017d4455da pitch gain is now celt_pgain_t 2008-02-26 16:19:03 +11:00

b60340f7e3 fixed-point: band energy now a 32-bit value. It might have (barely) fix into 
16-bit, but at this point, it's not worth the trouble and loss of accuracy.

e901fe35b8 fixed-point: added a celt_ener_t type for band energy. 2008-02-26 14:46:26 +11:00

b4dfce4665 fixed-point: Using a NORM_SCALING of 16384, sig_norm_t is still a float though. 2008-02-25 17:41:30 +11:00

2c1d2f5bcc MDCT now scales down by N/2 instead of N/4. The factor two is moved to the 
overlap-add during synthesis.

c5eba7b3ec Don't flush the last buffered symbol if it is zero. 
When rng starts out 0x80000000, this can cause an extra zero byte to be written
 to the stream.
