The project I've been working on for the last eight months has now released our first public release. Humtap is a mobile app for collaborative music making. Users collaborate by each recording hums and taps into their mobile phones. These audio recordings are transcribed and become musical avatars. A user can then create a piece of music (currently of the electronica genre) by combining their hum or tap with another user's tap or hum, or with their own tap or hum. Finally, users can also create a new piece of music by combining two other user's hum and tap. The app combines the transcriptions in a musical way and selects the electronic instrumentation.
