Min MP3 compression ratio

Does MP3 allow uncompressed audio to be stored with 1:1 ratio ?

Kind regards,

No. Mpeg 1 Layer 3 specifies the max. bitrate of 320kbps.

yes, that's the right term, "max bitrate"

You should keep in mind that Layer 2 audio performs better at that high 
bitrates than Layer 3. So in general at 256kbps and above, Mpeg 1 Layer 
2 is the better choice. At 384kbps the same applies to Layer 2 versus 
Layer 1. The latter is nearly lossless in the most cases.
