54fb7e5683 Tuning the bias for the L1 tf metric 2010-10-15 11:26:32 -04:00
Jean-Marc Valin
8852563a2e Unb0rked the VBR code: several units issues that made VBR completely useless 2010-10-15 10:24:53 -04:00

8200b2d16c Modifying the L1 metric for tf analysis by merging together all frequencies. 
Still need to make it use the right channel in stereo.

83c26fbd7b Fixes a ibudget bust and a divide-by-zero at very low bit-rate 2010-09-29 20:05:36 -04:00

d74c851feb Adds a simple dynamic allocation scheme 
This should help on highly tonal signals by increasing the rate of
bands with a lot more energy than the neighbouring bands.
