Hi,
@ Miller : I think it's Pd 43 something (I use 42 on my latptop and it look slightly different). Unfortunately the phase vocoder example doesn't work, I do get some sound out of it but only in small distant chunks. Even the pitchshifter example doesn't work. The reverb example does work though. Please note that I tried all of these with the ethernet cable plugged in, I think it was using a substantial share of the CPU.
@ Richie : I haven't tried the GPIO yet. I find it a bit frustrating when they say that audio input can be added easily through the GPIO. I don't think it's true. It would take a lot of hardware around a good ADC, plus I guess a custom driver. There aren't any DIY audio ADCs on the web that I know of, except a project by a German guy who builds ADCs and DACs frm scratch.
One thing I would like to know is how difficult it would be to run Pd on this machine at a very low level, with a very minimal OS (I know nothing about this kind of things). 700MHz is a lot I believe, considering that a lot of digital audio gear was available before this chips were affordable. I'm pretty sure that a standard digital multi-effects for instance doesn't need 700MHz at all. I've been dreaming of building this "Pd box" people have been talking about for many months now, and I can imagine what a revolution it would be if it was open source.
Cheers,
Pierre.
This is really excellent news! I haven't tried Raspbian yet. I will as soon as I have some time. Has anyone tried accessing the GPIO with Pd yet?

Thanks to whoever made this happen -- I think some of the credit goes to
Guenter Geiger who packaged Pd for Debian. I'm curious - what version
of Pd cane up? And can you run the phase vocoder (audio example
(doc/3.audio.examples/I07.phase.vocoder.pd) ? That took $30,000 worth
of hardware when I first got the equivalent patch running around 1994.
cheers
