This might not be a bug, but might help people who fine-tune decoder. Ergo:

I downloaded (while testing LimeWire Gnutella client) a badly mangled Simon&Garfunkel's tune. It was missing a part near the beginning, CRC was bad, and VBR header missing or bar (all as reported by MP3Trim). Old decoder played it without a hitch (as does, say, WinAmp). Even the timecodes were reasonable.

The new decoder plays it up to the place where the piece is missing normally, then shifts in sixth gear: it plays the tune at approximately double speed (with the corresponding frequency shift). After finishing, it repeats the last part at normal speed.

The version 'repaired' by MP3Trim plays up to the missing piese, and then the player complains about bad format. Forcing it to play advances only a fraction of a second, then it complains again etc.

In the case somebody wishes to inspect the file, the zip with both original and MP3Trim-processed tune and their tag files will for the next few days be here.
