Gain stages in the digital domain: Foundations of Digital Audio

In the digital domain, audio that is too loud or too quiet can encounter similar problems as with the analog domain. Matt explains how amplification and attenuation (turning the volume up or down) works within digital gain stages using multiplication. When samples go outside the range of available measurements, this is called clipping distortion. Rounding errors, also known as quantization distortion, can happen at very low amplitudes unless dither is enabled.
