If so, does anyone have any example of its use beyond the help files available in Pd? I'm not able to work out how to use it. I have an ambisonic project in which i'm using cart2del_damp_2d to to simulate the early reflections of moving sources relative to a virtual listener in a virtual room - and ambi_encode to do 2nd order encoding of the scene. The scene is ultimately decoded by ambdec for a 2D speaker array via jack. Can iem_bin_ambi be used to produce a binaural mix of this - or am i right off track? Other suggestions? I've been playing around with cw_binaural~ as an alternative technique (sending it angle values from a GUI and cart2del_damp_2d and damping the signal with distance) - sounds great but I can only spatialise the direct signal and the 1st set of early reflections from cart2del_damp_2d (using another 4 instances of cw_binaural~) before the computer starts to pack it in. I'm hoping that iem_bin_ambi might be more efficient.

Re: [PD] Analog square wave?
* chris clepper cgclep...@gmail.com [2012-02-06 15:49]: In an analog synth the square wave has some distortion to it: the rise is not instantaneous and there is some overshoot of the peak too. Over the years this was minimized by using high slew rate amp circuits and the like so an old Moog pulse wave is less ideal in shape than a new one. For a digital square wave you would want to use band limiting to avoid alias artifacts which are quite severe for a square or sawtooth wave. As the frequency goes higher both of those waves will begin to look more like sine waves as the partials are filtered out. Pretty much every commercial digital synth and plugin uses anti-aliased waveforms. out of interest Chris, do they use wavetables (possible of different lengths for different octaves) or internal oversampling a la Millers example in the doc patches? best, P On Mon, Feb 6, 2012 at 8:31 AM, Pierre Massat pimas...@gmail.com wrote: Dear List, I need a square wave to use as an LFO in a ring mod patch.

Re: [PD] Making a Realtime Convolution External
Dear Seth,
Seth Nickell wrote:
Another question on similar lines...
Are the DSP calls liable to vary t_signal-s_n (block size) without
notification? 64 samples, apparently the default on pd-extended, is
doable without buffering for partitioned convolution on a modern
computer, but it exacts a pretty high CPU toll, and if I have to
handle random blocksize changes, it gets more expensive.
They cannot vary by themselves, but what is usually done (e.g. with
FFTs), is to place an signal (tilde ~) object in a subpatch and resize
the blocksize for that blocksize using the [switch~] or [block~]
objects. You might consider using this very approach.
Also, since convolution is much more efficient around block sizes of
256 or 512, perhaps I should default to one of these, buffer a little,
and have a runatpdblocksize message or somesuch?
I still have not understood if/how the user can set the duration of the
first partition of you partitioned convolution, and how these partitions
are structured in their (possibly increasing) sizes. Since this first
paramter will define the latency-vs-CPU tradeoff it should not be preset
by the developers.

PS: Pd and Pd-extended use the same core, audio engine. You might want
to consider Pd-extended as vanilla Pd with a folder full of precompiled

The convolution engine has support for doing it either on the calling

The convolution engine can swap-in a pre-loaded ('cached') IR in
realtime without glitching... but it means keeping 2x the Impulse
Response data in RAM. To keep the default API simple but useful, I'm
defaulting to caching only the last 5 impulse responses in RAM.
cachesize N lets you increase that number lets say in a
performance you wanted to use 30 different impulse responses and you
have 2GB of ram... should be nbd.

Yes, disabling this could be a good idea! You could also add a gain 0-1
message for manual control.
Its worth noting that impulse responses are usually whack without gain
normalization like factors of hundreds to millions off a usable
signal.

I'd be interested in what flexibility means in this context, it might
give me some good ideas for features to add. Efficiency-wise, last
time I benchmarked its more efficient than jconv, but the difference
is offset by less graceful degradation under CPU load (I convolve in
background threads to preserve realtime in the main thread while
avoiding an irritating patent that's going to expire soon...).
WRT to Pd's audio scheduling... are Pd signal externals held to
realtime or can my dsp call vary the number of cycles it takes by 100%
from call to call? VST seems to do ok with this, but AudioUnits get
scheduled to run at the very last instant they possibly could. If Pd
can have some variance, I can drop the threads and improve the
external's degradation under high CPU load.

Be advised that there is many ways of mapping faders to mulipliers. Depending on your practice it is common to have the 0dB (unity gain) mark somewhere 4/5 up the fader's range, which is inherited from analogue mixing desks and which I have found useful in the digital domain as well (despite the danger of clipping at the dac). The mapping of a fader's value to the actual multiplicative value is also a matter of feel (tactile). I don't know if there is much research about this topic, I personally prefer the [fadtodb] abstraction by Thomas Musil (iemabs/iemlib) which we use for our productions here at the IEM, and which to my humble opinion comes closest to the analogue desks i love. chease, Peter ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

I want to check its latency and see how efficient it is. Not sure if I get you right here, so let's see: When you use a Wii via Bluetooth into Pd then you don't really need the Arduino (unless there's Arduinos with Bluetooth already). Simply make Pd output Midi controller values which you assign to level, pan, aux etc. in your DAW. Another nice thing could be to make the Arduino output MIDI directly and I think this is not too hard, search the big garbage pile called internet. This would be the equivalent to building a midi fader box essentially. Others might be better at this: If you want to control a DAW's panning with the Wii, be advised that it does not detect rotation. Meaning: If you hold it like a TV remote control and pan it left and right like a compass needle, this does not get detected by the accelerometer. cheez, P ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] logical timing question
Hi all, Frank Barknecht wrote: Hallo, Peter Plessas hat gesagt: // Peter Plessas wrote: i have a question regarding timing in Pd: I understand that messages to tilde objects just get passed to the DSP tree within DSP blocks. How about the reverse? Found out that snapshot~ is returning the last sample of the last block during which it got banged. This is fine, since it is the sample value most closely to the output of the result. Now when i use the following setup: [bang~] | | [t b b] | | | | [timer] i get a minimum logical time of 1.45 msec (aquivalent to 64samples at 44.1 kHz) even when i use a blocksize of [block~ 32]. I think, bang~ should bang after each block, so with [block~ 32] it should bang every 32 samples. But it seems to have a lower limit of 64 samples. Don't know why. thanks for the reply, Frank. That's what made me curious. Since the duration of a DSP-block does not belong to the realm of clock-delayed messages (pd can't know of the exact duration of the DSP block, assume f.e. an external audio clock with jitter) those values may have to be sampled by the messaging system. This sampling would then appear at a minimum rate of 64 samps. So bang~ only makes sense for blocksizes greater than 32 samples, right? Phew, does that make sense? Still trying to completely understand that. In general, Pd has like to times: One is the time realm of clock-delayed messages, i.e. everything that originates in a clock objects like metro, delay, pipe, qlist, etc. Clock delayed messages have sub-sample accuracy. This is achieved by tagging each normal message with a time tag, similar to the old time tagged triggers in t3_lib. The tags for clocks are invisible, though. Timing is a very interesting topic in pd (and with computers in general). When i try to measure the [realtime] of a [metro 4] object, i get: print: 11.351 print: 0.122 print: 0.11 print: 11.402 print: 0.088 print: 0.119 print: 11.374 I think you get the same values. Can it be true that there is a deviation of 7ms now and then? More interesting: Why is it not only now-and-then, but every fourth sample? So there must be some phase shift which accumulates in the operation of [realtime]. On averaging those values, one gets a value close to 4ms though.

Does anyone know about the real-life resolution of [realtime]? those time steps seem to be related to the audio driver. you seem to run pd on jack with a latency of 23ms / 512 frames per buffer @ 44.1kHz. when i use 2048 per buffer at 44.1kHz, i get 92 ms latency and the numbers look like this: I did this test with -audiobuf 50 running OSS. You are right, the values differ greatly on the kind of audio driver i am using, f.e. with alsa and -audiobuf 50 i get: print: 0.1 print: 4.928 print: 4.991 print: 4.951 print: 4.994 print: 0.098 print: 4.931 print: 4.994 print: 4.949 while using alsa and -audiobuf 100 the result is slightly different as well. And all this while DSP processing is even turned off. i guess, if you want really accurate realtime values, you would have to go for the least possible latency, since it seems, that time of execution of pd is completely dependent on the audio driver. and even if this would cause drop-outs, the results of [realtime] wouldn't be affected in a way, that the overall measured time is still valid. if you use [timer], which measures logical time, and you get drop-outs, all dropped out time is not part of the measurement and you will get wrong (too small) values as a result. So realtime is dependent on the audio clock? I always thought that it took the cputime/OS time... I understand that logical time in timer is the internal perfect representation of pd's time. i never understood, why [timer] is giving different values from the ones that you expected, when connected to a [bang~] inside a re-blocked subpatch. would be cool to have that either explained or declared as a bug.

Re: [PD] Seamless recording of 2 consecutive audio files?
Dear Frank, list, probably having found the culprit, it looks like recording two consecutive 24bit .wav files using the [open -bytes 3 foo.wav] message does introduce a small click at the gap. This behavior is independent of weather the bangs are timed to blocksize intervals explicitely. Can anyone else confirm that? I glued the two file together using sox, and audibly and visually find a small click at the boundary. see attached modified version of Frank's original patch. regards, Peter Frank Barknecht wrote: Hallo, Florian Hollerweger hat gesagt: // Florian Hollerweger wrote: Is it possible to record 2 audio files with [writesf~] in a manner that the second starts exactly after the first one stops?

[PD] logical timing question
Dear list, i have a question regarding timing in Pd: I understand that messages to tilde objects just get passed to the DSP tree within DSP blocks. How about the reverse? Found out that snapshot~ is returning the last sample of the last block during which it got banged. This is fine, since it is the sample value most closely to the output of the result. Now when i use the following setup: [bang~] | | [t b b] | | | | [timer] i get a minimum logical time of 1.45 msec (aquivalent to 64samples at 44.1 kHz) even when i use a blocksize of [block~ 32]. That makes me assume that the sampling period for an external process (such as an audio clock, represented by bang~) is limited to 64 samples. What is also interesting, is that i get the double value of 2.9 msec for blocksizes above 64, for example 65 and above. There are no adc~ or dac~ objects or any subpatches in this setup. So, with predefined timing objects (such as [del]), the resolution of the logical time in [timer] can be as low as a fraction of a millisecond, while non-deterministic events get sampled every 64 DSP ticks (or probably integer mutiples). All still confusing somehow, looking forwards to any answers! regards, Peter ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] sound device positions change after reboot Pd uses wrong soundcard

* Andy Farnell [EMAIL PROTECTED] [2008-02-05 23:33]: You're spot on there. I will develop the stereo image as I work on the environment model. But interestingly enough, lightning _is_ an explosion, one hell of a big explosion. The plasma is as hot as the Sun for an instant and that's why the air expands, the energy in a lightning bold makes most bombs seem like little fireworks. The difference is, and this is unusual, it radiates in a cylinder not a sphere, and sound comes from a simultanoeus extent (because the bolt moves at the speed of electricity which is closer to the speed of light than the speed of sound) Isn't the noise happening when the light/plasma channel is collapsing after the lightning happened? regards, Peter ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] live coding, [was: Re: paranoid pd]
Hi Tim, I havent seen many examples yet around here though. Are many people doing this with pd ? The pd-graz group has done a variant of live-coding in its 'blind date' performances. There we take a teamwork approach, letting multiple players edit the same patch at the same time on stage during performance. In the past this was done using multiple mice and keyboards connected to one machine, but we switched to IOhannes' 'multipd' which uses a special proxy written in pd itself which interconnects itself between the gui and dsp part of pd and contributes all events (mouse clicks, object creation) amonst various clients. For the live coding itself, we decide not to use too many abstractions, since we require our patches to be readable by all players, and to make the coding reproduceable to the audience. We definitely start from zero, so the beginning of each concert is, well, silence. The past performances of pd-graz were at Musikprotokoll Graz, Roxy/NoD Praha, PdConvention2 Montreal. See: http://pd-graz.mur.at/concerts/blinddate/praha/praha_pics http://umlaeute.mur.at/Members/zmoelnig/dissertation/papers/pd2007/patchingtogether_slides.pdf glg, PP Is there an audience for it, or is it just pd-geeks who enjoy it? (not that th?t's not an audience ofcourse :) ) Do you start from zero, or do you open an existing patch and start modifying that ? do you restrict yourself to 'basic' objects, or do you use alot of abstractions (so the audience doesn't really see things being built-up from zero)?

Re: [PD] fs1r pd sysex
* Timmy [EMAIL PROTECTED] [2008-01-26 13:05]: random question, just a thought, but do any of you think it would be possible to build a sysex editor for something like a fs1r with pd ? i have some software that i can edit it with, but i cant edit it and play sequences with it at the same time.. its like the editor has complete control over the midi port and wont let it up to any other midi sequencer/program, i've tried using a midi yoke, but that doesn't work either... sorry for the kind of indirect pd question, i just wondered if i went about investing some time into building something with pd i could still use external software to record and playback sequences.. Dear Tim, random answer, it is definitely possible to build a sysex editor in pd. The more tricky part, especially for a newcomer is the handling (storage/retrieval) of the many different data values in pd. Not that it is not possible, but better have your homework made before that :-) If you want to start working with pd, that would make a good project to do so. But if you want to have a quick and working solution, i would try other things, as for example a multiport midi interface, or midi mergers or other software loopback solutions. regards, PP all the best mr tim x -- a man's life goes some ways the way his life will be [EMAIL PROTECTED] wrote: Send PD-list mailing list submissions to pd-list@iem.at To subscribe or unsubscribe via the World Wide Web, visit http://lists.puredata.info/listinfo/pd-list or, via email, send a message with subject or body 'help' to [EMAIL PROTECTED] You can reach the person managing the list at [EMAIL PROTECTED] When replying, please edit your Subject line so it is more specific than Re: Contents of PD-list digest...

Re: [PD] [OT] slightly: building audio computer with PD

I just switched from a normal 2.5 IDE drive in my laptop to a compact flash card using an IDE-CF adaptor.

Re: [PD] [OT] slightly: building audio computer with PD
* Derek Holzer [EMAIL PROTECTED] [2008-01-01 22:18]: Either way could work, the ramdisk is a particularly good idea. Unless the installation is networked, there's not too much need for logfiles in the classic server or multiuser environment sort of sense. You could probably also just disable to logging daemon by removing it from the boot scripts using rc-update (on Gentoo at least, or with another distro-specific equivalent). I imagine that logging would simply just fail quietly if the partition were read-only... I mean, what would log the fact that the logs weren't logging? ;-) Right, that's a nice point in particular!

Re: [PD] Meaning of -noprefs
Hi, I think -noprefs should stop .pdrc as well, since it's in the spirit that is great news! Btw, is there a document on the available options in .pdsettings? For example: Does defeatrt: 0 imply -rt? Otherwise, how does one set -rt? Which Audio-API is which number? Let me take the opportunity to address two other issues, both already discussed a lot on the list but still worthy to address: Hiding hidden folders in Tcl's file dialog. (1) The position of objects being pasted into a patcher. (2) After almost five years of working with pd a lot, these two things are the ones, that bother users (like me) the most. They might be hard to solve, but are still necessary to solve. One can live without much eye-candy and other 'nice-to-have' features very well. But those two things are an obstacle to everyday work in pd, because (1) is slowing the work down, and (2) is causing confusion. thanks regards from Peter * Miller Puckette [EMAIL PROTECTED] [2007-12-05 23:46]: Hi all, I think -noprefs should stop .pdrc as well, since it's in the spirit of being able to find out whether a problem is coming from the configuration or from Pd itself. If it's reasonably easy to do I'll change that. That said, I think .pdrc should be regarded as deprecated, unless there's something you can do with it that can't be done in .pdsettings instead. cheers Miller On Wed, Dec 05, 2007 at 09:31:31AM +0100, Peter Plessas wrote: Dear List, Simon Thanks Simon for your kind reply and explanations So although there might be space for calling that behavior an additional but questionable 'feature', i consider it an inconsistency in user interface design.
