## What it is
An OBS Studio plugin that adds an 'Application Audio Output Capture' source, letting users capture audio from a single application on Windows instead of the whole system. It uses the Windows process loopback API and requires Windows 10 2004+ or Windows 11.

## Use cases
- capture game audio separately from discord in OBS
- record audio from one application only
- stream a single app's sound without a virtual audio cable
- separate app audio tracks in OBS recordings
- avoid latency from software audio mixers

## When to choose
- you use OBS on Windows 10 2004+ or Windows 11 and need per-application audio capture
- you want to avoid virtual audio cable setups or hardware mixers

## When to avoid
- you are on macOS or Linux
- your Windows 10 install is older than 2004 or not fully updated
- you need production-grade stability, as the plugin is in beta
