An OBS plugin that allows capture of independant application audio streams on Windows, in a similar fashion to OBS's game capture and Discord's application stre
An OBS plugin similar to OBS's win-capture/game-capture that allows for audio capture from a specific application, rather than the system's audio as a whole. This eliminates the need for third-party software or hardware audio mixing tools that introduce complexity, and in the case of software tools, introduce mandatory latency.
Internally it uses ActivateAudioInterfaceAsync with AUDIOCLIENT_PROCESS_LOOPBACK_PARAMS. This initialization structure is only officially available on Windows 11, however it appears to work additionally on relatively recent versions of Windows 10.
This plugin is in a BETA state, expect issues - https://discord.gg/4D5Yk5gFnM for support and updates.
An updated version of Windows 10 2004 (released 2020-05-27) or later is required.

obs-studio/, not obs-studio/obs-plugins/) when asked (or extract the zip to the portable OBS root directory)Application Audio Output Capture source not showing up after install: this means that either your OBS is out-of-date (check that it is at least 27.1.x) or you have installed the plugin to the wrong location. To re-install, first uninstall via "Add or remove programs" in the Windows settings, and then run the installer again. Make sure to select the top-level obs-studio/ folder in (probably) C:/Program Files/.
Application Audio Output Capture source not picking up any audio: this happens when your Windows is too old and does not have support for the API. Note that even if you have a more recent major version such as 20H2 you will still need the latest updates for the plugin to work. If you are on a very old version you might need more than one update for this to work, and the second update might not show up for a few days after the first update.
