FFT Resampler
...ler. At the moment it works in floating point only, and only basic quality inspection has been done. Some benchmarks comparing the filter-based resampler at Q3 with the FFT resampler with overlap = in_len / 2, using 20ms chunks of data. (-O3 -ffast-math, FFTW3, gcc 4.3.0 on x86_64) 16=>48: 59us vs 19us 16=>44.1: 204us vs 34us 16=>8: 13us vs 7us 48=>8: 32us vs 16us This is actually much faster than I expected. With -O3, the overhead of copying, applying window etc is 20%. With all options, the overhead sinks to 10%. I've done listening tests when converting wb_male.wav to...
