Sound effects from a sentence

SFX v3 is built around SFX v3, the newest sound effects model in the Sound Effects API. Describe the sound you need and generate it in the browser, or call the API from your own product. Our aim is to make it simple to go from an idea to a usable sound, without searching through sound libraries.

SFX v3 is designed for AI creators, content creators, developers, SaaS founders and teams that need to add AI audio generation to their products. Available models, input options and credit costs are shown in the creation tools.

What you can do

AI audio generation: create sound effects, ambience, foley, vocals and music cues from a text prompt.
Multi-event scenes: describe several events in the order they should happen, for example “footsteps on gravel, then a metallic door opens.”
AI audio generation API: create an API key in your settings and generate sound effects from your own apps, games and workflows.
One credit balance: the same credits are used on the web and through the API.

Try the sound effects generator

A practical first sound

Start short and concrete. For a single sound, a short prompt usually works best, such as “a heavy wooden door slams shut in a stone hallway.”
Order your events. For a scene, list events in the order you want to hear them. Wording matters, so try a few variations of the same idea.
Adjust and iterate. Set a duration when timing matters, and compare results before you use them. For seamless loops, choose a model that supports looping.

AI results vary by model, prompt and settings. Examples show creative possibilities, not a guarantee that every prompt will produce an identical result. Review your audio before publishing it.

Credits and plans

Generation uses a shared credit balance. Costs depend on the selected model and settings; the tool shows the cost before generation. The pricing page explains the available subscription plans and credit packs.
