Introducing Sonilo Sound Effects 1.0

A step toward a Sound World Model for video

Sonilo Sound Effects 1.0 reads a video’s timing, pacing, and emotion, then places music and sound effects on the action as one finished, licensed track. Generate from video or text, available now via the Sonilo API.

Published July 25, 2026 by Sonilo Team.

A generated sound has one pass-fail test: you believe it, or you don’t. A sports car either sounds like that engine, at that speed, from that distance, or the whole shot feels fake.

We built Sonilo Sound Effects 1.0 around that standard. It is another step toward a Sound World Model for video: a model that understands what is happening on screen, when it happens, how fast it moves, how far away it is, and what the moment should feel like.

Upload a video and Sonilo returns original music and sound effects, placed on the action, as one finished track. Or start with a text prompt and generate original sound effects directly. Every track is licensed.

The video decides the placement, not your timeline

The decision we want to talk about is the one you can’t see in the demo. We could have shipped loose sound clips and left the placement to you. That version demos fine. It also leaves you searching libraries, cutting clips, and lining up sound by hand, which is the exact work we set out to remove.

So the model reads the footage before it generates anything: the timing, pacing, action, and emotion of every scene. It has to know when the engine revs before it makes the rev.

Music and effects, one finished track

Music works the same way. It follows the story instead of looping under it, and it comes from the same upload as the effects. One finished track, balanced, not a stack of clips left for you to mix.

Leading the benchmarks

Sonilo Sound Effects 1.0 leads across video-to-sound-effects and text-to-sound-effects benchmarks, including action synchronization, scene-to-sound understanding, prompt matching, and perceived audio quality.

Sonilo Music 1.1 outperforms Suno v5.5 on 8 of 13 MusicCaps benchmarks for instrumental music generation.

A Sound World Model

The longer arc is a Sound World Model: one model that reads what happens on screen and generates soundtracks for it end to end. Music carries emotion. Sound Effects creates presence.

Tell us if you believe the engine.

Both are available now via API access, with free trials to get started.
