SEGAN

A free, open-source AI sound effect generator

SEGAN doesn't generate sound with an audio model. Your AI agent writes it in SEGAN's notation and SEGAN synthesizes it, which is why the sounds match each other, loop cleanly and cost nothing.

Free forever: MIT-licensed, runs offline on your machine. No credits, no subscription, no API key.
Consistent: one shared mix, room and loudness targets for every sound in the game.
Editable: the sound is text in your repo. Change one line and rebuild; review changes like code.
Game-ready: WAVs with loop points, variations, phases, stems, manifest.json for any engine, Godot resources.
Honest about limits: synth only (chiptune, 80s synth). For realistic or orchestral audio, use a sample library or a generator.
