Spring 2013, TuneTrain(App Store), 200,000+ download, a music education iOS Application, encourage children to create music by drawing. Position: Programmer for Voice Detection, Midi-to-Notation Algorithm, Sequencer (team of 7)

We are creating a stimulating experience that is easy to use, highly educational, and fun to play with. Kids are able to utilize gestural touchscreen interactions to generate melodic phrases. At the same time, they will learn about how music is put together without any need of prior musical instruction. With the aid of features like automatic audio accompaniment and pitch graph to sheet music conversion, children will have the power to create music that they are proud of and want to share with others.

Notation Generation Algorithm

Musical notation conversion is a system that helps to emphasize the musical foundations of the experience.  This feature processes the user’s drawn melody line into equivalent musical notation in real time . Transcribing a song to musical notation is a difficult algorithmic task that requires identifying many unique cases, such as when to beam notes together, or when to tie notes together . Implementing such a system requires an appreciable amount of time and can be intimidating, and I managed to finish the algorithm design and implementation within 3 weeks.
