--alt-preset - how without bitrates below 128kbps?


what I have to write if I want tell "Lame" with its --alt-preset 128 parameter that it should not go to use a bitrate below 128kbps?
I have worked at the Lethal Weapon 1 sound with --alt-preset 128 and I get a VBR with 96kbps sometimes, but that's not what I want

You are talking about 2 different things here yosemite. --alt-preset 128 makes an ABR mp3 with average bitrate of 128.

If you want a MINIMUM frame size of 128 you need to specify that with a '-b 128' but obviously that won't work with an ABR 128.

Maybe what you want is a '--alt-preset standard' which will give you about 160-180 kbps for a movie soundtrack...and it uses '-b 128.'

You could also try something like --alt-preset 160 -b 128 to give more control over the final file size.

You might as well use --alt-preset cbr 128

Not allowing ABR 128 to use frames below 128kbps defeats the purpose of ABR.
