Vocal Lab AU 1.1.1

Vocal Lab AU helps you train to sing on key. It listens while you sing and displays the pitch of your voice on a graph, in real time. All you have to do is watch the graph while you sing and try to stay near the lines. With a little practice you can greatly improve your intonation.

Vocal Lab AU can identify problem areas in your singing, and can also help improve your intonation on various instruments - Violin, Brass, Woodwinds, and more.

Requires an application that supports "Cocoa" Audio Units plug-ins such as GarageBand 1.1 or later, Logic Express 7.1 or later, and Logic Pro 7.1 or later.
