First of all, thank you for working towards the community.
Now my question:

I´ve noticed, since i started using this plugin, that i get an high pitch noise on the streams/recordings.
I don´t know if i missed any config or something.
Do we need to disable Noise Gate in order to use this properly?

Small sample of the problem:

Just curious, if you change the sampling rate of your microphone in Windows sound control panel (under the advanced tab of the device's properties window) is there any effect?

Right now noise gate is completely bypassed because it's an audio filter added to the real microphone audio source in OBS. I wrote some code that steals the filter from the real source and moves it to the DSP source but I never tested it. I'll maybe make a new build in a few days when I get back from vacation that will enable compatibility with noise gate.

Awesome plugin, makes all the background noise disappear!

But I have some problems with it, It makes my mic sound to mumbled/low bitrate.
Is there a way to make the audio sound more clear/higher bitrate?

Hope for a fix/work around to this as soon as possible.
Would love nothing more then to use this plugin!

Hey, so I love the plugin, but I hit a problem with it last night when I tried to play some music in the background at a low volume while streaming (via Spotify): when there's no music playing, my voice is totally clear and great, but as soon as Spotify starts a track (even at like 15% volume), my voice gets incredibly distorted and it's difficult to understand me. Even when I reduce volume there's no huge improvement.

Any thoughts on how I can tweak it? I think DSP might be thinking that the music coming from Spotify is the "primary" source and it's trying to filter out my voice, coming through the microphone, since it assumes it's background noise.

Here's a video of the issue:

Works great (32-bit). I have a really really old microphone, back from 2000. Mic works well enough.
Problem I have is just normal background noise caused by my computer fans, which is very loud / notable without any filters.

Normally I would run Adobe Audition and do some DPS effects, but that puts a strain on my CPU. Running multiple programs just for the sake of a microphone filter puts a toll on my rig, and just won't work right with streaming. I recently get audio delays that I don't care to fix.

This solves all of that without the added CPU strain.
Thanks man!

Hopefully there can be more features and configuration later, but for now it works.

Edit: Would like to see a filter configuration to basically mute all noise thats below a certain dB level, and cap all volume to a certain dB level. Basically a floor and a ceiling. A slider.

For my example lets say nothing below -45dB gets through and nothing above -13dB. So we don't accidentally hurt the ears of anyone listening.

Ok I'm probably dumb, but I can't get the plugin working (first time installing one), could you help me?

EDIT: Yep, I was just dumb, fixed.

I am using 32-bit and with this plugin installed it combines my microphone and desktop audio into the same channel on OBS. I'm also using a capture card device with audio into it that is being passed through in OBS to my desktop.


New Member
i'm having issue with the plugin.

first for other who don't understand (like me)
-dowload the plugin, get in the folder and choose either the x86 or the x64 depending of your system (64 or 32 bit)
-then put the plugin in the folder PLUGIN of OBS, not the whole folder, it wont be detected.
-if the plugin is detected you will find it in OBS once you press the PLUGIN button under MICROPHONE DSP PLUGIN

ok now the problem.

since i put the plugin in the folder i can't have any sound with my mic.

i usualy use my webcam mic, a logitech c930e, or my headset mic a tiamat 7.1
but since i put the plugin, when i am in the obs windows the sound preview is actually the mic preview, when i talk i see level going up, but the mic is at zero.

and when i reccord, i get no sound at all, i though it was just a preview but no,

can you help me ?

Thank You for this fantastic resource. Before using this, I did a lot of tinkering with both OBS settings, and the system sound driver's app for mic control. This, by-far, has given me the best sound quality for my basic gear.
