If you're doing a lot of mono mp3 -> cdrom stuff, then you might be interested
in this command I found somewhere amongst the ecasound stuff (maillist or
examples):
ecasound -a:1 -f:16,1,44100 -i mono-1.wav
-a:2 -f:16,1,44100 -i mono-2.wav -erc:1,2 -eac:0,1
-a:1,2 -f:16,2,44100 -o stereo.wav
If you replace both mono-1.wav and mono-2.wav with mono.wav, then it makes
the mono wav into a stero wav with the same thing on each channel. It's
simple to stick that into a script and insert that into the conversion
process:
# mpg123 -$OPTIONSfoo.mp3 foo-mono.wav
# dostero foo-mono.wav foo.wav
# cp foo.wav ~/to-burn/foo.wav
HTH,
