b35536a3b0 Enabled pure CBR, though there's still some decoder issues. 2008-01-17 16:57:18 +11:00

4fbd18d1f4 Close to getting CBR working 2008-01-17 14:07:55 +11:00

f51ca493fb Looks like the bit allocation code is mostly working. Just need to actually 
use it now.

ec71aee772 A bit of tuning and early work on bit allocation 2008-01-12 23:38:01 +11:00

a2482aceb4 Conversion to 18-band split and fixed a few related bugs. 2008-01-11 11:24:22 +11:00

43e224817c oops, trying not to overflow the 64-bit max allocation. 2008-01-10 17:26:30 +11:00

f8dda66a8e Tuning of the stereo mode, including conversion to the 18-band split. 2008-01-10 17:02:36 +11:00

a4833ffada Stereo decoding working again (fixed a few issues in the encoder at the same 
time)

fdca84b42f Some stereo work (breaks the decoder for now) 2008-01-09 10:44:18 +11:00

95c59ea647 Updated the 18-band mode (mode0) to use the low-overlap MDCT 2008-01-08 16:22:37 +11:00

2875f6bf8d Now using 8 bands for the pitch gain, with a 128-entry codebook. 2008-01-05 13:32:32 +11:00

a5431bfb09 Allowing reduced overlap MDCTs as an alternative 
to multiple MDCTs per frame. Not complete yet.

36d78e6f74 Band energy quantisation info now in the mode directly 2007-12-13 14:59:30 +11:00

4a897680e3 Working on some stability issues (appears to be solved by making the pitch 
projection less aggressive). Also, fixed a 64-bit overflow in the stereo mode
and added a "band rotation" function.

bf94045f41 Stereo almost works now (still need to fix the pitch estimate and add more 
pulses)
 2007-12-10 17:10:29 +11:00

ffa13474ef Adding stereo support. Doesn't work yet, but at least it doesn't break 
mono

aa5bd61cb7 Another experimental mode with longer frames. 2007-12-08 00:27:10 +11:00
