description: The @mediabunny/dts extension provides fast DTS decoders and encoders for both browser and server environments.
---
# @mediabunny/dts
Browsers have no support for the DTS audio codec in their WebCodecs implementations. This extension package provides both a decoder and encoder for use with Mediabunny, allowing you to decode and encode this codec directly in the browser. It is implemented using Mediabunny's [custom coder API](../supported-formats-and-codecs#custom-coders) and uses a fast, size-optimized WASM build of [FFmpeg](https://ffmpeg.org/)'s DTS coders under the hood.

## Installation
This library peer-depends on Mediabunny. Install both using npm:
```bash
npm install mediabunny @mediabunny/dts
```
Alternatively, directly include them using a script tag:
```html
<script src="mediabunny.js"></script>
<script src="mediabunny-dts.js"></script>
```
This will expose the global objects `Mediabunny` and `MediabunnyDts`. Use `mediabunny-dts.d.ts` to provide types for these globals. You can download the built distribution files from the [releases page](https://github.com/Vanilagy/mediabunny/releases).
## Usage
```ts
import { registerDtsDecoder, registerDtsEncoder } from '@mediabunny/dts';
registerDtsDecoder();
registerDtsEncoder();
```
That's it - Mediabunny now uses the registered DTS decoder and encoder automatically.
