Apparently this is the first audition for a lot of people on this website. I'm flattered that so many people who are new to this chose to try out for me :) Performance-wise, you're the only person who's done an openly weeping Napstablook take rather than sticking only to quieter and more reserved. Kudos for doing something new. As for rerecording to be clearer, yeah, noise removal will do wonders for you. If you think you can do better performance-wise (i.e. be more in the moment, have the lines feel real rather than something you're reading off a page - this is just general advice and not me necessarily saying you're bad), by all means do so. You only get three chances to audition for the same role on a casting call, and I'd hate for you to use two for simple noise removal :) Thanks for auditioning!

Voice removal is a thing you do not want to do in a voice acting website. Noise removal is easy if you're using Audacity - there's a plugin for it. http://www.podfeet.com/blog/recording/how-to-remove-noise-with-audacity/
