What is a VJ?
VJ (visual jockey) is the role — and the system — that picks, layers, and changes visuals in sync with music. Clubs, festivals, and live venues use VJs to add a visual layer on top of the DJ's audio.
Historically VJ meant "a human mixing visuals live." Today the term extends to automated and unattended workflows where pre-built rules or song recognition swap visuals for you. This guide maps those variants and explains how to choose between them.

Tech and tools
From free (Hydra, TouchDesigner NC) to pro (Arena, Notch, disguise).

WebGL, Three.js, p5.js, Hydra, ISF — the lineage. A technical primer.
Shazam, ACRCloud, AudD — differences, and the role in automated VJ.
FFT, BPM, onset detection, and LFOs — the five signal-processing ideas.
Practice, operations, material, and rights
PC, GPU, HDMI, MIDI — three tiers at roughly US$400, $1,000, $2,000.
Layer design, color temperature by genre, lyric treatment — the visual side.
