137f3366bc Changed compute_allocation_table() so it handles ebands that start and end in the same allocation band. Also fixed a minor C89 issue. 2010-04-14 17:42:22 -04:00

328b8bd7fc fixed a few trivial bugs: exporting celt_strerror(), changed DB_SCALING to a 
shift and removed the chec for DISABLE_STEREO in the mode creation.

30f7f813ea Changed all the celt*int*_t types to remove the _t suffix, which is reserved 
by POSIX. The other _t types that are not part of the API are still there
for now. Also, got rid of all that was left of the 64-bit types.

80ed147663 The number of channels is now set when creating the states rather than when 
creating the mode. This means that the same mode can be shared for mono and
stereo.

9dff02188c Minor stuff: preventing float underflow in celt_exp2(), preventing the use of 
intra energy for low bitrates, and a bit of very high bitrate tuning

18c1c22e16 Fix for a mode memory leak -- was still allocating memory for the energy 
allocator which was removed a while ago.

ec836da27c Reduce rounding in the mode allocator and remove a scaling loop. 
This breaks the bitstream.
