Wicked ? Sounds rather Harry Potterish...

I wrote libzita-resample mainly for high-quiality real-time SRC
of multichannel audio, and it's a compromise between 'numerical'
quality and CPU load. But so far nobody has been able to hear the
difference with a no-compromise algorithm in a series of listening
tests (all audio experts and musicians).

The current API implements the trade-off, but internally there are
more free parameters, and it can be extended easily if necessary.
There's some discussion about this in the docs that come with the


Laboratorio di Acustica ed Elettroacustica

Lascia la spina, cogli la rosa.
