Difference: WavpackHybridSupport (r5 vs. r4)
The Wavpack audio codec supports an unusual "hybrid" compression mode. In this mode, a traditional lossy file is complemented by a "correction" file. When the two are decoded together, the original input bitstream can be recreated exactly. The lossy file may also be decoded on its own.
Rockbox currently handles lossy files but ignores the correction files.
Decoding of stereo hybrid lossless files functions off-target. The off-target with a patch is at http://q3q.us/hybrid2.patch . This does NOT run on a device; use http://q3q.us/codec-executor.tar.bz2 to run the codec!
Decoding on-target works via a modification to A patch enabling playback on iPod targets and in the buffering system sim is at http://q3q.us/buffer.patch http://www.rockbox.org/tracker/task/10537 . This but does will NOT play nice with other files and is not ready for general consumption. yet run in real time.
Currently fixing buffering code interactions to avoid data corruption
