+## Custom encoding
+
+By default, the recording is encoded into `audio/wav` format. In order to reduce the size and keep the inter-browser format compatibility, you can use an MP3 encoder that is based on [`lamejs` implementation](https://github.com/gideonstele/lamejs). Follow these steps to achieve the MP3 encoding capability.
+
+1. The library `@breezystack/lamejs` has to be installed as this is a peer dependency to `stream-chat-react`.
+
+```shell
+npm install @breezystack/lamejs
+```
+
+```shell
+yarn add @breezystack/lamejs
+```
+
+2. The MP3 encoder has to be imported separately as a plugin:
+
+```tsx
+import { MessageInput } from 'stream-chat-react';
+import { encodeToMp3 } from 'stream-chat-react/mp3-encoder';
+
+<MessageInput focus audioRecordingConfig={{ transcoderConfig: { encoder: encodeToMp3 } }} />;

+## Audio recordings transcoding
+
+Until now, the audio recordings were transcoded to `audio/mp3` format for inter-browser compatibility and size reduction. However, as of the v12, the MIME type `audio/wav` will be the default. The MP3 encoder use is opt-in from now on.
