Hey y'all,
I have a script that I run when I close down my studio
that copies all of my random recordings over to the
'Dailies' area on my web site. But all of these snippets
are .wav files (mostly from Timemachine & Audacity).
I'd like to have the script batch convert all the .wav's
to .mp3's before the copy. That way, my musical partners
don't have to download a 40MB .wav file to see if they
want to work with a snippet. So what I really need is
a high quality command line driven wav->mp3 converter
that I can set up something like:
convertorthang -o=mp3 *.wav
and have it just do it... Oh, and not try to do it
again if the file already exists.
Okay, I'll go Google around, but if anybody's got a good
pointer for me, lemme know, eh? ;-)
toodles!

Hi Jos,
I use lame. From my script:
elif [ "$extension" = wav ]; then
echo "Converting $i to ${i%.*}.mp3 be
patient!"
lame -h $i ${i%.*}.mp3
else
If you want the script, I'll send it to you. It's not
that great because it's partially a learning
experiment and builds an array from the contents of a
directory--not necesarry but you can strip the array
code out. It also assumes the directory structure
~/clients/clientname/wav, ~/clients/clientname/mp3,
etc.
At any rate, Lame produces mp3 files. I use it for
that although I've never listened to one. :)

Okay, cool! Lame is gonna do the trick. I did a few
trial conversions using a command line similar to what
you used and I'm getting a really good compression rate
and totally acceptable quality. Bravo!

Keep in mind you can define id3 tags, and all sorts of things.
LAME works very well.
I use FLAC to archive losslessly compressed audio, and VBR LAME-encoded
stuff for rapid retrieval.
BTW, you can pass a scaling factor to LAME to normalise your samples.
If you have sox installed, you can run a prepass with sox to even tell you
what the scaling value should be! :)
I use a script like the following for batch encoding:
#!/bin/bash
# define min/max VBR bitrates for the stream
MAXRATE=256
MINRATE=64
ARTIST="Megarock Gigadeth"
declare -i newscaleint
newscale=`sox "$1" -e stat -v 2>&1 | cut -b1-4`
newscaleint=`echo ${newscale} | cut -f1 -d\.`
if [ ${newscaleint} -gt 20 ] ; then newscale="20.0"; else
if [ ${newscaleint} -lt 1 ] ; then newscale="1.00"; fi ; fi
if [ "${newscale}" == "1.00" ] ; then
{
lame -S --silent --nohist -q 2 -h --vbr-new -b ${MINRATE} -B ${MAXRATE} \
--tt "Music Track" --ta "${ARTIST}" --ty `date +%Y` --add-id3v2 \
--pad-id3v2 "$1" "$2"
}
else
{
lame -S --silent --nohist -q 2 -h --vbr-new -b ${MINRATE} -B ${MAXRATE} \
--tt "Music Track" --ta "${ARTIST}" --ty `date +%Y` --add-id3v2 \
--pad-id3v2 --scale ${newscale} "$1" "$2"
}

Ok, standard disclaimer.
mp3 is bad, ogg vorbis good! ;-)
I guess there are real world reasons to use mp3 (mainly availability) but they
are quickly going away.
If possible I think one should opt for vorbis.
The latest round of tests:
http://www.rjamorim.com/test/multiformat128/results.html
suggest vorbis is also superior to mp3 when the best encoders are used.
Ogg ogg ogg.

Bladeenc is much easier but, more importantly, why use an inferior
format. Ogg Vorbis is much better. Use oggenc. If your friends are
running Windoze they can use the latest version of Winamp to
play/convert it. You don't need a script, one command will do it:
find . -name "*.wav" -print -exec oggenc -q 5 {} \;

Re: mp3 vs. ogg...
Several people have written suggesting I use ogg Vorbis
instead of mp3. I really do get that. I'm not into the
whole 'bleed-em-dry-with-a-proprietary-format' routine.
And it is my intention to move toward making my recordings
available in .ogg format as well. And! This little command
line from Jan Depner is *GREAT*! :
find . -name "*.wav" -print -exec oggenc -q
5 {} \;
It does exactly the trick I need for making .ogg files out
of my wav's. Perfect! for ogg...
But I still gotta make mp3's. Why? Because I know who I'm
dealing with. ;-) Most of the people I'm working with are
not all that tech savvy and I know that if given a choice
between playing an mp3 and download/configuring some new
piece of software, they'll either play the mp3 or not at all.
These are my siblings, folks. I really *know* them. Even if
installation is truly easy, they're not gonna do it. But I
want their musical involvement and the .wav files are just
too big, so mp3's it is. For now. Eventually they'll upgrade
when their old 'puterz die or they get too bloated and full
of worms and viruses, and maybe then they'll have something
that plays .ogg files. But until then, I have no intention
of wasting my energy trying to get anyone else to change the
way they do things. (We're quite a stubborn lot. ;-) )
So, I still gotta do the same trick as above somehow for the
mp3's. a couple folks have sent me scripts. cool. I'll
hack through them. But maybe also somebody could explain to
me what the above magic command line is doing so I can
subvert it to my own evil purposes. ;-)
In the meantime, I've incorporated 'Jan's Magic Line' into
my script and voila! I have a bunch of little oggies on
my web site.
By the way, if anyone is interested in hearing my stuff, or
collaborating musically, I'd be willing to talk about that.
Everything is all cheapo demos so far. The recordings are
noisy and my voice sounds whinier than I'd like but hey, at
least I'm not shy. ;-) and now I have all these new Linux
music workstation tools to do *good* recordings with. :-)
My site is here:

The link to the dailies is at the bottom of the front page.
Toodles!

That's fine... just use:
find . -name "*.wav" -print -exec lame --vbr-new -b 80 -B 192 {} {}.mp3
Change -b and -B to suit. They are the minimum and maximum bitrate
respectively. If you want CBR, then replace --vbr-new -b 80 -B 192 with -b
bitrate, the default is 128.
After a bit of time, you'll end up with a whole bunch of MP3s.
Good luck!

Here is a shell script that will make the convertion if the mp3 file
does not exist:
Yo can save it as /usr/bin/wav2mp3 as root. Remember to convert it to
executable with: chmod a+x /usr/bin/wav2mp3
Then you can use the find command as:
find . -name "*.wav" -print -exec wav2mp3 {} \;
