  • Summary changed from purevoice: too small buffer for bitrate to broken demuxing of qcelp/PureVoice in aiff

What created such files?

QCELP in aiff have hardcoded block align, which is correct only for cbr case when only 35 byte frame is used.
Usually each frame have first byte that maps to frame size, so definitely this is demuxer bug.

Replying to richardpl:

What created such files?

I don't remember correctly, but I probably used some external tool which supported QT components for writing.

(Attached files plays ok with current QT)

Actually QT itself creates such files - there is a possibility to select 7000bps or 13000bps mode for encoding.

  • Analyzed by developer unset

Patch on mailing list.
Do I understand correctly that it is not possible to select a smaller bitrate?

Should be fixed, thank you for the samples!
