Plugin for OBS Studio to add Audio Monitor dock and filter. It allows you to put the audio of a OBS source to an audio device by adding the Audio Monitor filter on the Source in OBS Studio.


This can be useful in different use cases:
  • monitoring a source on multiple devices
  • monitoring audio without the delays of syncing to video
  • separate monitoring audio levels per source and device

The idea for this plugin is a request from FeVR

You can donate to me via PayPal, GitHub or Patreon.

Again, version 0.8.2 still crashing with Touch Portal, less, but still crashing
I'm excited about the plugin, the functions are fine
I want to love this....but sadly right now it crashes as soon as OBS opens due to the TouchPortal problem that others have posted about. Hopefully this will get updated to fix the conflict!
I loved the plugin in previous versions of OBS.
But since OBS 28 (yes, I updated the plugin :D) I have the following problem: When I move a fader in the audio mixer or audio monitor panel, I suddenly get an extremely high CPU load, the sound stutters and OBS crashes after a short time. This happens no matter how the plugin is set.
If I remove the audio monitor filter from the sound source, the problem no longer exists. Therefore, unfortunately not usable right now, I hope it will be fixed quickly!
Was very satisfied so far!
Love this extension. Gives full matrix support so each audio input can have a separate volume to each output.

Current issue: Many of the audio inputs don't display output meters, just sliders. Kind of tough to know if I am getting input without the display.
the plugin is amazing BUT, i found out after thorough search - this plugin is crashing my OBS v28 whenever we connect with touchportal, sammi, deckboard using websocket 5.

there arent any other plugins just this thats causing the issue
3 Stars because it works fine on OBS 28.03 but When i use it with Touch Portal 3.1 Build 7, OBS Crashes, i try remove other plugins and i find out that it was this one that crashes when i have Touch Portal open, if i remove the plugin, all works fine. Help please
Awesome plugin! You can choose different speakers to monitor each audio! I'm just rating it 4 starts because 0.8.1 doesn't work with OBS 27.2.4 and I can't download 0.7.1, download link please?
Big issues with audio becoming out of sync.

OBS with video capture and microphone input.

1. Set Audio monitoring to HDMI output (TV for example)
2. Full Screen Projector to the same HDMI output.
No issues with the synchronisation between the video and the audio

3. Add Audio Monitor to the microphone input to play though desktop speakers/sound card

Audio just gets more and more out of sync the longer it runs for. Around half a second in 10 mins.

Please find a solution as I love this plugin!
I LOVE this tool! it gives a total liberty to manage your sources independently, Exeldro is a genius!

I have indeed two problems, the first is each time I'm making a Win Update: The assigned sources change to strange numbers and symbols, or the source names are cut, so they don't work more until I reselect the sources one by one on each music filter.

The second problem came with the last OBS version (28): The audio start to crack as soon as I'm moving the Volume-cursor... and when I switch to another scene and come back, OBS crashes.

So I'm excited to receive an Update soon! Thank you very much, Exeldro!
