AI Fixed this Super Noisy Audio!
Using footage from the upcoming 4K release of Frazetta Painting With Fire, I took some old audio from an 1985 interview that had a lot of noise and hiss and ran it through two different AI audio enhancers to achieve the following, and the results are nothing short of amazing.
The first pass I did using Audo Studio that removed all of the background noise, but it still sounded a bit hollow, so I ran the adjusted audio through Adobe Podcast (formerly Project Shasta) which added a tremendous amount of warmth to Frank's voice to make it sound as if it had been recorded in a professional recording studio.
Just in case you'd like to experiment with audio on your own, here are the two sites I used:
