| | | | | | | | | Move ROUND_MUL* macros to their only users and the Celt macros to opus_celt.h. Also improve the other headers a bit while at it. Reviewed-by: Lynne <dev@lynne.ee> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* opus: convert encoder and decoder to lavu/txLynne2022-09-261-5/+8
| | | | | This commit changes both the encoder and decoder to use the new lavu/tx code, which has faster C transforms and more assembly optimizations.

* opus_pvq: do not compile encoding/decoding code if the encoder/decoder is ↵Rostislav Pehlivanov2017-12-041-1/+51
| | | | | | | | | | disabled This should save quite a bit of space if either has been disabled for size reasons. Could just check if the encoding flag is set during runtime on every single location, however the overhead of branch misses would somewhat decrease performance.

* opusenc: implement a psychoacoustic systemRostislav Pehlivanov2017-09-231-0/+556
This commit implements a psychoacoustic system for the native Opus encoder. Its unlike any other psychoacoustic system known since its capable of using a lookahead to make better choices on how to treat the current frame and how many bits to allocate for it (and future frames). Also, whilst the main bulk of the analysis function has to run in a single thread, the per-frame anaylsis functions does not modify the main psychoacoustic context, so in the future it will be fairly trivial to run those as slice threads.
