I have plenty of projects where I am asked to clean up and master a track combined of different snippets (for example, an interview or an ad footage taken in different places with different acoustic and noise floor conditions, and then tied up).
In such a cases you can’t just pass your track through Noise Reduction automatic module. These cases require much more neat and individual approach. You have to teach your De-Noiser (De-Reverb module as well) every time you see a new chunk. Then these fragments should be levelled and EQ-ed to make a feeling of consistency.
That’s why I offer a bespoke audio editing/ restoration/ mastering and it still is in-demand. Reach out, I am comfortable to work with ツ
UPD: here’s another reason why you probably want to deal with professional engineer.
