some tuning to fine energy allocation and prevent it from going above 7 bits

(at which point, it causes problems)

Turns out that the worse case of the vector split is the same as that of the
...
pulse split. Also, added an allocation line for even higher bit-rates

Adjusted stereo bit allocation to be higher than mono for the same alloc line
2008-05-30 16:07:06 +10:00

bf2d648bbd
Implemented intensity stereo, which required changes all over the place
...
to make sure that stereo coupling is done at the band level. Previously
the stereo coupling was done all at once, but there were all kinds of
interactions with the prediction and folding.

Fixed a bug in the PLC and added code to estimate the pitch from the synthesis

instead of relying on the one previously transmitted by the encoder.

Reworked the static modes. Now, if all static modes have the same frame size,

overlap or number of channels, we can pass the hint to the compiler.

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.
2008-03-11 10:43:06 +11:00
