ec8008b086 Adds many syntactically unnecessary casts to silence MSVC C4244; fix an MDCT encoder reset bug. 
st->tonal_average was being set to 1 instead of 256 on reset in floating point builds, otherwise the object code is unchanged.

75d27803d5 Adds many syntactically unnecessary parentheses to silence MSVC C4554.

de0b977547 In VBR the MDCT modes rate control could dramatically over/undershoot after a frame size change 
because the adaptive rate control offset was not being scaled.

222494f3ea Adds a floating-point API to Opus 
The high-level Opus encoder and decoder can now be compiled as
either fixed or float. Also, we now use the stack_alloc.h macros
in the top-level Opus code.

58ecb1ac15 The encoder would crash in the PVQ search if fed NaNs via the float interface. This patch protects against it in two sufficient ways: Making the PVQ search robust against NaNs and by squashing NaNs to zero on input. 
Thanks to David Richards for reporting this failure mode.

fdd867534a Stop adjusting the VBR drift during silent frames, this prevents overshoot after silent spans. This also results in undershoot on files with lots of silence, but this is desirable in terms of increasing quality consistency. It will be even better if we later include some open-loop correction of the targets. 2011-04-13 17:15:55 -04:00

9dec74d98d Adds support for decoding stereo streams with a mono decoder 
We don't allow *encoding* a stereo stream with a mono encoder
because that's just silly.

ff96b165fe Removes the celt_mode_info() call. 
Adds a CELT_GET_LOOKAHEAD() ctl() call instead. Other uses of
celt_mode_info() should not be needed anymore.
