Hey Matt, hope everything is good with you.
I've also heard metion of De-Verb, and that was about the extent of my exposure to it until your post here pointed me to their website. Looks like their plugins target what have previously been considered sort of 'holy grail' audio applications. Their De-Filter plugin is also interestesting and may be even more widely applicable for our applications generally (not just the over-verby ones), assuming it actually works well.
From the website descriptions it sounds like these plugins are system resource heavy, which makes sense considering the complex computational tasks involved.
The trial versions don't seem overly restricitve. I'll have to check them out when I get a chance.
I have numerous problematic recordings I've kept stashed away specifically with the intent of revisiting them once the signal processing state of the art progressed and trickled down far enough to me to properly salvage them. At the time I did so knowing that it would only be a matter of time, advancing processing power, and creative tool development before these kind of signal processing tools became available, good enough, and inexpensive enough that revisiting them eventually makes sense.
High quality spectral repair is another one of those things which showed up first. These seem to be next and are in that same category to my way of thinking.
