Hi..
I`m Peter, experienced audio-freelancer.
I worked with similar edits to bring more quality to source audio /denoising, EQ, dereverb, amplify etc..
For it I use in my audio-studio professional postproduction tools from Izotope, Audition and more.
..some demo-samples from past works are in my profile portfolio..
Pls send me short sample of one from your recordings, I need to check problems and get "what can be done" - I`ll prepare from it for you sample "before-after editing"
then, if you `ll like my edits, we can chat to clear all your project details and go..
