[linux-audio-dev] jack_process and pitch-shifting

[Olivier Guilyardi]

Hi,

In Jackbeat, I want to include support for realtime pitch shifting. One 
of the option is to use a quality resampler as libsamplerate's 
SRC_SINC_BEST_QUALITY converter.  In the future, I may add support for 
libsoundtouch1 (http://sky.prohosting.com/oparviai/soundtouch/index.html).

Can I do that in the jack process callback ? Or should I span a new 
thread and do the heavy job in there, ringbuffer'ing the result to the 
RT thread ?
