Re: OT: 24Bit/96Khz vs 16Bit/ 44.1Khz recording

[Charles Zwicky <cazwicky@earthlink.net>]

Bit depth is independent of sample rate. 
The bit depth simply determines the number of discreet amplitude levels 
which can be quantified at each sample. The number is expressed as an 
exponent of 2 (because each bit is binary - a 1 or a 0).  16 bits = 2^16 = 
16,535 amplitude values, 24 bits = 2^24
=16,777,216...!
