_This question originally came up in our Slack community and the thread has been consolidated here for long-term reference._

Egress stores audio in `.ogg` format, but OGG is not stable across all browsers, especially Safari. Is OGG recommended for production, or should I use MP3 instead?

There’s no universal recommendation - the output format you choose should be driven by who’s consuming the files.

You have options to use:

- **AAC inside MP4** (file or HLS)
- **MP3**

Choose based on your playback requirements and browser support needs.
