| The physical and human spects dealing with audio, video, and images
Vision and color perception: objectively describing color · the eyes and the brain · physics, numbers, and (non)linearity · color spaces · references, links, and unsorted stuff
Image: file formats · image processing
Video: format notes · encoding notes · On display speed
Audio physics and physiology: Basic sound physics · Human hearing, psychoacoustics · Descriptions used for sound and music
Digital sound and processing: capture, storage, reproduction · programming and codescs · some glossary · Audio and signal processing - unsorted stuff
Electronic music: Some history, ways of making noises · Gaming synth · on latency ··· microphones · studio and stage notes ·

Music electronics:
device voltage and impedance, audio and otherwise ·
amps and speakers ·
basic audio hacks ·
Simple ADCs and DACs ·

multichannel and surround ·
Noise stuff: Stray signals and noise · sound-related noise names · electronic non-coupled noise names · electronic coupled noise · ground loop · strategies to avoid coupled noise · Sampling, reproduction, and transmission distortions · (tape) noise reduction
Unsorted: Visuals DIY · Signal analysis, modeling, processing (some audio, some more generic) · Music fingerprinting and identification
