layer1 (1:4) is 384kbit/s.#
This is the highest as far as I know.
Do you want higher? Why?
Does anyone offer software to compress SACD or Digital Audio CD
from 192Ksample/sec 24bit down maybe 10 times?
A high quality MP3HR (hi rate) that might just be better than 16bit CD.

mp3 (mpeg1 layer3) is limited to 320kbps, just for portability reason.
mp2 (mpeg1 layer2) - 384kbps.
mp1 (mpeg1 layer1) - 448kbps.

For 384kbps compression, you can use mp2 encoders, builded into video-related compression software like TMPGEN or ToolLAME. Process only audio stream, of course. You get output file with *.mp2 extension. Just rename it to *.mp3 - it playable on most software players (WinAmp for example) and recognizable with most of mp3-related software (for tagging or browsing or something else). Unfortunetely, onle few hardware players are capable to deal with mp2-stream, so using mp2 is limited to computer.
As for quality - 384 sounds virtually identical to 320 (with 20% apprx. rise in file size).

Remember, that gap between mp3/320 and uncompressed audio can be filled with lossless codecs like FLAC or APE.

just save the uncompressed WAV file - 1500kbit and no compression artifacts. Why bother with mp3 if 320 isn't good enough for your application?

space issue? go with FLAC or similar lossless compression and you can get about 700kbit/sec without any compression losses.

Ditch MP3 and use MusePack - - if you want an excellent high bitrate lossy codec. I wont accept anything lossy now unless it's MPC.
