Hi, this is Philipp from Xound. Thanks for giving our app a try, and I’m truly sorry it didn’t meet your expectations. Just to clarify, Xound wasn’t designed specifically for music processing or restoring complex choir recordings — our main focus is spoken-word audio, like interviews or podcasts. I understand your use case is very personal, and I wish we could’ve helped more. If you ever need support for voice-focused audio, we’d be happy to assist.
