hey ed,
this is what im using:
http://www.amazon.com/gp/product/B0069L9PZA/ref=oh_details_o05_s01_i01
its small and i got it because the usb plug is attached to a small cord so the in/out can be tucked somewhere (under the board?)
anyway... sound out is decent...
still no usable sound input though. as soon as i dont do -noadc the output gets all crackly. although even though it was crackly i did plug a guitar into the input and it sounded fine... other than it being all crackly that is...
oh and this was just using pd test patch.

Hey Cyrille,
How big is the external USB soundcard? I'm really interested in the Pi as a very small device for running Pd, and my USB soundcard is good but really big compared to the form factor of the Pi. I'd be interested if anyone has found a soundcard that works well and has the same compact style - the cheap ebay dongle-sized ones may not be so good, but they are small. Does anyone have a good experience with one of these on a Pi or a regular PC machine?
I'd like to build installations with many Pi's emitting sound all at once, and so a small soundcard is a good thing :) Ed

using 0.44, we manage to have it running with 25ms audio buffer using an external usb soundcard. 85% cpu about. no clicks.

One slight tweak: if you type "sudo chmod 4755 /usr/bin/pd" you will probably be able to use the mouse clicklessly (at some expense to security!)
This will be unnecessary in release 0.44...

Dear List,
I managed to get the phase vocoder working on my Raspberry Pi, with the standard Raspbian wheezy distro. It works ok under the following conditions :
- no GUI activity (even moving the mouse results in awful scratches)
- the "delay" in Pd is set to at least 50ms
- 224 Mb of RAM is allocated to the CPU.
All this using the internal audio output.
This is quite encouraging...
Cheers,
Pierre.
