Convert m4a to ogg

EdTech

How to convert multiple m4a audio files in one directory to ogg format in UbuntuLinux? That’s the question that got me started down this road.

I was hoping for an easy way to do multiple files using FFMPEG but I don’t understand the command line structure well enough. In the meantime, I ran across this script that does the job.

  1. Install faad and lame with the command - sudo apt-get install faad lame

  2. Copy-n-paste the script and save it as m4a2mp3.sh in your /home/usrdirectory
    (e.g. /home/mg)

  3. Make the script executable with this command - sudo chmod 777 m4a2mp3.sh

  4. Switch to the directory and call the script with /home/m4a2mp3.sh

(Note: If you find an error in these instructions, please let me know! Thx in advance!)

#!/bin/bash#for i in *.wma ; docurrent_directory=$( pwd )#remove spacesfor i in *.[Mm]4[Aa]; do mv "$i" `echo $i | tr ' ' '_'`; done#remove uppercasefor i in *.[Mm]4[Aa]; do mv "$i" `echo $i | tr '[A-Z]' '[a-z]'`; done#ripping with mplayerecho Processing file: $i#for i in *.mp3 ; do mplayer -vo null -vc dummy -ao pcm:file=$i.wav $i; donefor i in *.m4a ; do faad $i; done#Convert to OGGoggenc *.wav;#removing old filerm *.wav;#rm *.m4a

How would one do this for multiple files with FFMPEG?
