Hello, is it possible to change the audio quality using ffmpeg?

[REM333]

I read the sticky on the top of this page, and I was able to convert a huge video file (1100kb/sec video, 128kb/sec audio, XviD) to 320x240 D2 size (180kb/sec video), but the audio quality remains at 128kb/sec. Can someone help me by telling me what to write in the .bat file in order to reduce the audio quality to 56kb/sec and to make the sound channel mono? Thanks in advance.

I'm guessing you are using one of the batch files which drive ffmpeg.

You can replace your "-ab" flag value with "56kb" wherever it might exist in the command line. If it doesn't, just add "-ab 56kb" at some point.

As for mono . . . I'm guessing that using "-ac 1" may force use of a single channel in the downmix. Not sure, admittedly (and, I don't have time to test at the moment - sorry).

Ah, thanks it worked. For some reason, when i put the -ab 56 it did not i9nitally work, but when I put the -ac 1, it changed both of the settings.
