Hi,
I don't know if I should start a new topic for this - I have found this topic the most suitable to ask.

I have lots of 320 CBR files encoded with LAME Encoder. Is there a way to transcode them into VBR - with the initial file settings (stereo/joint stereo, filters and so on) left untouched - but in a slightly _lossy_ way, without decompressing the whole file?

E.g. I'd like to reach an average reduced bitrate of ~200-220 kbps, where some of the frames that contain high frequencies remain untouched in the transcoded file? (And similarly, mono frames such as bassdrum intros get reduced to whatever bitrate is appropriate for them.)

Is there an option for this in LAME? (Or, is there a 'lossy MP3Packer' available that I don't know of? smile.gif

Thanks!
