[FFmpeg-user] Looking to change QT audio files from 4 mono chanels to 4 discrete chanels

Hello All,

I'm looking for help.

I have a set of QT files with 4 audio mono chanels (uncompressed 48kHz).
I need to turn these files into 4 discrete audio chanels.

This can be done manually into QT7 (but it's quite long to change each chanel of each file).

I wonder if ffmpeg could do this, without recoding the video or the audio.

Any help appreciated.
Thanks in advance
