Hi

For my scripts (Windows) I am looking for one or two free command line tools which can simply convert a wma or m4a/mp4 file to a wav file.

wm8eutil can't decode obviously. :-(

Is there something without big overhead and no GUI?

For m4a files you can do:

• Go to http://www.rarewares.org/aac-decoders.php
• Download FAAD 2 for Win32
• Extract faad.exe
• Start --> Run --> cmd
• faad.exe infile.m4a

For wma files:

• Download ffmpeg
• ffmpeg -i infile.wma -acodec pcm_s16le -ar 44100 -ac 2 -f wav outfile.wav

or:

• Download MPlayer
• mplayer -vo null -vc dummy -af resample=44100 -ao pcm:waveheader:file="outfile.wav" "infile.wma"

Thanks for FAAD. Just as I need it but ffmpeg (8MB) and mplayer (11MB) are way to big for this little job. Is there no smarter solution, smaller exe?

Googleing wma2wav gives this:

http://www.stud.uni-karlsruhe.de/~ua7i/wma2wav/

Assuming its the same as the wma2wav source code I have on my unix box, its based on a 4 year old checkout of ffmpeg that only has the asf parser and wma decoder, so it won't be perfect, but generally quite good.

Thank you Mike! This forum is just awesome!

there is another wma2wav written by the guy who did the original xmms-wma plugin here:
