LAME woes

[Michael Zacherl.]

I found this thread, proposing a command setting (-r -x --bitdepth 24) which should work - but it doesn't - at least not on Mac OS X.

http://www.hydrogenaudio.org/forums/lofiversion/index.php/t37872.html

Another post in this thread mentiones LAME versions which are linked against libsndfile which should be able to handle additional file formats.
Then again I only found versions for Windows which are able to encode FLAC and ogg - no AIFF.
I'm not sure if I want to switch my workflow to WAV - my idea is to improve quality and simplyfy things.

Any idea how to approach/solve this?

Thanks, Michael.

PS: Funnily enough I noticed that the preset setting "insane" sets the quality level (-q) to "3" and not to "0" as the name would suggest. :-)
