| kinda wondering...
what happens when one dithers a (legal) 32-Bit FP file all the way down to 16-Bit w/ their favorite dither box ??
reason I ask is...I'd been used to (like everyone else, I suppose) bouncing out of the DAW (SONAR) at 32-Bit FP...then brick walling to legal in the mastering rig (WaveLab) & rendering to 24-Bit at the same time...then dithering (UV22HR) & rendering to 16-Bit ftom 24.
[i had been doing this 'cause I assumed (& had heard) that A) the quantization error from 32 > 24 is miniscule & well below the audible range & B) it's a legal file after limiting anyway so I may as well render to 24...why waste bits.]
I did one today whereby I kept the file size/format at 32-Bit FP during the brick wall phase...& then dithered all the way down to 16 from 32 as the final stage...& it sounded audibly way better (in comparing both methods) to the old method (24 > 16).
most notable was a more accurate reproduction of transients (snare, cymbal crashes, et al.) [i had used elephant 2 on clip for the limiting phase].
guess I'll keep this new (new to me, that is) method...but I'm wondering what's goin on technically w/ it ?
