[NTLUG:Discuss] converting audio files via CLI tools

[terry]

To convert a batch of MP3s to WAVs using lame:
=========================================
     (First, fix the filenames)
If they have uppercase extensions - change to lowercase:
 for i in *.[Mm][Pp]3; do mv "$i" `echo $i | tr '[A-Z]' '[a-z]'`; done
To convert just extensions:
 for i in *.MP3; do mv "$i" "`basename "$i" .MP3`.mp3"; done
If there are spaces, remove those first:
 for i in *.mp3; do mv "$i" `echo $i | tr ' ' '_'`; done
Now to convert mp3s to wav:
 for i in *.mp3; do lame --decode "$i" "`basename "$i" .mp3`".wav; done
