I should say sub-frame edits. Its where you edit parts of the audio within a frame for different effects or to fix audio issues (Sometimes its required when you're using 2-3 audio tracks).
I should ask because I wasn't quite sure what you meant here, what exactly would be integrating pro-quality sound be? Like adding sound effects to the video? And is it all provided or are you looking for someone to make AND integrate?

Good luck finding someone! I've never done sound with animation myself but I've done plenty of frame by frame sound edits because of the YouTubers I work with and teach XD

Interesting! I'm not sure what frame by frame sound edits are, but thanks for the well-wishes!
