A. yes you can, follow those steps
- create a separated jar (ssrc.jar) file including ssrc classes. (never include those .class files into your application jar file)
vavi/sound/pcm/resampling/ssrc/SSRC.classvavi/util/SplitRadixFft.classvavi/util/I0Bessel.class
- ⚠ caution:
- your application complies with the LGPL. customers have a right to reverse engineering your application.
- if you include ssrc.jar with a distribution, you must offer a way to get ssrc source code.

- on macos m2 ultra 1st pass is in a blink of an eye
