Michael Giacomelli dd61978070 Expand the range of the inverse quant table in WMA Pro. Several of the problem samples on the tracker use values outside this range. Trying the larger table doesn't quite seem to fix things, but its only a small amount of additional memory and looking at ffmpeg, I think the larger table is correct.

to build a standalone wma professional decoder.

IMPORT DETAILS

Based on ffmpeg svn r22886 dated 15 April 2010.

The decoder is a heavily modified version of the original ffmpeg floating point
implementation. It's been modified to use fixed point arithmetic and now plays
and seeks on all the targets that Rockbox supports. Currently only supports mono
and stereo streams, streams with more than 2 channels are not yet supported.
