What actually is 32 bit float? Is it a true 32 bit? Is it better quality than recording at 24 bit?

Sep 10, 2008 12:22 am A 32 bit float is a 23 bit mantissa, with an 8 bit exponent, and 1 sign bit.
It's not any better quality as far as recording goes, but when processing the tracks with effects etc, the accumulated rounding errors that occur with integer based operations are greatly reduced, since only the final result needs to be rounded up/down with FP.
Also as far as recording/playback, no audio interfaces I'm aware of actually record/playback in 32bit FP this all takes place in the software you use, so it doesn't really matter whether you select to record in 32bit FP, the conversion can and usually is done by default in most DAW software these days, except ProTools which still works soley in 24/32 bit integer as far as I know.

Sep 10, 2008 11:19 am yes, it's more gooder in 32 FP, but it may or may not be used in your system at certain points :-)
