Is there an encoder that i can encode different birates in mp3 pro format?
There’s a choice of bitrates in Nero’s encoder, up to 96/high quality, which produces pretty good results.
Don’t know of any free standing progs - Thompson presumably produce one, since they put out a freebie limited to 64 kbs some time ago. Steinbergs My MP3 Pro sounds promising, but I can’t get the mp3 checkbox to function. I think it’s MP3 Pro rather than mp3pro, if you see what I mean.
As far as I know, a MP3Pro filter is included into CoolEdit Pro 2.0 which allows different bitrates. But it costs a lot of money ;-).
