Michael Niedermayer	7d636d02b1	swresample/dither_template: Add missing license header Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Michael Niedermayer	223a859853	swresample/dither_template: Do not define macro functions to nothing This avoids potential warnings Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	cc4a41727e	swr: fix "may be used uninitialized in this function" warnings The uninitialized use implicates 0 channels, which is unlikely to reach this function but fixed anyway in this commit. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	c8737d348b	swr: work with 4 noise shaping coeffs at a time 63->38 kcycles Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	ef7fdc8cff	swr: use a local variable for ns_coeffs maybe a very tiny bit faster Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	68ff7d265f	swr: use local variable for ns_errors 71 -> 63 kcycles Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	b5d9e5d06c	swr: minor simplification for the noise shaping pos update Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	2eec98125e	swr: mark noise data for noise shaping as const Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	558aa6cab7	swr: add seperate in/out pointers to the noise shaping code Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	fca51256d4	swr: rename dither_pos to noise_pos THis more closely matches what the field represents Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	0b60fc94aa	swr: reorder the operations in the noise shaping code Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	3ab1970612	swr: move dither related fields to their own context Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	82742294b7	swr: Implement Noise shaping dither The following variants are implemented: lipshitz noise shaping dither shibata noise shaping dither low shibata noise shaping dither high shibata noise shaping dither f-weighted noise shaping dither modified-e-weighted noise shaping dither improved-e-weighted noise shaping dither Data tables taken from SOX Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
