Sorry, I thought that most lost interest in this thread.
I did play around with the concept of of mixing a gated track out of polarity with your source track and summing that with the original. When listening to the process it's very interesting. It sounds similar to someone using a volume pedal; smacking it down whenever a transient hits. Almost sounds like playing the track in reverse, except it's forward.
If it's cool with you I'll post samples of the processed track, the mix of the processed track with the original (pseudo upward compression or whatever you want to call it), and the original for comparison.
My impression overall is that it gives the track a more saturated sound without affecting the transients.
BTW nicely recorded!
Best,
Tom
