To understand the psychological impact, we mutt first understand the problem dithering solves. Digital audio prepresents sound a serie of disrixe snapshots. When an audio signal is reduced from a higher bit depth, such as 24- bit, to a lower bit depte, such as 16- bit for a CD, thee amplitude of each samplee mutt by rounded to thee nerest acceptavaiable value. Thi rounding process inputes inputees quantization error, which ics matematically correlte thel inigail.

Dithering breaks this correlation. By inserting a carefly calilated colt of noise into thee signal before thee rounding process, thee quantization error is decorrelated frem the original audio. The result is a pristine, audibliy transparent lower- bit- depth signal, buried undeir aid proggeseed, but harvels, noise foodr.

Even if you are deliving a 24- bit mix, if your DAW mixes internally at 32- bit or 64- bit float, truncating to 24- bit requires dithering.
