Highest possible bitrate?

Hi, was having a 'discussion' with someone the other day about the quality of MP3's etc, and Kbps came up.

The highest i've seen is 320kbps, but this lad reckons you can, especially in studios record at over 1000kbps, is that true?

Cheers.

320kbps MP3 CBR is the maximum, but 1000kbps is roughly lossless/flac. Unless he's talking about higher sampling rate/frequency (ie 10hz-120khz, 192khz)

So 320 is the highest you can have on MP3, but you can get higher on cd or other format.

Puts the argument in limbo really.

you can go higher than 320k with mp3 but it breaks support and as such isnt recommended. Regardless, its a little overkill. if you're talking purely about data throughput and not formats (uncompress, mp3, flac ect) than there's no limit to what they can use, really.

a cd has a bitrate of ~1411kbps. 16bit samples, 44.1khz sampling, 2 channels - 16x44.1x2 = 1411.2kbps

if a studio is mastering 2 channel uncompressed audio @ 192khz / 24bit they are pumping through 9984kpbs, or 9.75mb/sec.
