MP3 - maximum sample rate and bit depth

what is the maximum sampling rate and bit depth supported by MP3, can someone tell me?

(and when i say "bit depth", i of course don't mean "bit rate")

AFAIK the official MPEG standard for mp3 indicates support for 22k, 32k, 44.1k, and 48k sampling rates. Extensions allowed for lower sampling rates, but, I do not believe it supports higher sampling rates. Regarding bit depth, the mp3 encoders I've used produce identical-size files whether I provide a 24 or a 16 bit file. So I assume that there is some form of truncation necessary, meaning that the standard is fixed at 16 bit.

There was a thread about this a while ago, and somebody said that mp3 uses float internally. So I guess that 24bit are not simply truncated by the coder but I don't expect you to hear any difference.
