Overtone Analyzer is a software application for recording and exploring sound, especially the sound of the voice and of musical instruments. It helps to visualize, measure and understand three main aspects of your sound:

Pitch

• What pitch am I singing or playing?
• Is my instrument in tune?
• How is my vibrato?

Timbre

• How strong are the different harmonics / overtones?
• How is my resonance?
• What are the relations between the physiology of the voice, the physics of sound, and the theory of music?

Change

• How does my sound change over time?
• How does my voice develop, and what progress have I made?
• How do different recordings look and sound in comparison?
