Hi,

I've got a 4 channel wav file.. that I wish to encode into a 4 channel (or quadraphonic) AAC file... there's no centre channel and no LFE. I'm using faac 1.24 on Linux (Ubuntu)

I started with:

faac -q 100 -P -o warbirds.mp4 jlwarbirds.wav

but this gives me a lot of noise when played back in VLC. Then I tried explicitley setting the bit size, smaple rate and channel count ...

faac -q 100 -B 32 -R 44100 -C 4 -o warbirds.mp4 jlwarbirds.wav

but this still gives me mostly noise .. and says "Remapping input channels: Center=3, LFE=4" which I dont want. So I tried:

faac -q 100 -I 0,0 -B 32 -R 44100 -C 4 -o warbirds.mp4 jlwarbirds.wav

which also gave me noise .... can anyone see if my params are wrong?
