besweet feature request: "convert to mono"-switch

[E-Male]

i often see dual-mono ac3 tracks on dvds
i always want those converted to mono when encoding them to mp3,ogg,aac,... (i think everyone agrees)
i would be nice to have a -mono switch in besweet, that independently from anything else converts stereo sources to mono

[DSPguru]

it would indeed be nice.
currently, there's only support for mono mp2,mp3 & waves.

does that mean this feature might find it's way into an upcoming version of besweet in the not to far future?

In case with mp3 encoding there are 2 switches in Lame:

-m m
stereo mode mono
The input will be encoded as a mono signal. If it was a stereo signal, it will be downsampled to mono. The downmix is calculated as the sum of the left and right channel, attenuated by 6 dB.

-a
downmix
Mix the stereo input file to mono and encode as mono.
The downmix is calculated as the sum of the left and right channel, attenuated by 6 dB.
This option is only needed in the case of raw PCM stereo input (because LAME cannot determine the number of channels in the input file).
To encode a stereo PCM input file as mono, use "lame -m s -a".
For WAV and AIFF input files, using "-m m" will always produce a mono .mp3 file from both mono and stereo input.

In case with aac encoding there is option in Nero configuration that downmix to mono.

I don't know about ogg.

And I vote for mono switch in besweet too. :)
