a2ea6bf36e Improved audio resampler 
Added LQ mode (2x faster).
Added HQ mode (2x slower), intended for offline resampling.
Default (MQ) quality is slightly improved (512 filter phases in irrational mode).

b4994a3d89 Ambisonic resampler, optimized using AVX2. 
int16_t and float versions.
Removed unused SSE2 version.
Removed unused getExactInput().
Refactored to remove nested #ifdefs.

4a1458e152 Algorithmic optimization of new resampler. All common sample rates now use a rational mode that does direct FIR filtering instead of coefficient interpolation. Complexity reduced by 2x for mono, 1.5x for stereo. 2015-09-25 19:05:55 -07:00
