What it supports


Special features

BPM control

Specify an exact tempo in your prompt (e.g. “at 90 BPM”) and the output locks to it, so loops sync cleanly with an existing track.

Foley support

Everyday, real-world sounds like footsteps, cloth rustle, or object handling, ready to layer into film, video, and game audio.

Audio length control

Set the exact duration, from 5 seconds to 2 minutes, with the audio_length parameter.

Endpoint

Use this endpoint to generate sounds based on a text description.

Sample Output

Listen to an actual sample: Prompt: sound of bird chirping in a forest. Download Audio

Try it Yourself

Visit the Sound Generator Endpoint Explorer to try live prompt-based sound creation.
🚀 Experiment with different descriptions — from realistic sounds (like “city street at night”) to fantastical ones (“alien spacecraft landing”)!
