Sonilo

What is Sonilo

Sonilo is an AI-powered tool that generates original music and sound effects from finished video. It analyzes the timing, pacing, and emotional arc of a video to compose music that matches the video length and places sound effects on exact action frames, returning a single finished audio track. Sonilo also offers text-to-music, text-to-sound-effects, dubbing, and audio ducking. All tracks are licensed for commercial use on eligible plans. It runs on the web and via API, with a free plan to start.

How to use Sonilo

1. Start with video or text: Upload a video (MP4 or MOV) and Sonilo analyzes the cut without needing a prompt. Alternatively, describe the desired sound and Sonilo generates from text alone.
2. Scored in sections: Music and sound effects are generated as real tracks, matched to the video's timeline or to a specified length.
3. Export your way: Download the finished video with all tracks mixed in, or export the music and sound effects as separate files.
