Hello all,
I'm trying to create 6 32-bit mono wav files from an ac3 using Besweet. Everything was going fine, until one source gave me this:
BeSweet -core( -input "input.AC3" -output "output-" -6chfloat )

I was trying to get a straight rip without any downmixing, so this obviously surprised me. After looking though the command line switches, I tried making sure there was no downmixing happening, and I came up with this.

The overflow values are exactly the same. Does anyone have any idea what's wrong here? I'm just trying to rip the tracks exactly as they are encoded, so I don't see how they can possibly overflow by .5db. (Then again, I really don't know much about the whole Ac3 format.)
Thanks,
