Sing-Harmonies-2

Can an App Make You a Star?

Is it possible to offer true, rich sound on a mobile app for learning and rehearsing vocal parts? To practice new songs in integrated harmony without a choir?

Firefly maximized hardware resources and balanced file compression for high-quality playback with 5 different voices (4 voices + backing track) in sync and with individual volume control. Sing Harmonies may not make you a star, but with enough practice, no judge will say you’re off-key.
