I was thinking out loud one day and I realized that I don't have much of a singing voice, but I want to be able to sound good if I were to sing out loud. Hence the problem. Here is what I perceive as the solution to the problem. I consider it putting two and two together. There are pitch correcting pedals, devices and software. Also there are music playing apps where it can take in MIDI music files and can correspondingly highlight the lyrics as the musical notes are played. Maybe the youtube videos of karaoke examples did the matching manually. So how about an app that lets me read the lyrics in the music in time to the music? And via airplay play the sound of my voice, pitch corrected, to the notes in the music via the loudspeaker. Anyone know of an app that can do this?
