-libmad:
- - more API layers (buffering, PCM samples, dithering, etc.)
- - x86 performance optimization compiler flags
- - function documentation, general docs
- - finish async API
- - parse system streams?
- - MPEG-2 MC, AAC?
- - logarithmic multiplication?
- - multiple frame decoding for better locality of reference?
- - frame serial numbers, Layer III frame continuity checks

-libmad Layer I:
- - check frame length sanity
-
-libmad Layer II:
- - check frame length sanity
-
-libmad Layer III:
- - circular buffer
- - optimize zero_part from Huffman decoding throughout
- - MPEG 2.5 8000 Hz sf bands? mixed blocks?
- - stereo->mono conversion optimization?
- - enable frame-at-a-time decoding
- - improve portability of huffman.c
