I can't see any command to make a 4 channels WAV with BeSweet...
edit: with some weird method I somehow able to do it:
- convert AC3 file to 6 WAV files (with BeSweet)
- I don't know why, but it converted LFE to side right AND left and create empty LFE channel file
- so I renamed side right to LFE, and LFE to side right and left
- merged the 6 WAV files to one WAV file (with BeSweet)
- convert with Nero AAC Encoder
- and I got a 5.1 AAC with silent SR/SL channels and correct FR/FL/C/LFE channels
comments?
