For those interested in such things, Oeksound have a sale on Soothe2 right now and they rarely do sales.
It’s advertised as a deharsher / or clarity maker depending on your use case, and it can be very helpful with complicated audio sources where a de-esser or a dynamic EQ can’t quite manage to do the job.
It’s hyper-specific and pretty expensive for what it is but as often I found out those kind of plugins are the ones I end up using the most.
Also 10/10 for the clarity of the interface and visual feedback.
