yes, so we use PD dsp-objects to process the data. but samplerate can be 
different.

Yes.

Since autumn, i am trying to set up an kit hardware+software with BBB for
computer-musicians as stomp box, works quite well, after successfully
installed it in a long term sound installation (headless):

some points short:

system:
   + BBB moved to Debian since this year (good)


that is very good to hear!

and the rest means they seem a good choice for embedded, the USB
implementation on the Pis really is a pain,and means you need to be
very selective about what you try to do.


it is also not very clean on others, but improved.

I have never tested a Pi, which kernel version does you use, since there have
been updates on USB since 3.12


a couple of projects last year used usb, but trying several different dongles 
found ones that worked well enough, so we left it at that. My current project is 
HDMI only (plus ethernet for setting up only), so I'm not so worried ... they 
are not here at the moment so can't check, but notes suggest 3.13 probably, I've 
not updated since last year. I'll upgrade tolatest raspbian when they are back.

You mean hooking up the sound card to a different powers supply? I guess
the ones you are using are not USB powered?

Yes.

Since autumn, i am trying to set up an kit hardware+software with BBB for 
computer-musicians as stomp box, works quite well, after successfully 
installed it in a long term sound installation (headless):

some points short:

system:
 + BBB moved to Debian since this year (good)
 + USB Audio works fine und better now with kernel >= 3.12
 + Network performance works better with kernel >= 3.12
 - IO support doenst use device-tree overlays anymore on kernel > 3.8
 + an iio-backend for Jack2 to use the internal AD's 
   in jack for processing sensor data in PD ;-)))  but tricky

sound:

 + down to 10ms with PD and cheap 8 channel out, 2 in 
   USB soundcard Logilink 7.1(EUR 19.90) 
 +  5ms with Logilink stereo USB (EUR 3,90) 
 + success with audio-cape (stereo, but too expensive for the quality)
 - sound quality is normally as bad as on most notebooks, tablets and so on 
 + but with a trick: filtered 5V supply for the USB-card not the USB power
   it seems to get reasonable quality 
   (They have all the same chips like expensive USB cards: C-Media)

I just made a blog on this, but it is not public only for intern usage, if 
anyone is interested in the IEM-embedded-Sound-Kit (doing some audio over 
ethernet stuff) i can make it open (after some polishing, especially the 
english) and release the PD-lib (GPIO,AD,I2C,... interfacing) for these 
devices.

This dev's should also work for Cubie-boards, Wand-boards, UDOO and other arm 
based boards.

Mm well the kernel does it as far as I could tell by watching htop. I think the 
latently is mainly due to the Linaro image not being hard float ...

Re: [PD] [OT] Raspberry Pi Wolfson Audio Card

hey dan, do you have to tell pd to use it’s own core on udoo, or does it so 
automagically? has this something to do with the cpu group from your script (it 
did not exist on my system)

cheers

Re: [PD] [OT] Raspberry Pi Wolfson Audio Card

[Brian Fay]

While I'm sure that Dan is right that the UDOO is the better choice for USB
audio, I do have to say that I've had decent success using my Raspberry Pi
as a guitar effects processor, with the Behringer UCG102 interface.

There's definitely a lot of quirkiness to getting it running... for example
ALSA gets in an infinite restart loop when attempting low latency on
pd-extended, but vanilla starts up fine under the same settings. And then
there's the fact that an issue in the kernel screws up USB audio on major
distros like Raspbian.

I'm using the Satellite CCRMA distro right now with much better success. So
far I've got various delays, a looper, and a waveshaper distortion running
within the same patch, at <20ms latency with very few noticeable dropouts.
Parameters are adjustable with a QuNeo MIDI controller and with a button
attached to the GPIO pins.

The Pi is a bit more affordable than the UDOO boards, but then again I had
to buy a powered USB hub. Ultimately for one audio input the Raspberry Pi
could probably serve most purposes, while the UDOO is more likely to scale
to bigger installations.

Re: [PD] [OT] Raspberry Pi Wolfson Audio Card

[Dan Wilcox]

I don't know the latency. I can try testing that at let you know, but it's
definitely good enough for what I need. It is at least lower than 20ms.
Acceptable latency for guitar is 12ms, and I think I got around 16ms out of
my old setup running on the Pentium III 500Mhz wearable.

The main deal with the UDOO, is that it's multiple cores (2 or 4 depending
on the board you buy). This way, the kernel has a core, pd has a core, and
there are 2 cores left over for other things (my HID-OSC device daemon,
etc).

Hey Dan,

Looks like the UDOO is much better indeed from what you recently posted
here. Could you tell us what latency you're achieving ? And which version
you're using (with or w/o wifi) ?

Pierre.

Ok for small projects, but you're not going to interface a real stage mic or 
guitar easily. Would be much better if the next pi version comes with an 
onboard usb controller, which is the main problem for usb audio on the current 
pi. For now, the UDOO is where it's at for that.

Re: [PD] OT: raspberry pi

[Antoine Villeret]

Hi Patrick,

If you want to play video file with hardware decoding, speed control and
perspective correction (useful with video projector) you should have a look
at my rpi_osc_video_player :
https://github.com/avilleret/rpi_osc_video_player

There is an example pd patch to control it

This is a work in progress, mostly a proof of concept, there is no support
for sound playback for now, but it could be added when I have
time/opportunity

Feel free to try it

Cheers

Antoine

In raspian there's some way to select whether audio goes out the line out
jack or the HDMI port - I can't remember but that should be findable.

Re: [PD] OT: raspberry pi

[Pagano, Patrick]

Hi everyone and thank you for the help and links. I got wheezy up and running 
and installed pd-extended. I could not get audio out of the headphone jack on 
the Pi, but it comes out of the monitor that has HDMI on it. I then of course 
got greedy and over-clocked it and corrupted the file system. grrr. I picked up 
a mini usb audio card a Soundblaster X-fi GO! Pro and in the boot screen it 
sees it and it's in the drop down menu for AUDIO SETTINGS but i cannot do 
anything after i select it and the whole system freezes. I am wondering if jack 
may help with it.
I got pdp working with pdp_sdl as the window outputs, pdp_glx and pdp_xv do not 
work.
I am going to try to get Gedit and Supercollider working before i punt it into 
the Rubbish Bin. I may just use it to control DMX lighting with a USBDMXPro but 
as of now I am need some inspiration for it's use. :-)

cheers~ and thanks

Hey Patrick,

I guess the standard most up to date raspbian wheezy is the best place to start.

For me what's worked best is to find a super-minimal install and then build 
requirements on top of that.

With the project I'm working on atm I couldn't get my pmpd patch to even run 
with the standard install (there is quite a lot going on though).  Now the 
patch runs fine with a whole heap of other stuff on top of that (2 sensors, 6 
channel soundcard etc).  My htop reading fills me with joy-I think there's 
about a dozen processes including 3 shells.

As it's a rev1 board I built a system on top of the hexxeh image (same guy 
who's done the 'rpi-update' program for updating the firmware.  My 
understanding though is that with rev2 boards don't do it.

The one that I've been keeping my eye on, and they've just released a brand new 
version is Mobius
http://moebiuslinux.sourceforge.net/
This is what I'll be testing out for my rev2 boards.

There's a whole host of conflicting info re RPi's out there, particularly 
overclocking to squeeze every last morsel of goodness out of them.  Us audio 
bods have specific needs -  like I want mine running flat out all the time 
without blowing up and there's a big difference with that to someone who very 
occasionally pushes their RPi and wants to tell everyone that there way is the 
best.

My own take has been to only use smaller cards (4gb) from reputable sources - 
very hit and miss though, very definitely YMMV

The raspbian wheezy image will fit on a much smaller card, and will expand its 
partition to fill what you have, and is working nicely here. Clearly not all 
8GB cards are quite the full 8GB.

If you try the standard debian armel it will probably work, but is compiled for

Re: [PD] OT: raspberry pi

[Julian Brooks]

Hey Patrick,

I guess the standard most up to date raspbian wheezy is the best place to
start.

For me what's worked best is to find a super-minimal install and then build
requirements on top of that.

With the project I'm working on atm I couldn't get my pmpd patch to even
run with the standard install (there is quite a lot going on though).  Now
the patch runs fine with a whole heap of other stuff on top of that (2
sensors, 6 channel soundcard etc).  My htop reading fills me with joy-I
think there's about a dozen processes including 3 shells.

As it's a rev1 board I built a system on top of the hexxeh image (same guy
who's done the 'rpi-update' program for updating the firmware.  My
understanding though is that with rev2 boards don't do it.

The one that I've been keeping my eye on, and they've just released a brand
new version is Mobius
http://moebiuslinux.sourceforge.net/
This is what I'll be testing out for my rev2 boards.

There's a whole host of conflicting info re RPi's out there, particularly
overclocking to squeeze every last morsel of goodness out of them.  Us
audio bods have specific needs -  like I want mine running flat out all the
time without blowing up and there's a big difference with that to someone
who very occasionally pushes their RPi and wants to tell everyone that
there way is the best.

My own take has been to only use smaller cards (4gb) from reputable sources
- very hit and miss though, very definitely YMMV

me his rpi xbmc setup which was really good so must be well-doable.

And of course there's a ton of stuff on our lovely list.

Best of luck,

Julian

[Patrick Pagano]

Hello

i just received my first raspberry doo-hickey and i am wondering what 
distro people are using.
I tried the wheezy last night and it seems okay, i installed pd-extended 
after a few tries

I was unsuccessful with getting the CCRMA distro to load onto an 8GB chip

i basically would like to have pd with pdp working, supercollider and i 
assume omxplayer


are there any other essentials i should try?

i would like to use the pi for receiving network GOs for small video 
projections on stage or to fire off small videos from other sources 
[arduino, kinect, wii etc..]



thanks in advance for any comments or help
