Hi..
I`m Peter, an experienced, detail-oriented audio-freelancer /pls check my past works evaluations in my profile/
I work 15+yrs with relax-meditation projects (including producing custom made unique music backgrounds for it +meditation-relax custom created BrainWave tracks +mix-mastering all)
I checked your source-recordings at google-drive link - all of them need:
or
1/ cheap-quick made "denoising",
or
2/
detail oriented cleaning incl denoising, EQ, leveling, compressing and more (using professional tools for such complicated by tech-problems your source audios) =I have and use profi set of tools from Izotope, Audition, Melodyne,VocSync and more.. it "eats" lot of time by processing, but done properly can save your recordings from trash, and can convert it to professional audios for further use (sell? market?..)
..with my "tools" I can eliminate unwanted f.i. "door slam" during recording.. or another so not easy, not common things.. some examples of postproduction work made by me, and my past work evaluations you can find in my profile (to go there-pls click on my icon or portfolio link)
I`m not cheap, but I`m professional (specialized in relax-meditation)..
it is your decision "what result you want" /cheap-quick, or professional/ - let`s chat about it all, clear all and start..
