h1. Summary of results
We compared
* @decimate@: the "Decimator"http://code.soundsoftware.ac.uk/projects/qm-dsp/embedded/classDecimator.html Decimator implementation in the "qm-dsp":/projects/qm-dsp library, which uses an 8-tap IIR lowpass filter;
* @resample_hq@, @resample_mq@, @resample_lq@: the "Resampler":http://code.soundsoftware.ac.uk/projects/qm-dsp/embedded/classResampler.html Resampler implementation in the "qm-dsp":/projects/qm-dsp library, which uses a lengthy Kaiser-windowed sinc filter, at three different quality settings;
* @src@: the sndfile-resample program which uses "libsamplerate":http://mega-nerd.com/SRC/, a well trusted resampler also using a Kaiser-windowed sinc implementation, at its default quality setting;
* @zoh@: the sndfile-resample zero-order hold resampler, which just takes every Nth sample without any filtering, serving as a baseline.
