Converts PCM samples to 16 bit.
If the source format is 24 bit, then dithering is applied.
- Parameters:
-
buffer | a pcm_buffer object |
dither | a pcm_dither object for 24-to-16 conversion |
bits | the number of in the source buffer |
src | the source PCM buffer |
src_size | the size of #src in bytes |
dest_size_r | returns the number of bytes of the destination buffer |
- Returns:
- the destination buffer

Converts PCM samples to 24 bit (32 bit alignment).
- Parameters:

bits | the number of in the source buffer |
src | the source PCM buffer |
src_size | the size of #src in bytes |
dest_size_r | returns the number of bytes of the destination buffer |
- Returns:
