View Full Version : BeSweet mono problem

I usually encode to a mono mp3 when the stereo separation is less than 1%, so I tried this on one such AC3 using BeSweet and ended up with a file twice the length(time) than the joint stereo(correct) version. I thought this was because i was using SSRC downsampling, but disabling this still resulted in the extra long file. When playing the mono mp3, it sounds indeed like everything is slowed down to half-speed(kinda cool ;) , but definately not what I wanted) I'm wondering if anyone else has had trouble with mono and BeSweet, and if perhaps downmixing (in AZID) to a single channel might be the solution...-m mono i believe under -azid( ) I'm at work now, or else I'd try this

On a similar note, any chance of getting the final LAME lines to show up in BeSweet(the ones with average bitrate and stereo information)?

not a problem, just not supported ;)
i once asked people if they would be interested in support for mono-mp3s and hardly got replies.

sorry, i must have missed that question. The reason I do it is to save space of course. A mono mp3 is always smaller than a joint stereo mp3, even when no frames are encoded as stereo frames.

...now this would be a marvel...
BeSweet encodes a file and sees that the file has < 1.0% stereo separation and then reencodes with the same settings except in mono mode....and shows the average bitrate :)
