Simplest method I found that also changes extension to mp3:

for i in *.wav; do lame –preset standard “$i” “${i/%wav/mp3}”; done

This script works best for me:

#!/bin/bash
LAMEOPTS=”-h -V 0″ #change your lame settings here

for FILE in *.wav ; do
OUTNAME=`basename “$FILE” .wav`.mp3
lame $LAMEOPTS “$FILE” “$OUTNAME”
rm “$FILE”
done

My solution for the .wav.mp3 problem…

for f in *.wav ; do lame -h $f `echo $f | cut -d. -f1`.mp3 ; done

Hello, this command that will convert all .wav files in a folder and put the right .mp3 extension instead of .wav or .wav.mp3 :

$ for f in *.wav ; do NEWNAME=`echo “$f” | sed ‘s/.wav/.mp3/g’` ; lame “$f” “$NEWNAME”; done

Thanks very much! I was looking for a solution to batch converting an album to a new folder.

In the end I used the following two lines:
$ mkdir new
$ for f in *.mp3 ; do lame –preset standard “$f” “new/$f” ; done

Well people are still commenting on this page :)
I was looking for something and stumbled across this page again so I find it worth mentioning that a couple of days after I last commented here I found a WAY BETTER solution for this problem.

1. Install shntool. It’s a wonderful tool for a lot of things. http://etree.org/shnutils/shntool/

2. export the following:

export ST_CUST_ENC=’ext=mp3 lame -V 0 -q 0 –vbr-new –noreplaygain – %f’

You can put the above line in your .bashrc (remember to source .bashrc to continue using same terminal for current session). Modify lame options as per your needs, look man for more info.

3. run the following command to convert all your wav to mp3

shnconv -o cust *.wav

If you have single wav file an album and a cue file, use:

cuebreakpoints album.cue | shnsplit -o cust album.wav

cuetools is another utility.

You can do all sort of conversion with shntool. I prefer using picard (search musicbrainz picard) for tagging because I am paranoid about keeping my music arranged and well tagged.

By the way, your syntax was messed up by my websites auto-formatting. So I edited your post so that it shows proper syntax highlighting and fixed the text where my site messed it up. Thanks again.

@gmendoza: Any time mate. Hope you like it, it’s my first bash script ever. (=

Heh, maybe my script was a bit overkill then. I made one for running after a whole cd has been ripped with cdparanoia, and assuming cdparanoia’s default output file names ‘trackXX.cdda.wav”, ‘XX’ being the tracknumbers.

#!/bin/bash
 
TRK="track"
SFX=".cdda.wav"
NUM="1"
 
while [ -f "$TRK"`printf "%02d" $NUM`"$SFX" ]
do
echo "Found "$TRK"`printf "%02d" $NUM`"$SFX", encoding…"
lame -V2 –tn $NUM –id3v2-only "$TRK"`printf "%02d" $NUM`"$SFX" "$TRK"`printf "%02d" $NUM`.mp3
NUM=$[$NUM+1]
done
 
echo "Finished encoding all files."
echo "Deleting wav’s…"
rm -rf *.cdda.wav
echo "…done"
 
exit 0

can any one tell how to convert mp3 to rm?

By: Vyvyan

Vyvyan — Sun, 31 Aug 2008 16:24:43 +0000

for file in *.flac; do lame -q 0 -v –vbr-new –noreplaygain –id3v2-only “$file” “${file%.wav}.mp3″; done

In the last command I told I just echoed the filenames. Here is the complete command. :)

So far, I have been following to automatically remove ‘.wav’ from mp3 files.
for file in *.wav; do echo “${file%.wav}.mp3″; done

To remove wav’s later after the conversion is completed without any errors and with satisfaction is a good idea rather than deleting in same long one line command.

rm -rf *.wav

It isn’t much of an effort. :P

this has inspired me to write this script, it the first time I’ve written a bash script, so I’m sure it could be improved:

#!/bin/bash
TARGET_DIR=”ipod/”
mkdir -p $TARGET_DIR
for f in *.mp3 ; do
fn=${f%*.mp3}”_pod.mp3″
lame -b 96 “$f” “$fn”
mv “$fn” $TARGET_DIR/
done

this resamples mp3′s to 96kbps, this is for my ipod shuffle. It renames as _ipod.mp3, creates an ipod folder and moves the resampled file to it.

Cheers
