Hi Romain, 
I have an issue with input.udp that only takes 'string' as input format and
not 'format'.
And also I tried input.external and it seems to not support the
'channels=1'??


regards

Ok, cool! You must know that this format may loose data, thus introducing
glitches in the received stream. (it was actually intentionally coded like
this for artistic purposes!).

You need two things:
  - Convert the source to mono
  - Pass samplerate=32000 to %wav

Thus this should work:
  output.udp(%wav(samplerate=32000, mono), mean(source), ...)

For the input, you may have to convert from mono to stereo with two equal
channels:
  audio_to_stereo(input.udp(...))

I am not so sure about the input part though so let us know if you have some
trouble with it.

By the way, you can also use "samplesize" with the way encoder.
