# Using audio in Remotion
## Prerequisites
First, the @remotion/media package needs to be installed.
If it is not installed, use the following command:
```bash
npx remotion add @remotion/media # If project uses npm
bunx remotion add @remotion/media # If project uses bun
yarn remotion add @remotion/media # If project uses yarn
pnpm exec remotion add @remotion/media # If project uses pnpm
```
## Importing Audio
Use `
` from `@remotion/media` to add audio to your composition.
```tsx
import { Audio } from "@remotion/media";
import { staticFile } from "remotion";
export const MyComposition = () => {
return ` components.
## Trimming
Use `trimBefore` and `trimAfter` to remove portions of the audio. Values are in frames.
```tsx
const { fps } = useVideoConfig();
return (
interpolate(f, [0, 1 * fps], [0, 1], { extrapolateRight: "clamp" })
}
/>
);
```
The value of `f` starts at 0 when the audio begins to play, not the composition frame.
## Muting
Use `muted` to silence the audio. It can be set dynamically:
```tsx
const frame = useCurrentFrame();
const { fps } = useVideoConfig();
return (
= 2 * fps && frame
);
```
## Speed
Use `playbackRate` to change the playback speed:
```tsx
interpolate(f, [0, 300], [1, 0])} // Fade out over multiple loops
/>
```
## Pitch
Use `toneFrequency` to adjust the pitch without affecting speed. Values range from 0.01 to 2:
```tsx
