[cameron20020]

hi, any apps i can use for this?

You need faad2 and lame installed.

$ faad foobar.m4a       # to convert to wav
$ lame foobar.wav foobar.mp3          # to convert to mp3

Thanks for the tip, but here is all I get, no matter which m4a file I try:

----------------
jim@mk8-939a-1:/mnt/data1FAT32/tempFromAV/Bob Marley$ faad War.m4a war.mp3

Thanks for any help.

$ lame foobar.wav foobar.mp3          # to convert to mp3

Works like a charm! Is there a way to convert multiple files at once?

Here is a script that I have had for a long time to convert mp3 and wma files to ogg. I have modified it for m4a files here:

#!/bin/bash
#for i in *.wma ; do 

current_directory=$( pwd )

#remove spaces
for i in *.[Mm]4[Aa]; do mv "$i" `echo $i | tr ' ' '_'`; done

#remove uppercase
for i in *.[Mm]4[Aa]; do mv "$i" `echo $i | tr '[A-Z]' '[a-z]'`; done

#ripping with mplayer
echo Processing file: $i 
#for i in *.mp3 ; do mplayer -vo null -vc dummy -ao pcm:file=$i.wav $i; done
for i in *.m4a ; do faad $i; done

#Convert to OGG
oggenc *.wav;

#removing old file
rm *.wav;
#rm *.m4a

You can also change the line 'oggenc *.wav;' to 'lame *.wav;' to convert to mp3 rather than ogg.

Perfect! Thanks!
