I have downloaded and unzipped. Each ac3 file is about 4 seconds, that's fine for burning waves to CDDA with Nero, as Nero has a limit of 2 seconds per wave.

Yeah,

I confirm that surround (rear) left and surround (rear) right channels are separated.

It seems after some testing, that plugin works fine.

The separation is probably the same as got by DS2 of headac3he0.23.


umm, why have I not been able to hear it some time earlier ?!
Perhaps some errors in my command line....


The working line you can find in logfile:

One example:

d:own filesmoviesprogramsBeSweet ac3 to mp2

BeSweet.exe -core( -input d:own filesMy MusicAC3tests 5.11 channel ac3sl.ac3 -output d:own filesMy MusicAC3tests 5.1sl.wav -2ch -logfile D:own filesmoviesprogramsBeSweet ac3 to mp2BeSweet.log ) -plugin( -name BS_Downmix.dll -func NoLFE -6ch -azid( -s surround -L 0db -S 0db --maximize ) -ssrc( --rate 44100 --twopass )
