Yes, it is a copy of Secret Rabbit Code. We do not use the samplerate library externally, because Jean-Baptiste Kempf advised us to „reimplement“ the resampling and FFT functionality that we need („less dependencies are good“), https://forum.videolan.org/viewtopic.php?f=32&t=124247&p=417507#p417507.
If we should use the existing library in VLC, please advise us how to call their functions (debug messages say they are „undefined symbols“ when being called during runtime, as described in the forum thread).
