Do you have a manufacturer and part number for this Noise Suppressor?
Any of them will do. Pick one.Do you have a manufacturer and part number for this Noise Suppressor?
You might want to do it in a DAW instead. Audacity is not real-time, which makes the code easier, but also makes it harder to correlate settings to sounds. If you use a DAW to play back the recording, effectively live, through the chain that you're building, then the settings take effect immediately, while it's playing.I'm trying to build out the blocks in your diagram. I'm just testing with a short recording for now. Once I understand it, I'll see if I can do the same in OBS Studio.
I got the noise-repellent plugin built and was checking it out in Audacity. So that's one block.
"Inside the compressor" is literally *inside* the compressor. Every compressor has that. If you want to *build* a compressor, or any other dynamic processor, then you need one explicitly (see the app notes for analog circuitry, just below my diagrams in the same post), but if you just grab one that already exists, it's already there.In your diagram, it says "Inside the compressor" there is a block "Detector with Settings". I'm not sure what that means. Which detector is that?
"Noise" is simply an *unwanted* signal. "Unwanted" must be defined, and there's no basis in physics for what that definition should be. That's a big part of what makes it so hard to remove; physics can't help you with it.Still quite baffled how this is only going to work on human voices though.
The main input works like a normal plugin, and then you do this for the side-chain:I'm a bit perplexed how the sidechannel and main channel plug into the compressor.
Back to the (surprisingly hard) problem of defining what "noise" is, the noise being removed often has a significant amount of the wanted signal too. It's not supposed to, but nothing is perfect. For the ones that I tried, it was easily enough to still be intelligible. Otherwise yes, that *would* be a viable option.There are VST denoiser plugins that can analyze the noise (in your case, the nature sounds) and remove these sounds but let vocals through, but some also have a switch to let you only hear the noise being removed. You would use this switch all the time so the voices would be removed. Look for Blue Labs Denoiser.
