PandaResampler 0.2.0 has been released.
This is a header only library for C++ which implements fast factor 2, 4
or 8 upsampling and downsampling based on SSE instructions. I've
developed the code for my DSP code in Anklang and SpectMorph.
It might be useful for you if you have some DSP loop which needs to be
oversampled to avoid aliasing.
