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. > The ajbridge has the same problem. There's the quality-parameter that > defaults to "48" but that's all I get to know about it.

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. Ciao -- FA A world of exhaustive, reliable metadata would be an utopia.
