Comment (by Desperado):

 Replying to [comment:3 pross]:
 > The length (1h08m11s) is an estimate based on the file size. The file
 only contains 3 seconds of standard VOC audio packets. The remaining
 packets are "other" data that ffmpeg skips over during playback:

 Thanks for the answer. Are you sure that the "other data" cannot be
 decoded in the same manner as the first 3 seconds? For example, if you
 restarted the decoding one byte after the end of the 3 second block, would
 it work?

 If not, do you see any other obvious audio data in the "other" data?
