I'm having trouble playing some AIFF files (getting the typical "Unable to open item for playback (Unsupported format or corrupted file)" message from the console). From the little research I did, I think it has to do with the "ANNO" chunk at the very end of these files.


I'm not too familiar with the AIFF specs, but if it changes anything, here's what the header of one of the files looks like:

CODE
FORM   46 4F 52 4D
...   00 0F B7 03
AIFF   41 49 46 46
COMM   43 4F 4D 4D
....   00 00 00 12
....   00 02 00 03
...   EC 1C 00 10
@.D   40 0E AC 44
....   00 00 00 00
..SS   00 00 53 53
ND..   4E 44 00 0F
x..   B0 78 00 00
....   00 00 00 00
..     00 00



The ANNO chunk looks like this:

CODE
ANNO   41 4E 4E 4F
....   00 00 00 17
http   68 74 74 70
://w   3A 2F 2F 77
ww.s   77 77 2E 73
ampl   61 6D 70 6C
es4.   65 73 34 2E
com    63 6F 6D


If I remove the ANNO chunk completely, or just add bytes to it, the file plays. The original files all play in most / all other software (Winamp, Adobe Audition, iZotope RX2..), so I think this has to do with foobar2000.

Anyway I hope I provided as much information as may be needed, and that you can solve this.. eventually!



I am on Windows XP. I've tried opening them in foobar2000 versions v1.1.16, v1.2 and v1.2.2 (v1.1.16 and v1.2 as portable versions, without any added components or anything).
