win-capture-audio v2.1.0-beta

Supported Bit Versions
Source Code URL
Minimum OBS Studio Version
Supported Platforms
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 - for support and updates.
An updated version of Windows 10 2004 (released 2020-05-27) or later is required.

See the for installation instructions.

A detail, I was with windows 11 and my obs was crashing every time it closed and giving a lot of error, I formatted the computer and installed windows 10 and the problem continued, I removed this plugin from my obs and now it's working normally, before I couldn't close it without task manager, so it doesn't work for me, but the idea is good, if I improve the plugin in the future, I'll remove this note.
I have to ask this. I know this might sound dumb but how do I uninstall it if I want to update it and just know I did not download it yet since I would like to know how to uninstall it first
Thank you! This is way easier than messing with windows audio settings, installing virtual audio cables, etc.
Just add an audio source, choose which application to record, and you're good to go.
Realy nice job, congrats.
I'm having some issues in capturing audio from chrome (mult windows open) sometimes take time for the plug-in to recognize the correct window and in youtube, when the song chance I´m getting a hard daley for the new song to be cast on OBS.

Sometimes crashes when using with Audio Monitor plug-ing.

And, I think it will be a good thing to do is add virtual cables, so we can use system sounds.

Thanks a lot... noice job!!
Managed to replace Voicemeeter with this plugin and it's pretty amazing. I only have issues with it not having game detection to associate it with a source but also because my OBS now freezes when I'm closing it and has to be force closed.
Perfect. No need to mess with (great but somewhat confusing) programs like VoiceMeeter and confusing loopbacks just to control what audio you want to let your stream hear.
Works great, even on Windows 10 21H1. No more hassle with separating audio. You just grab the app to get its sound and its sound only. Should be an integral part of OBS in the first place.
Wonderful plugin and simple enough in execution. Thanks for doing the good work out there!
works exactly as described and that with win 10 "21H1"
EXTREMELY useful. I usually record gameplays with some friends on discord. So this plugin is a life changer for me. :D
