About SFX Engine

SFX Engine generates custom sound effects from a text description, aimed at audio producers, video editors, game developers, filmmakers and podcasters who have all lost an afternoon to a library that did not contain the sound they needed. You describe it — a thunderstorm with rolling thunder and heavy rain, a rooster crowing on a rustic farm, a large wave crashing on a beach, a faucet dripping in an empty room — set the length, and generate as many variations as you want, refining the description until one lands. Because every result is generated rather than licensed from a catalogue, the search-for-it problem is replaced with a describe-it problem, which is the right trade for anything specific. Commercial use is included by default on everything generated, with no royalties and no per-use clearance, which is the clause that actually decides whether a tool is usable in client work. Background music creation sits alongside the sound effects, along with a stem splitter and music transitions, and full API access is on every paid tier including the entry plan, so it can sit inside a production pipeline rather than only a browser tab. Named users include Wildlife Studios, RingCentral and the Art Institute of Chicago. Credits are the unit and plans are annual-discounted.
