This is of potential interest for anyone wondering about using the recently added OpenVino AI noise suppression plug-in in Audacity, and for anyone wanting to improve noise reduction in natural soundscape (or indeed other) recordings, without paying big money.
I've now uploaded a revised and dramatically improved version of my Nature-Symphony 70 (Flies as musicians 5: pentatonic and major, with pedal tone), which I'm also calling Rannoch Moor Moods, 3 — https://freesound.org/people/Philip_Goddard/sounds/759413/ .
This was made possible by my breakthroughs in getting considerably better noise-reduction without noticeable artifacts. In my notes for the new version I explain about that, and give details of how I achieved such a big noise-reduction with minimal loss or degradation of the 'wanted' sounds. This breakthrough is amazing considering that that OpenVino module is modelled for extracting voices, so one would hardly expect it to work well for natural soundscapes.
It certainly proved tricky, though, to get it just right — you'll note that I also used Audacity's spectral subtraction noise reduction, so I'm being very pragmatic about this and no longer looking for a single 'silver bullet' to do the job.
