What it is

Sound-effects APIs generate short non-musical audio (a door slam, rain on a roof, a sci-fi engine) from a text description, or from a video to match what happens on screen. They replace searching a stock library for the exact clip you need.

How pricing works

Billed per second or minute of audio generated, or per generation. We normalise to one minute of generated audio; because effects are short, your real cost is closer to price per generation times the number of retries.

We compare everything in one unit: USD per minute of audio.

Typical uses

  • Foley and ambience for video and games
  • Dynamic sound in apps and interactive media
  • Placeholder sound design in prototypes
  • Adding sound to AI-generated video

What to compare

  • Realism and prompt adherence
  • Maximum length
  • Looping and seamless tails
  • Sync to video

Watch out for

  • You usually need several generations to get the right take.
  • Layered effects (many sounds at once) are harder than single sounds.
  • Check licensing for commercial release.
