01 Find

Search for exactly
what you hear in your head.

In the app you can also search with AI or your voice — just describe the sound

Click to hear.
Select. Drag. Done.

Drag-and-drop depends on the target editing app

The signature move

Mid-edit?
Double-tap S.

Whatever editor you’re in, wherever the playhead is — need a sound? Tap S twice and search pops up right by your cursor. Drag it onto the timeline and the window tucks itself away, as if you never left the edit.

Always on call

Any app, any moment — double-tap S and it opens by your cursor

Drag and go

Drop a sound on the timeline and the window closes itself

Pin to keep

Pin it to keep several windows open side by side

Your shortcut

Fully customizable: single key, combo, double or triple tap

SSTry it now: tap S twice anywhere on this page, then drag a sound onto track A2 above

On macOS, cross-app use needs Accessibility permission; drag-and-drop depends on the target app.

02 Make

Not in your library?

Create SFX:
drag, and the rain gets heavier.

7 categories, 32 presets, 135 built-in sources. Rain, wind, footsteps, vehicles, doors and transitions — each with controls designed for the scene. Record it and use it.

Gesture control BETA: in the app you can also perform with hand gestures via your camera — processed only on your computer.

Generate with AI:
describe it, and it’s there.

Sound effects, music and voice. Refine from a reference sound; clone a voice once and reuse it. Jobs run in the background while you keep working.

Voice cloning, reusable

Clone a voice once from a recording you have rights to, save it to My Voices, and pick it whenever you need it.

AI features use cloud credits and results depend on the model; parameters like length are targets, not guarantees

03 Use

Pick it. Use it.
Keep editing.

Find, audition, drag — back on your timeline in three moves.

Drag or copy

Drag a sound straight into your editor, or copy it with ⌘C / Ctrl+C.

Auto-compatible

For codecs like ADPCM that editors dislike, a PCM WAV copy is prepared automatically. Your original stays as is.

Pop-out windows

Pop results into slim windows pinned beside your editor — each one searches on its own.

Project log

Every sound you use is logged to the project. Export them all, neatly, when you deliver.

And plenty more inside.

Batch name translation

FAQ

How do I join the beta?
Follow the 大羽玩AI WeChat account, then add Dayu on WeChat with the note “音效”. Once accepted you’ll be invited to the beta group, where you get the download link and bonus credits. Non-AI features are free forever for beta members.
Does it cost anything?
Library management, search and audition, clip drag-out, Create SFX and Create Music are free forever for public beta members. Cloud features — AI generation, stem separation, voice cloning, AI tagging and translation — use credits, and the cost is always shown before you submit.
Does it come with a sound library?
The app ships with the sources that power Create SFX and Create Music, so you can start right away. Dayu’s curated pack of 30,000 sound effects is available separately and searchable once imported.
Will my files be uploaded?
No — your library is indexed locally and stays on your drive. Only when you use cloud features such as AI generation, AI or voice search, or stem separation is the content needed for that task transferred.
Which editing apps can I drag into?
Any editor that accepts file drag-and-drop or paste; the result depends on the target app. For unusual codecs a compatible copy is prepared automatically.
Which systems and languages?
macOS 12+ (separate builds for Apple silicon and Intel) and Windows 10 / 11 64-bit. The app interface and AI descriptions are currently in Chinese. See the guide for installation notes.
