POWr 3 Noise Shaping : Additional, optimized noise shaping is used, which can extend the dynamic range by 20 dB within the 2—4 kHz range—the range the human ear is most sensitive to.
Note: Noise Shaping minimizes the side effects caused by bit reduction. It does this by moving the quantization noise spectrum to the frequency range above 10 kHz—the range the human ear is least sensitive to. Technically, this process is known as spectral displacement. UV22HR: Allows for the best possible sound resolution when bouncing bit recordings into bit files. Important: Dithering the same audio signal multiple times should be avoided.

Now live: A fully responsive profile. Related 4. Dithering is adding some form of noise shaping when reducing a file from 24 bit to 16 bit. When we get into really low-level signals, like reverb tails, it becomes difficult for digital algorithms to know whether the necessary bits should be turned on or off. The process of rounding off low-level signals to fewer bits creates "quantization noise.
Dithering adds a small amount of very controlled noise to the original signal, so the bits can be made to switch on or off. Mike Robinson "I wanna quit being a computer consultant and become a composer and arranger at age fifty- nevermind.
Mon Mar 27, pm Thanks Mike, I get dither, but it looks like you're not sure either! Mon Mar 27, pm It is merely my understanding that floating-point numbers are used internally throughout the system, because this is assured to give the system sufficient numeric precision to be certain that no data will be lost "in transit" due to insufficient precision.
I believe that "the final set of numbers, which will finally be recorded," is always engineered so that it will fit into the number-space Apple's project-file formats without loss.
When you bounce , of course, it all necessarily depends upon "what file-format are you bouncing to? Tue Mar 28, am The manual doesn't really explain, but does state "Dithering is recommended when bouncing bit recordings into bit files" which suggests you don't need to dither a bit export. Would be nice to get some clarity. I understand that you only dither when truncating, but if a system is bit FP, is exporting to bit a truncation? Tue Mar 28, pm I don't dither when bouncing a mix to a pre-master file 24bit I dither when bounce the mastered file to 16bit I think it's not necessary to dither in the first stage mentioned above.
And as far as I remember a lot of mastering engineers ask you not to do so. Logic Tue Mar 28, pm Joelonsdale wrote: The manual doesn't really explain, but does state "Dithering is recommended when bouncing bit recordings into bit files" which suggests you don't need to dither a bit export.

Some dithering algorithms might as well work as you guys describe, but more often than not dithering is a random spectrally shaped noise added to the signal that operates at least significant bit. It's used to randomize quantization error so when scaling from 16bit to 24bit, two samples that would otherwise end up the same value in 16bit but were not the same value at 24bit essentially are different values at 16bit due to random dither noise.
Technically, since logic However since noise floor of 24bits is well below 30dB any analogue equipment I wouldn't bother dithering at 24bits. Wed Mar 29, am "Technically, since logic However since noise floor of 24bits is well below 30dB any analogue equipment I wouldn't bother dithering at 24bits". That sounds like an answer - the DAW is truncating down to bit but it isn't worth dithering this first truncation
