 Yesterday paulstretch 2.1 came out: 
 http://hypermammut.sourceforge.net/paulstretch/ 
 Can you tell me how to get sound out of it? Version 2.1 (the 'about'
 says 2.2). I tried with and without jack, mp3, ogg and wav files,
 without any success. I never see jack ports appear. With wav files I
 get the output: AInputS::seek 0 0 54110260 - possible audiofile bug
 (it always seeks to the end of the file)

 Portaudio seems to work, tested with audacity. Any ideas? 
 Did you compile it with './compile_linux_fftw_jack.sh' ?

 I start JACK, start paulstretch, load some mp3 and just press play.
 works just fine with .wav files too and the samplerate does not need to
 match JACK's samplerate..

 FWIW: you can set the environment variable JACK_AUTOCONNECT
 to decide the port-connection behaviour. The default is
 'system:playback_' - setting it to "DISABLE" will leave the output
ports
 unconnected.

 Thanks Robin, it was compiled with './compile_linux_fftw.sh'. I don't
 know why I didn't get audio with alsa either 
because paulstretch does not have an ALSA output.

portaudio to ALSA (or pulseaudio or JACK) should work though, but may
require additional setup. Here (debian/squeeze) it (kind of [1]) works
with alsa-plug, but I prefer the native JACK port of course..

...
  , but it works fine now with
 jack, thanks.
 Paulstretch is quite crazy, I like it :) 
yeah, it's amazing.

[1] there's no resampling and sometimes choppy playback with portaudio.
