[LUG] Converting iTunes files...

 


I've been given a few file of what looks like apple iTunes format to convert for a customers music on hold - however I can't make any sense of them... file identifies them as:

moh1.m4a: ISO Media, MPEG v4 system, iTunes AAC-LC
moh2.m4a: ISO Media, MPEG v4 system, iTunes AAC-LC
moh3.m4a: ISO Media, MPEG v4 system, iTunes AAC-LC
moh4.m4a: ISO Media, MPEG v4 system, iTunes AAC-LC
moh5.m4a: ISO Media, MPEG v4 system, iTunes AAC-LC
moh6.m4a: ISO Media, MPEG v4 system, iTunes AAC-LC

When I try to play them (with the play command) all I get is garbage - it does vaguely sound like something, but it's running 10x too fast

I've tried mplayer and faad and some Python script to try to convert them to bog-standard pcm files.

mplayer gives this message:

  FAAD: compressed input bitrate missing, assuming 128kbit/s!

so I'm guessing that somehow the bit-rate is missing from the input files - anyone have any clues about what to use, or how to use it?

I don't use Apples iPlayer, nor have I any apple hardware to use either, so I can't actually check them, but the person who I got them from probably knows what he's doing, so I'm assuming the files are actually OK.

Any help appreciated...

Thanks,

Gordon
