926131291f Add support for a complexity argument to both testcelt and celtenc. 2008-10-08 19:45:55 -04:00

8259531160 API: Change celt_encode and celt_encode_float so that they take an optional synthesis parameter after the PCM input. If optional_synthesis is null the encoder will be able to save some computation. If optional_synthesis is non-null if will be used to write the encoder's expectation of the decoder's output. Synthesis may alias the input pcm, so calling the encoder with the same buffer twice will achieve the old behavior. Remove 'restrict' from the CTL prototype. 2008-09-30 23:32:35 -04:00

9375aa4faa Cleaned up the pre-echo avoidance code so it works when compiled as fixed-point 
(still requires float ops though). Also, removed the per-band IDCT.

949902fd1b const correctness. celt_mode_create() now makes a copy of the static mode 
(if STATIC_MODES is defined) instead of attempting to modify read-only
storage.

8c19b030df Changed _new() to _create() in the API. Added some documentation 
on how to use the API.

a85657bd29 removed // comments and added stack_alloc.h (not used everywhere yet) 
to make the code more C89-friendly.

cb7a2a3d52 Re-ordered the parameters in the stream: [energy, pitch index, pitch gains] 
Also fixed a bug that was exposed by the change (and removed some warnings)

7351e286c8 Everything converted to use kiss-fft. Got rid of smallft and fftwrap. 
Code much leaner now.

012407760c Re-enabled intra-frame prediction, which seems to have exposed a few issues 
with the entropy coder.

4c6bc884c8 "make check" now actually tried to encode and decode to see if things work 
(need to have test files installed otherwise it'll just pass by default)

a76a0b23eb Further simplified the API by passing the rate directly to the 
encode function. Also, trying to properly flush the bit packer
(still some problems left).

11f01729e6 Some cleaning up, a few less warnings and the decoder no longer does an 
infinitete loop in Laplace decoding when the data is corrupted.
