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 ?
Doing heavy jobs in the process() callback is fine, as long as the CPU
load is deterministic. I this case I think it should be.
