I know, this must seem a bit strange, but I want to get CBR 320kbps mp3 files, but when I use:

lame.exe -m j -q 0 -b 320 -cbr

lame says (and does) only encode in 128 kbps CBR. What's wrong with my params? Thanks a lot!

PS: I know I could use --preset insane, I tried it and it got me 320kbps, so it worked, but I'd like to find the error above ....

There's no -cbr switch. Only --cbr.

As lvqcl said, -cbr is not a valid option. It should be --cbr. Probably the invalid string makes lame to use the default, 128 kbps, bitrate.

However, the recommended setting is the plain -b 320 without any other switches (in recent LAME encoders --preset insane = -b 320)

Thanks for your help guys. My GUI was using the --cbr switch with only one dash then.

So

-m j -q 0 -b 320 --cbr

is exactly the same as

-m j -q 0 --preset insane

?
