Hi
I'm trying to get audio files from DVDs that I have authored but not
burnt. I use Demux or Osex or DvdExtractor but it seems that the
extracted audio files can't be re-saved or exported from QTPro as AIFF
or whatever. I get either .m1a or .m2a or AC3 (not recognized by
A-Pack).
How can I transcode these files towards MP3 or AIFF - or a true AC3 ?
You'll need to decode them first... I use a command line tool for my
mpeg audio decoding, if you're comfortable with that I can let you know
how it works.
Cleaner can do it easily.
I don't know of specific freeware/shareware tools, but I'm sure if you
searched Versiontracker.com for "mpeg" you'll find plenty of tools,
some of which at least should have MPEG audio decoding. Or, as I said,
if you're comfortable with command lines then Fink has an excellent
tool available...
Once you've got uncompressed (PCM) audio, you can dump that into your
DVD directly, or compress it to AC3 using A.pack, or to MP3 using
iTunes or lame.
