Convert .flac files into .mp3

In order to convert .flac to .mp3, you'd need to do the following: first cd into the directory with the .flac files, then

for x in *.flac ; do OUTF=`echo "$x" | sed s/\.flac$/.mp3/g` ; flac -c -d "$x" | lame -m j -q 0 -V 0 -s 44.1 - "$OUTF" ; done

Convert .wma files into .mp3

Another thing that's been troubling me regarding audio files is those damn .wma-s that cannot be played by my iPod. So it's time for a handy script that will convert .wma into .mp3:

for x in *.wma ; do mplayer -vo null -vc dummy -af resample=44100 -ao pcm:waveheader "$x" ; lame -m s audiodump.wav -o "${x%wma}mp3" ; rm audiodump.wav ; done

Pretty impressive – lame's manual page deserves a good read.

Convert .m4a files into .mp3

One of the things that's been troubling me lately has been the fact that on a standard Debian/Ubuntu system I can't seem to be able to edit the tags for the .m4a files I have.

So, in order to edit the tags on the .m4a files... I'd rather convert them into .mp3-s. The way to do this is actually simple.
