Pitch Coach is a mobile app that aims to help people learn to sing through an interactive and game-like interface using pitch detection and other voice analysis technologies. It offers varied training modes and promises to make singing lessons more accessible and affordable by bringing them to mobile devices. The creators demonstrated the app and discussed how they use techniques like discrete cosine transform and harmonic product spectrum for pitch detection as well as how promises in JavaScript help manage asynchronous events in the app. They also outlined planned future enhancements including a song mode and pitch-controlled games before taking questions.
