Re: Easy question about digital audio (last time, I promise ...)

An IEEE-754 format floating-point number has one sign bit, 8 exponent bits, and 23 mantissa bits.

Addendum 2: note that the 24-bit range comes from the "understood 1". Most 32-bit IEEE-754 numbers have an implied 1 bit to the left of the binary point. In a way, this extra bit is contained or "spread across" the exponent bits.

There are more details about this, but I won't bore you with them .. lots of good references on the Net.

OK, I'm done :)
