Fixing Audio Recorded from a DSLR Camera

John_Sac9  wrote There is deverberate from Acon Digital https://acondigital.com/products/deverberate/ which is really impressive for removing reverb from the track, but it's still a rescue, not a fix.

I'm afraid that I find their claims to be rather exaggerated. Especially this one:

"The Early Reflections Filter uses sophisticated statistical methods to estimate the so called impulse response of the early reflections. The impulse response is then utilized to calculate an inverse filter that cancels out the effect of the early reflections."

The whole point of an impulse response is that it's an accurate representation of a room's characteristics, and all rooms have a unique impulse response, dependent entirely on the relative positions of the source and receiver. You simply cannot create a 'statistical' version of one and expect to have even a shred of accuracy about it! There are lies, damned lies, and then statistics...

Original answer stands - you can't use a NR program (and not a particularly good one at that - iZotope's RX will do a better job) to get rid of a room response, which is what the OP was asking about. This is not about cleaning noise away from dialog - which Audition's Adaptive NR will do just as well - but something that is essentially un-fixable in any sort of usable way.

We might know a thing or two, but unfortunately one of those things is that it's pretty much impossible to fix camera audio recorded at a distance, with unremoveable room tone...
