[BNM] Sound File Geeks...

[Mike Pelton]

So... thanks for the suggestions guys but the plot thickens. GSpot and VLC
can't read it while Audacity can, but Audacity doesn't offer any codec info
(unless I'm being dumb which would be unprecedented ha ha).

Any other thoughts anyone?

Thanks

Mike

Try also GSpot (Windows only)
http://www.headbands.com/gspot/
which gives you the lowdown on video+audio codecs.  I'm not sure if it
only does audio files (can't see why not though), it pulls out the
codecs for movies just fine and high-lights whatever it thinks is
missing.

QuickTime Pro (paid-for) also has a nice Media tab that explains
what's going on, though that's presumably just the same info that
VLC/mplayer/Audacity will expose.
