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
· noise reduction
· halftoning, dithering
· illuminant correction
· Image descriptors
· Reverse image search
· image feature and contour detection
· OCR
· Image - unsorted
Video: format notes · encoding notes · On display speed · Screen tearing and vsync
Audio physics and physiology: Sound physics and some human psychoacoustics · Descriptions used for sound and music
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
Digital sound and processing:
capture, storage, reproduction · on APIs (and latency) · programming and codecs · some glossary · Audio and signal processing - unsorted stuff
Music electronics:
device voltage and impedance, audio and otherwise ·

sync
Electronic music:
- Electronic music - musical terms
- MIDI · Some history, ways of making noises · Gaming synth · microcontroller synth
- Modular synth (eurorack, mostly):

Ordered dithering
Ordered dithering uses regular patterns to imitate gradients.
This will often have noticeable grid and/or crosshatch patterns.
