There's also the Bela platform which mounts on top of a BeagleBone Black. This provides 16-bit audio at 48kHz sampling rate iirc. It also provides inputs for sensors which can be received with [adc~] in Pd. Haven't tried it but looks promising.
Alexandre, in order to get proper audio with C.H.I.P. you need to use the -noadc flag, otherwise the audio is messed up. But its on-board audio is the best I heard so far, compared to the Udoo, the Pi, the Odroid and the BeagleBoard.

can you tell us more about this? this means you cant record and play at the same time, huh?
cheers

Hi, thanks for your answer! I'll definitely have a look at heavy and compare the results with some bits of my own DSP code.
How do you plan to output audio from it? It has SPI that could get you to connect to some DACs but nothing of top quality audio. One can also use PWM to simulate analog out.
I actually thought of connecting ADCs and DACs via SPI, I don't need top audio quality, I'm rather looking for cheap effect/sound boxes :-). On the other hand, the ESP8266 also an I2S interface (dedicated to audio). I've seen videos of people streaming and playing mp3 files with it!
Once I've done my tests (probably not before July), I'll tell my results.
Not sure how cheap is cheap, but the CHIP from Next Thing Co is $9 + shipping http://getchip.com and has audio, wifi, and bt built-in. I’ve been running PD on it. There’s still some issues with duplex audio in PD, but there is vast potential for audio fun on this thing. disclosure: I work for NTC P
