how the do i keep my ogg rips at a constant 192kbps? i use -q 6 in the additional command line options (i'm using exact audio copy)..but the bitrates still vary..what's the proper preset for keeping it at 192kbps? thanks guys..i'm a n00b smile.gif

You can't (well...you can probably constrain the high/low swings with some command line option). Ogguser posted image was designed as a VBR format. If your looking for a 192 kbs average then I would encode at -q 5 to -q 6. But it is highly dependent on the material your encoding....the kbs swings are much greater than any other format I've seen, making it much harder to pin down an average rate (but that's one reason it sounds sooooo good smile.gif). Accept no substitutes.

It can be done more or less by specifying the same minimum and maximum bitrate... but why do you want to do that? Ogg Vorbis is a variable bitrate codec by design. It will perform better if you leave bitrate judgement to the encoder rather than confining it to just one specific bitrate. That would be like having a car with just one gear.

i see..thanks guys...i guess i'll just use the nominal, min, max command lines....thanks!

You should just use the -q switch, nothing more. It means that all your music will be encoded with the same quality. So once you find a quality setting you are comfortable with, you can use it for each and every song and never worry about bitrate issues. They will all sound equally well! If I'd use Ogg Vorbis, I'd settle on -q 6.

From the man page it looks like you would set the -managed flag and -b 192 to get CBR 192.
The page recommends it only if you need CBR, as for streaming.
