Audio synthesis workbench

FX Bench

Every sound below is generated from raw waveforms — oscillators, filtered noise, and envelopes — the moment you press play. No samples, no AI generation, nothing to license. Play it, then pull the WAV straight into your edit.

Free, and staying free.

No account, no watermark, no sound pack to buy. If FX Bench saved you a subscription, you can put a coffee toward the next free tool — completely optional, and the whole library works either way.
