Somebody scribbled about [expert] Alternatives to editing mp3/ogg files in 
Audacity?

70+ meg mp3 files? I might have some that big.

Much of my hour-length stuff are OTR mp3 which don't require a whole lot 
of extra space - perhaps 10-15 megs vbr for much of them. It would seem 
that the trick is to be sure that the whole uncompresssed file (plus 
edits) is going to fit in memory.

Depends on what you want to do. If you can export them first as wav, you 
can do some editing with sox. If you know (roughly) the start and end 
points, factor in the # of samples and size you can try to do some low 
level splicing with 'dd'. But that works best with headerless sound 
files.

It's much easier of course to have a visual guide though. Audacity does do 
a good job overall - except that it crashes here too. I tried noise 
removal on a part of a sample mp3 and managed to crash it, but I don't 
think memory was an issue. Also the version I have here (1.1.3 from 
textar) seems a lot more buggy than the older version I had before I had 
my wierd system crash a few weeks ago. I'm getting a lot of assert 
messages on the starting console, for instance, and much is missing, like 
time marks and such.

Audacity also needs *LOTS* of disk space if you save something as a 
Project rather than exporting to  WAV or MP3 formats. And I still notice 
that exporting to MP3 makes the resulting MP3 double-speed.
