What does dithering do in logic?
What does dithering do in logic?
Without getting too heavily into the maths, dithering is a process which enables us to move from one bit depth to another without losing too much fidelity. Often audio recorded and produced within Logic is 24 bit, this audio will need to be reduced to 16 bit for distribution, this is where dithering comes in.
Should I enable dithering?
If you’re going from 32-bit fixed point (not floating point) to 24- or 16-bit, you should dither. However, if you’re bouncing your mix to a data-compression codec like MP3 or AAC, dithering is not necessary. Only dither when you render your audio to a lower bit-depth. Don’t dither before converting to MP3 or AAC.
Does logic automatically dither?
Inside Logic, audio is processed in a 32 bit floating point format although you are still hearing a 24 bit signal out of your interface. The extra 8 bits do not contain audio data so there is no need to dither.
Is dithering good or bad?
Dithering is best left for the mastering process. This means that whenever a higher bit depth file is reduced to a lower bit depth file, dithering should be used to mask the effects of quantization distortion. The most common time this happens during post-production is during the mastering process.
What is the best dithering algorithm?
Break that graph down for me a little.
| Dither Algorithm | Noise Reduction | Highest Peak |
|---|---|---|
| Goodhertz “High” | 8 dB | 24 dB |
| POW-R #3 | 7 dB | 27 dB |
| FabFilter Pro-L “Weighted” | 7 dB | 27 dB |
| Goodhertz “Optimal” | 6 dB | 16 dB |
What is the main advantage of dithering?
Benefits of Dithering. Dithering can reduce the effects of pixel-to-pixel errors in the flatfield or spatially varying detector sensitivity. Integer shifts of a few pixels allow the removal of small scale detector defects such as hot pixels, bad columns, and charge traps from the image.
Should I dither my song?
Always use dither when saving out to 16 or 24-bit files. So a better rule would be: Always dither – unless you’re staying at 32-bit floating point, in which case once is enough. So when you’re saving out at 16 or 24-bit before mastering a file, especially more than once, correct dithering is essential.
Which is the best resolution for dithering in audio?
Turns out most everyone is just fine at a 16 bit resolution, as seen in the middle image above. The one on the right is 24 bit resolution, and can tell there’s more samples being taken. The more samples we take, like up to a 32 bit resolution, the closer we get to emulating reality.

What is dithering in audio and what does it do?
Dithering is a process to smooth out those errors. It’s not easy to hear in audio form so my examples will be with images and you can translate that analogy mentally to digital audio and you’ll understand it nearly immediately. Let’s look at some definitions of this term and we’ll see why people are confused.
How many bits per sample do you need for dithering?
In the context of dithering, it is in the “bits per sample” that we’re interested. So, better dynamic resolution is pretty easy to get on your PC; just use more bits per sample. Get a 24-bit A/D converter; mix and edit at 32 bits; process effects at 64 bits. End of story. Except… audio CDs are 16-bit.
