# Getting audio duration with Mediabunny
|
|
|
|
Mediabunny can extract the duration of an audio file. It works in browser, Node.js, and Bun environments.
|
|
|
|
## Getting audio duration
|
|
|
|
```tsx
|
|
import { Input, ALL_FORMATS, UrlSource } from "mediabunny";
|
|
|
|
export const getAudioDuration = async (src: string) => {
|
|
const input = new Input({
|
|
formats: ALL_FORMATS,
|
|
source: new UrlSource(src, {
|
|
getRetryDelay: () => null,
|
|
}),
|
|
});
|
|
|
|
const durationInSeconds = await input.computeDuration();
|
|
return durationInSeconds;
|
|
};
|
|
```
|
|
|
|
## Usage
|
|
|
|
```tsx
|
|
const duration = await getAudioDuration("https://remotion.media/audio.mp3");
|
|
console.log(duration); // e.g. 180.5 (seconds)
|
|
```
|
|
|
|
## Using with local files
|
|
|
|
For local files, use `FileSource` instead of `UrlSource`:
|
|
|
|
```tsx
|
|
import { Input, ALL_FORMATS, FileSource } from "mediabunny";
|
|
|
|
const input = new Input({
|
|
formats: ALL_FORMATS,
|
|
source: new FileSource(file), // File object from input or drag-drop
|
|
});
|
|
|
|
const durationInSeconds = await input.computeDuration();
|
|
```
|
|
|
|
## Using with staticFile in Remotion
|
|
|
|
```tsx
|
|
import { staticFile } from "remotion";
|
|
|
|
const duration = await getAudioDuration(staticFile("audio.mp3"));
|
|
```
