Wim Taymans	a84bf672e8	audioconvert: add dither passthrough flag	2022-06-28 11:31:40 +02:00
Wim Taymans	b5e0151cc0	audioconvert: add dither noise setting in dither struct ... Move the noise setting in the dither struct so that it can be handled separately. Setup dither separately. Set used cpu_flags in structures after setup.	2022-06-28 10:52:31 +02:00
Wim Taymans	b7e26002be	audiocovert: improve dither setup ... The quantize is the amount of bits we want to keep from the original signal, subtract the amount of bits for noise. Clamp this to 0 (all noise). Calculate the scale factor better with powf() and avoid overflows. Fixes #2479	2022-06-28 10:11:46 +02:00
Wim Taymans	67c2202044	audioconvert: improve setup of quantization ... Use the quantize value to specify how many bits to quantize to.	2022-06-27 20:03:30 +02:00
Wim Taymans	00998ffd7e	audioconvert: ensure alignment ... Allocate a little bit more data to ensure alignment and overread of the dither data. Ensure sse2 can load aligned data in all cases.	2022-06-27 17:18:23 +02:00
Wim Taymans	b41d52cfd1	audioconvert: optimize dither ... Add sse2 dither optimization	2022-06-27 14:15:01 +02:00
Wim Taymans	9f55708e9d	audioconvert: Always apply noise when asked ... Rename empty.noise -> dither.noise and always add this amount of noise when > 0. This also adds the noise to silent sounds, not only when nothing is connected because that would also be a problem when an amp needs to be kept alive with an non-0 signal. Rename noise -> dither because we can use this also for dithering later. See #705	2022-06-27 11:19:01 +02:00
