Ken Cooke	3555e90cf6	Improved random generator for SIMD dither	2015-10-01 20:32:48 -07:00
Ken Cooke	e1e34b2ce5	Fix to allow arbitrary input/output buffers from caller. SIMD padding is no longer required.	2015-10-01 20:17:04 -07:00
Ken Cooke	4e29d8382d	SSE2 optimization of new resampler. 3.5x faster for all modes. Dither is always enabled.	2015-10-01 03:24:10 -07:00
Ken Cooke	aa01dca0a8	Fix compiler warnings	2015-09-27 19:14:31 -07:00
Ken Cooke	7faada24a8	Moved table to the top, so it can be declared static	2015-09-27 15:45:00 -07:00
Ken Cooke	c000c635b1	CR feedback	2015-09-27 15:31:11 -07:00
Ken Cooke	956d83c872	Size optimization of new resampler. Reduced size of precomputed tables by 8x. Even with 32x oversampling of the prototype filter, aliasing from Lagrange interpolation is (12+24/octave) = -132dB which is fine.	2015-09-25 21:28:48 -07:00
Ken Cooke	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
