The sound sample above is from here.

I've uploaded 2 problematic samples for the v6 aac, but they are extreme
exceptions, rarely happens in the real encoding situations. Generally, the
v6 patch is a very good patch, the quality is satisfactory. If you upload
the patch that prevents the speech bitrate bloat, I'll start testing. The
opponents are here.
- v4 abr
- v7 abr
- v7 vbr
- fdk-aac cbr
- libfaac vbr
- ac3 cbr
- libmp3lame vbr
BTW, I prefer the name v7 rather than the v6b, even if the revision is
minor. It's easier to explain.
