I went to the page top discover a close miked female vocal with a bit of processing. Nothing remotely special and certainly it has no specialness in it's timbre or clarity. In essence, some autotuning and dynamics. Oddly, the video has no comments, seems to be collecting likes and was posted today, and the coincidence being this is your first post - so would perchance, you be posting about your own video?
Seriously - I hate the result. Processed, thin and breathy. Fair enough, it's not my choice of genre - but I have issues with the description of crystal clear audio when it's fiddled with and compressed. If you want crystal clear audio on a vocal, then go back in time to Karen Carpenter, Bette Midler, Celine Dion - they were crystal clear compared to this.
Sorry - but I don't think this is genuine. How do you get this kind of vocal clarity? Squash the hell out of it with dynamics processing is the wrong answer.
