66 - Oversampling: Some emulator backends (currently only SIDPlay 2)
67 support technique called "oversampling", which further enhances
68 audio quality. Oversampling is done by computing audio data to
69 higher rate (factor * samplerate) and then downsampling with
70 rate-conversion filter.

72 This results in smoother waveforms, but it consumes very much
