I'm trying to find a way to batch clean up a large set of recordings by creating two tracks, one with all the random snaps, clacks, thumps, vertical / percussive sounds, and one with tonal / horizontal non-percussive sounds. This means that the algorithm doesn't have to be perfect because I'll manually decide where to mute the vertical track. It will be much faster than doing manual selection in RX.
RX deconstruct doesn't work because it groups all noise together including horizontal stuff. I figured the transient feature would do the vertical stuff but it really doesn't. It just gets a tiny bit of click out of a larger sound, it's somewhat useless.
I tried RX music rebalance to see if I could get the algorithm to group all the percussive sounds together.... nope. I tried a bunch of different RX tools to see if any of them would consistently target vertical sounds. The only one that does pretty well is attenuate (it checks what part of the spectrum has sudden peaks and removes those peaks) but that is a completely manual tool.
I'm pretty sure there are some pitch shifting algorithms that need to take this into account to preserve percussiveness. Also bouncing off of this thread: viewtopic.php?p=8510509#p8510509
Separate spectrally vertical vs horizontal sounds (kinda like RX deconstruct)?

Maybe you could try SpectraLayers from Steinberg which has an "Unmix Components" module which separates the source audio into 3 layers noise, transient and tonal. Playing with FFT sizes has an impact on the separation, so maybe there is a perfect FFT size for your material.

IrcamLabs TS2 is worth a look https://www.ircamlab.com/products/p1680-TS2/ on special for $40 which is incredible value

My first thought is Eventide's Physion ( https://www.eventideaudio.com/plug-ins/physion-mk-ii/ ) or SplitEQ ( https://www.eventideaudio.com/plug-ins/spliteq/ ) ... I don't remember them being that crazy price though, must've grabbed them in an early-bird deal

SpectraLayers is what you're looking for. It can unmix components (tonals, noise, transients) with more accuracy than RX, it can unmix drums into kick/snare/hi-hats/cymbals, it can unmix by spectral levels, etc etc.

It looks like Ircam and Spectralayers works pretty much like RX with the exception of having more control which is an improvement, but they are still putting transient-type sounds and continuous / broadband noise together. Physion fails in a similar manner.
TIMT did you mean voice of snow? Found the link: http://static.kvraudio.com/files/3219/v ... w1_0_1.zip unfortunately it doesn't separate very well the entire intrusive sound

Is there an in-daw spectral editor where you draw squares where you want to mute sound? If I could do that then I could arbitrarily mute spectra where the intrusive sounds are happening, that way I don't need to rely on broadband noise/percussive separation, and just rely on tone/noise separation... hmm that would create holes in the spectra which would be audible...
Edit: I did just discover that using a good denoiser (RX?) and denoising away the desired instrument sound (multiple times, learn different sections until the instrument is removed), you are left with the undesired sound which can then be inverted... or perhaps one pass just removing the "signal" (which removes the undesired sound) works pretty well. Only problem is the manual learning.
Edit: Oh, REAPER has it built in now apparently. https://www.youtube.com/watch?v=vSBO_VC9q3E

Do you have an example file - TS2 is pretty good using Remix - with spectral clipping sometimes
