    I tried the Audacity noise-removal plugin recently and it's complete crap. I fed a high-quality audio stream from a Rode mic into a few different options to see which could remove the noise of my server rack. iMovie made the voice sound like a robot and Audacity barely did anything. The only thing that worked was DeepFilterNet and it's free, open-source and cargo installable.

    There's no reason to lock yourself into an intel-only solution. Just use DeepFilterNet. The results of this on my noisy server room were insanely good. Almost no voice dropout with 100% fan noise removal.

    EDIT: Even more interesting, it looks like OpenVino is just DeepFilterNet glued to Whisper.cpp and tied to Intel hardware.

    This only works with Intel GPUs, and CPUs and NPUs. No Nvidia support for instance.

    Is there a tool that can remove very noisy audio recording of a song using actual song as a reference?

    I found a very old audio cassette from my childhood with me and some other kids talking while a song is playing in background. I tried subtracting the song using Audacity but for that to work reference song and recording must align "perfectly" which is very very hard. Not just the timing (which i found can be a problem with cassettes) loudness/frequency distribution must also align perfectly.

    Found Smartsubtract https://oxfordwaveresearch.com/products/smartsubtract/ which seems to do exactly the same but it's not available for download.

    Is there any (AI even?) tool that might do that? I tried an online AI tool which claimed it can extract voices but it returned back silence. I want to try OpenVino but not sure it will be useful with faint spoken words in a noisy environment with a song.

    I'm a big fan of RTX Voice, but it seems like the kind of feature you can only use in real-time as virtual audio and not as postprocessing. Anyone if Nvidia makes this possible?

    Wonder if these are open models like RNNoise now is.
