Loop Room
Procedural background music. 19 moods, zero copyright strikes.
Seamless CC0 music loops generated in your browser with pure Web Audio synthesis — no samples, no AI, no licensing fine print. Pick a mood, roll the seed, export stems, MP3s, or a timed track with fades.
Free web app
FX Bench
61 sound effects, synthesized live. Download the WAV, not a licence.
Sound effects generated in your browser from oscillators, filtered noise, and envelopes the moment you hit play — no samples, no AI, no licensing fine print. 79 effects across 11 categories, from impacts and whooshes to sad trombones. Tap a pad, watch it on the scope, then pull a full-quality WAV — or grab the whole library as a zip.
Free web app
Transition Bin
574 free video transitions, drawn by maths in your browser.
Transition packs cost money and lock you to one colour. These are generated on your device instead — 43 styles from hard wipes to glass shatter, paint drips and halftone sweeps, in any colour, speed and resolution you like. Scrub it frame by frame, then export as green screen, luma matte, transparent MOV or plain colour. No account, no uploads, no AI.
