As far as I am concerned we can stop the OT section here...

After spending most part of last night doing more tests with long 6-ch audio files which will create temp WAV files > 4GB I think I will put this to rest.

The problem is SoX. This is an essential part of my normalizing routines, I cannot give up using it. And whatever I do trying to get SoX output into FFmpeg, be it through piping to STDOUT or using temp files, it always crashes using 32-bit sources after about 30 min duration. Piping SoX output to Aften works like a charm.

I also think giving up Aften for FFmpeg is not worth the trouble. I did a few listening tests with high quality headphones using AC3 224 kbps stereo files created with Aften and FFmpeg (all default parameters). I could not hear any differences, regardless of the sources.

Still I wonder why noone made the effort to port the FFmpeg AC3 improvements over to Aften...
