Dithering

• Audio engineers use a process called dithering to resolve quantization errors. Dithering is adding low-level noise into your audio signal to soften unpleasant sounds caused by processing (ex: fade in/fade out).
• Quantization occurs when frequencies are divided up into bits.
• When working with bit depth you’ll encounter quantization errors. These errors occur when a bit falls out of order between frequencies, causing unwanted noise.

Pro Tip: If you are handing your recording off to a mastering engineer, let them do the dithering. If you are mastering your own audio, apply dithering at the end of your processing to reduce noise.
