Features

Sonilo Video-to-SFX generates sound effects for an input video. Upload a video, optionally describe the overall sound direction, choose the output audio format, and generate a synchronized sound-effect track for the source video.

Why Choose This?

• Video-to-sound-effect generation
  Generate sound effects based on the content, motion, and timing of an input video.

• Optional prompt guidance
  Add an overall prompt to guide the sound style, environment, intensity, or realism.

• Automatic video-aware timing
  The generated sound effect track follows the source video duration.

• Multiple audio formats
  Export audio as wav, mp3, aac, or flac.

• Standard audio output
  Generated audio is returned as a URL in the standard WaveSpeed prediction response.
