bulk mp3 bitrate change

hey i just bought a little mp3 player and im trying to cram
as much music on it as possible (without sounding like
shit).

most of my mp3s are 192k. are there any pgms out there that
will drop my quality in bulk so i dont have to re-save each
file one at a time?

Here's what I'd do - load up the files you want in a
playlist in Winamp, then select Nullsoft disk writer as the
output, decode them to wav en masse, then use some drag 'n'
drop tool like RazorLame to re-encode them to 128k.

You will lose some quality this way, but the mp3 spec
doesn't support bitrate-peeling like Ogg Vorbis so I guess
there's no other way.

You can use Wavelab to do Batch processing, I am sure other
audio packages let you do it as well.

I use easy CD-DA extractor 5.0 from www.poikosoft.com to
convert a list of mp3 files to high qual 112kbs (using lame)
you can't tell the diff unless it's metal really. i get
quite a few on my player that way.

yeah, mine's got 64 meg, too. i can fit all of ICBYD on
there at 128 kbps. at best.

i'm also looking to get a memory card for it too.

Easy Audio File Converter (included with CDDA extractor)

download an old version off kazaa so you don't have to worry
about the expiration date. i have ver 4.6.9

i have something called db poweramp music convertor. it
comes with mp3 (lame) and wav, but you can also download
codecs for other formats. i don't know if its any good, but
its what i use and it is free i think.

use a plugin for winamp like lamemp3 writer (i think that's
what it's called) and select a lower bitrate in the
configuration and do as fleet said but without making wav
first

cool edit pro 2. 0 does batch file conversions - this should
be fine for your needs :)

Wah! That's too cool. I installed the file writer Winamp
plugin, told it where my lame.exe was and a few
seconds later I had created a 128k file from a VBR one. Too
cool. I'm gonna use this a lot to downsample the VBR files
from EMusic so I can play them on my mp3 boombox (goddamn
thing won't read VBR files). Thanks! Much more efficient
than making wavs first.

for file in `cat myplaylist.m3u` ; do
> lame --silent --alt-preset cbr 128 $file small-${file}
> done

Even cooler - I didn't realize Lame could take an mp3 as
input. I figured the file writer plugin was sending it a
stream of wav data.
