It's just a little app to show the API to programmers, and to test
if a soundcard works with the library. It just loops back the first
two inputs to the first two outputs.

Will do.

The 'quality' parameter has a range of 16 to 96, it sets the length of 
the multiphase filter used for resampling, 48 will be OK in most cases.
CPU load by the resampler is roughly proportional to this value. Full
story in zita-resampler/docs/index.html.
