Error diffusion is a dithering technique that distributes quantization error to surrounding unprocessed pixels as it proceeds, allowing smooth brightness gradients even with a limited number of tonal levels. Unlike threshold-matrix methods, it tends to produce a more natural, noise-like texture.

In sound visualization and acoustic analysis, RMS (Root Mean Square) is a highly important metric. Unlike instantaneous peak values, RMS takes the average of amplitudes over a certain time window (buffer size), which enables a more natural and perceptual representation of dynamics, loudness, and visualizations of audio signals.
