno

Thanks to all for your replies,

I found that page about font size and Tcl/Tk 8.5 last night and
started looking for some 8.4 packages for OpenSuse but couldn't find
anything. OpenSuse 11.1 is the same as Fedora 10, they moved to 8.5
and there are no 8.4 packages (I remember Ubuntu being better for
providing older versions). I wonder if we could look into pd's code to
try to fix this with 8.5, any ideas where I could start looking?

Cheers,

Hector

 The pidip error is really just a warning.  I think you can set a font then
 it'll work.  Otherwise, check out the source files for the two text objects,
 you'll see the default location is:

OK, I got the font size fixed! If I change the foreach (at line 3944)
in pd.tk from:

foreach i {8 9 10 12 14 16 18 24 30 36} {

to:

foreach i {4 6 8 9 10 12 14 16 18 24} {

 I am guessing that you could do some font sizing like is in pd-devel 0.41.
  Check out pdtk_pd_startup in pd/src/u_main.tk.  There you can find the font

 You click on the point you want to delete and hit 'backspace'.

Re: Ubuntu Studio is looking for help.

Hello,

I've tried to join packaging efforts before (Ubuntu and Fedora) but
the whole administrative process seemed too slow and painful to me. I
often find some good audio applications missing in the Ubuntu repos or
some of them are not updated.  If I create a proper package of an
updated version (like some LADSPA plugins, Csound, PureData, etc)
would it take short time to be included in the public repos or would
it have to wait for the next Ubuntu release? Is it possible to help by
packaging something that has a maintainer assigned already but its not
being updated?

Cheers,

 can do more stuff if we have more people. Plus a few members are
 taking a massive load of work and it would be good to try making it
 lighter.

 Documentation has almost no help, so I would really appreciate if you join.

Re: Problem with Blender in Hardy

2008-05-04 Thread Hector Centeno

Hi Cory,


  I always recommend a from-disk install if you need Studio. Installing
  the metas from the repo is *not* Studio.

  -Cory \m/


What are then the differences between installing UbuntuStudio metas
over a Hardy install and installing straight from-disk (beside getting
less apps because of the slimming down of Studio)?

Thanks!

I've been searching the documentation and the web for the manual pages of
the, already deprecated, [matrix] and [matrix~] objects. I was wondering if
anyone could quickly tell me what are they for (matrix multiplication, I

Re: [64studio-devel] Backport of GNOME 2.18

2007-08-08 Thread Hector Centeno

Hello,

I just would like to share my personal opinion. I think to include a newer
version of Gnome in 64Studio can be a good idea. Not only by reading the new
features ( http://www.gnome.org/start/2.18/notes/en/ ) you can see what the
advantages would be, but also I'm pretty  sure there are plenty of bugs
fixes that might not be obvious by using it for a short time. Also the Linux
audio community around 64Stduio gets a chance to use the latest version and
to be at the same point in the development of Gnome where the Gnome devs
are, so there is a better possibility to help with bug feedback and feature
testing/suggesting.

Just my two cents.


Cheers!

Hector

Re: [64studio-devel] Some other packages

2007-07-22 Thread Hector Centeno


Hi Free,

Csound (the latest version) would be great. In fact I think a lot of the
packages available in Planet CCRMA would be nice to have in a Debian based
distro. CCRMA seems to be the only repository where you can get most of the
audio apps particularly those that are useful for more academic style of
computer music. It could be nice that 64Studio and UbuntuStudio favored the
inclusion of these kind of apps in their latest versions. In fact, it would
be nice if all that is available in the CCRMA repository was available in
64Studio.

Cheers!

[PD] looking for good quality PV

2006-11-01 Thread Hector Centeno


Hello,

I was wondering if anyone knows of an external for good quality Phase
Vocoder analysis and re-synthesis. I've tried the fft example included
in PD and the quality is not really that good for extreme time
stretching (which I'm interested in doing). I've been using the PVOC
opcodes from Csound, which are of very good quality, but I would like
to know if there is anything available for PD with similar quality. I
know that I could modify the FFT example for making it sound better
but honestly I'm not that proficient in DSP.

Thank you!

Hector, si revisas el histórico de la lista (no se si ya se puede...
Pero si llevas un poquito de tiempo en la lista, digamos 8-12 meses), verás
que hay algún debate de ventajas y desventajas del Delegate, y qué hace
exactamente.

Si no puedes revisar los antiguos correos, intento enviártelos yo o
algo.

	Un saludo.

Solo para agradecer la ayuda, Xavi, gracias no tenia idea de la existencia
de Delegate, aunque aun no lo alcanzo a comprender del todo, según entiendo,
basicamente se trata de no perder el scope en el que opera la función (en
este caso el metodo) de esta forma la función sabe de la existencia de la
clase y sus variables, estoy en lo correcto ?

Tambien gracias a David tu idea tambien me ha hecho conocer otra cosa que no
sabia. Aun no entiendo bien esto de la oop y esta es mi primera clase.

Jose Tomas, gracias por el code, de momento me queda un poco corta pero esta
bastante bien ;) gracias

Saludos.

Re: [ASNativos] Violación de la seguridad Sandbox

2004-08-17 Thread Hector Centeno

JEJEJe, me has dado con la misma piedra, bien lo decian en FlashLA jejeje
Ok ya tenia información sobre el asunto, y ahora busque en la *lista de 
correo *y la verdad que no sirvio de nada, solo me hizo entrar en más 
dudas. Segun una contribución de Joseba la cosa esta así:

/In order to support local development and testing of Macromedia Flash
moviesby developers, movies accessed as local files (either on the end 
user's local disk or on LAN servers) have no sandbox limitations. 
This is consistent with the added caution users should always take 
when running any type of file locally./

Entonces por que demonios me manda el error cuando se supone que si 
estoy en local no deberia dar este tipo de problemas, tambien cabe la 
posibilidad de que como dice el mismo joseba, ua pelicula Flash se 
considera dentro del entorno protegido (lease Sandbox) cuando se accede 
a el mediante una llamada por HTTP, y como estoy trabajando en local 
(/http:localhost/) entonces en realidad sí estoy trabajando bajo 
SandBox, o me equivoco??. La cosa es que de cualquier manera no deberia 
dar este problema ya que todas las llamadas a archivos (los PHP y los 
XML) se hacen mediante la misma dirección.

Alguien tiene otra idea ??

Re: [ASNativos] Violación de la seguridad Sandbox

2004-08-17 Thread Hector Centeno

Esque eso es lo más extraño del caso, trabajando directamente en el IDE 
es donde saca el aviso de seguridad. Accedo de esta forma:
tengo un path global para accesar a todos los archivos, esto fue por que 
antes durante la elaboración estaba trabajando todo con bases de datos y 
la información de los XML los generaban unos PHP que sacan la info de la 
BD. Despues me entere que en el servidor (por ser gratuito :-[ ) me 
generaba los Xml con mucha basura,  por lo que genere XMLs estaticos, 
pero ahun así segui trabajando con la siguiente dirección (la cual 
despues iba a cambiar por el dominio publico)
_global.patht=http://localhost/siamoamici/;;

despues, donde saca el error este es cuando acceso al php que genera las 
imagenes pequeras, esto es:
image=patht+sample.php?ima=+pathActual+/+parent.childNodes[itm].attributes.nombre+.jpg;

que es donde saca el error.
Cuando accedo por el navegador 
(http://localhost/siamoamici/galeriaxml.swf) la cosa funciona bien, (me 
da algunos problemas pero creo eso es cosa de mi programación, aunque no 
estoy se seguro). y si entro por la ruta fisica 
(file:///C:/EasyPHP1-7/www/siamoamici/galeriaxml.swf) la galeria no más 
no va...

Sigo investigando, y haber si tu o alguien más sabe algo 
GRacias Xavi...

Re: [ASNativos] Referencias sobre componentes Flash MX 2004

2004-08-01 Thread Hector Centeno

Si de hecho si quieres sacarle un buen partido a la interacción cliente 
servidor es mejor que tu hagas el codigo, tienes mucho mayor control y 
puedes adecuarlo a tus necesidades especificas. En cuanto a que se gener 
el codigo no creo que sea posible ya que los componentes trabajan de 
forma, digamos encapsulada (componentes compilados) supongo que es por 
eso que no general AS sino todo lo controlan ellos. (aunque en algún 
lugar se debe guardar la configuración).

Carlos Terradillos Gutiérrez wrote:
Gracias Héctor,
parece un gran artículo y de momento responde a algunas de mis dudas  
más urgentes.

La conclusión que adivino (el inglés, lo adivino...) es que el 
sistema  de paneles para manejar los componentes es útil para 
desarrollo  sencillos pero que en cuanto se complica la cosa hay que 
actuar  directamente mediante as.

Vaya, un poco lo que sucede com Dreamweaver2004 y el sistema de 
acceso  a bbdd.

Lo que no acabo de entender es por qué las decisiones que se toman 
a  nivel de los paneles de los componentes no se presentan 
automáticamente  en el panel del editor de código. Sería un modo de 
aprender pero sobre  todo de meterle mano a los detalles que 
quisiéramos ¿no? (suponiendo  que el código fuera inteligible...).

Saludos.
