Hey guys, hope you can help me out...

Is there a freeware commandline tool for converting an MP2 audio file to WAV
format? I want to use it in a Rexx script for automating the conversion
process.

In addition to posting a response here in the newsgroups for others'
benefit, could you also e-mail me at (e-mail address removed)?

Thanks for any help.

Regards,
Mark

LAME will do that. You need to use the switches --mp2input --decode.
There's a LAME switch reference page at
<http://lame.sourceforge.net/doc/html/switchs.html>. AFAIK, the best
place to get LAME for Windows is said:

I seem to be having some server trouble, and I'm only posting this
here. Maybe someone else will pass it along via e-mail.
 
Ah...I didn't realize there was a lame.exe...I had only seen the lame.dll
file on my system at work. I've installed lame 3.96.1 and now see the
lame.exe. Works like a charm!

I can't believe how much time I've wasted looking for a commandline program
to do this, when it was there all the long in lame.exe.

BTW...has anyone run into any problems converting directly from MP2 to MP3?
All the long I was using dbpowerAMP to convert MP2 to WAV, loading the WAV
into Cool Edit for editing, THEN saving to MP3, and this always worked fine
(tedious, but no file conversion problems). Then I thought I could save a
step by converting directly to MP3, skipping the WAV format. But, whatever
program it was that I used to convert directly to MP3 actually trimmed my
file, with the resulting MP3 file being cut off either at the beginning or
end (can't remember which). Was probably a problem with just the program,
but I was wondering if there might be a common problem with this type of
conversion one has to look out for.

Thanks very much for your help!

Thanks for the suggestion re: Lame...

Now, my problem is figuring out how to get my MP2s to convert to MP3 stereo
files. I tried the "-m s" option, and the "-m force" but these don't seem to
do the trick. Whenever I used dbpowerAMP to convert my MP2s to WAV, the
resulting WAV was in stereo, and I edited it that way in CoolEdit, saving it
as MP3 when complete. I basically want to skip the WAV conversion, and go
directly to MP3.

Any idea what I might be missing?

Thanks again for any help...

AFAIK, with LAME you'd have to convert the MP2s to WAVs then the WAVs
to stereo MP3s. I don't know of any codecs that will convert MP2s
directly to MP3s, but that's not to say there aren't any.
 
Ok, I have MP2s that are in mono, and all the long, while using dbpowerAMP
to convert to WAV so I could edit them in CoolEdit 2000, they became stereo
(or dual channels...whatever). Then I saved them as MP3 once done editing.

I've been trying to get Lame to convert to stereo, but haven't figured out
how; then, when I realized the MP2s were mono, I wonder if there is any
advantage to converting to stereo anyway?

Insights? Any advice would be appreciated.

Thanks,

Reencoding the files to MP3 will degrade the sound quality. If you edit
the files with a MPEG editor like mp3DirectCut (www.mpesch3.de) you don't
have to reencode and keep the sound quality in tact. Of course CoolEdit
can do a whole lot more than mp3DirectCut so if you do complicated things
to the files this is not an option.
