Indie developer Sejin Kim today introduces Funi Player 1.01 for iOS, his music-editing app that gives users an innovative way to listen to and enhance the songs in their music collection. Users may isolate vocals or instruments, adjust the speed of the tracks, or listen to songs backwards in this powerful Music editing app. Taking music listening to a new level, Funi Player users can create custom recordings of edited music creations for karaoke, artistic creation, musical practice or fun.
