Converting flac to mp3

By Cèbe, . Permalink Ubuntu

Note that you will need flac and lame for this to work. Run the following line in the directory where the flac files are:

for file in *.flac; do flac -cd “$file” | lame -h – “${file%.flac}.mp3″; done

You can also make lame create the mp3 files somewhere else. Take the following line:

for file in *.flac; do flac -cd “$file” | lame -h – YOURLOCATION/”${file%.flac}.mp3″; done

A little bash (with some extra features such as preversing the meta tags)

#!/bin/bash

if $# -ne 1
then
  echo "Usage: `basename $0` sourcePath"
  exit 65
fi

SOURCEPATH=${1%/}
TARGETPATH=${1%/}.mp3
FINDEXT=".flac"
IFS=$'^'
TEMPIMAGE=${1%/}.mp3/${1%/}.jpg

echo "Ready to convert all flac in source path $SOURCEPATH to mp3 in target path $TARGETPATH"

echo "Do you want to continue ? (y/n)"
read ans
$ans != "y" && sleep 2 && exit 0


find $SOURCEPATH -type d -exec mkdir -p $TARGETPATH/{} \;

find $SOURCEPATH -type f -name *$FINDEXT | while read file
do
  ARTIST=$(metaflac "$file" --show-tag=ARTIST | sed s/.*=//g)
  TITLE=$(metaflac "$file" --show-tag=TITLE | sed s/.*=//g)
  ALBUM=$(metaflac "$file" --show-tag=ALBUM | sed s/.*=//g)
  GENRE=$(metaflac "$file" --show-tag=GENRE | sed s/.*=//g)

  DATE=$(metaflac "$file" --show-tag=DATE | sed s/.*=//g  | cut -d "-" -f 1)
  metaflac "$file" --export-picture-to=${TEMPIMAGE}  
  outputFile="$TARGETPATH/${file%.flac}.mp3"
  
  flac -cd "$file" | lame -h -b 192 - $outputFile  
  /usr/local/bin/eyeD3 -t "$TITLE" -n "${TRACKNUMBER:-0}" -a "$ARTIST" -A "$ALBUM" add-image ${TEMPIMAGE}:FRONT_COVER encoding utf16 remove-all to-v2.3 "$outputFile"
  #fixes Date and Genre (buggy in eyeD3)
  id3v2 -2 -y "$DATE" -g "${GENRE:-12}" "$outputFile"
  rm ${TEMPIMAGE}
done
