Converting Flac to MP3, preserve tags

August 2, 2009

The script converts one flac file to an mp3 file and takes the flac file as a parameter. Do not forget to quote the filename if it contains spaces. Thanks for the tip, Fredric!

#!/bin/bash
FLAC=$1
MP3="${FLAC%.flac}.mp3"
[ -r "$FLAC" ] || { echo can not read file \"$FLAC\" >&1 ; exit 1 ; } ;
metaflac --export-tags-to=- "$FLAC" | sed 's/=\(.*\)/="\1"/' >tmp.tmp
cat tmp.tmp
. ./tmp.tmp
rm tmp.tmp
flac -dc "$FLAC" | lame -b 192 -h --tt "$Title" \
--tn "$Tracknumber" \
--tg "$Genre" \
--ty "$Date" \
--ta "$Artist" \
--tl "$Album" \
--add-id3v2 \
- "$MP3"
