Singscope

Singscope is a real-time pitch analysis tool that visualizes your singing pitch on a live scope. It converts your voice into a pitch curve aligned to the music scale and lets you see features like vibrato as you sing. You can pan and zoom the pitch graph, play back recordings, and review recent takes for improvement.

This Chrome extension includes an optional Sheet Music Support Pack (in-app purchase) to add sheet music warm-ups, import a subset of MusicXML lead sheets, play notes along with your voice, and control tempo and transposition. It also highlights notes on the pitch graph to help you practice more effectively.
