add-sfx（添加音效）

Prerequisites

Sound effects must first be added to the remotion.media repository. The source of truth is generate.ts in that repo. A sound effect must exist there before it can be added to @remotion/sfx.

Sound effects must be:

• WAV format
• CC0 (Creative Commons 0) licensed
• Normalized to peak at -3dB

Steps

1. Add to remotion.media repo (must be done first)

In the remotion-dev/remotion.media repo:

1. Add the WAV file to the root of the repo
2. Add an entry to the soundEffects array in generate.ts: {fileName: "my-sound.wav", attribution: "Description by Author -- https://source-url -- License: Creative Commons 0",},
3. Run bun generate.ts to copy it to files/ and regenerate variants.json
4. Deploy

2. Add the export to packages/sfx/src/index.ts

Use camelCase for the variable name. Avoid JavaScript reserved words (e.g. use uiSwitch not switch).

export const mySound = 'https://remotion.media/my-sound.wav';

3. Create a doc page at packages/docs/docs/sfx/<name>.mdx

Follow the pattern of existing pages (e.g. whip.mdx). Include:

• Frontmatter with image, title (camelCase export name), crumb: '@remotion/sfx'
• <AvailableFrom> tag with the next release version
• <PlayButton> import and usage
• Description
• Example code using @remotion/media's <Audio> component
• Value section with the URL in a fenced code block
• Duration section (fetch the file and use afinfo on macOS to get duration/format)
• Attribution section with source link and license
• See also section linking to related sound effects

4. Register in sidebar and table of contents

• packages/docs/sidebars.ts — add 'sfx/<name>' to the @remotion/sfx category items
• packages/docs/docs/sfx/table-of-contents.tsx — add a <TOCItem> with a <PlayButton size={32}>

5. Update the skills rule file

Add the new URL to the list in packages/skills/skills/remotion/rules/sfx.md.

6. Build

cd packages/sfx && bun run make

Naming conventions

Version

Use the current version from packages/core/src/version.ts. For docs <AvailableFrom>, increment the patch version by 1.
