Free app turns your drawings into music

There are plenty of music making apps out there but what about an app that takes inspiration from your own drawings? No matter what your ability, this new app from Ed Burton can turn any sketch into a new tune.

Using OpenCV (opens in new tab) and OpenFrameworks (opens in new tab), Tunetrace (opens in new tab) transforms photographs of drawings into music. OpenFrameworks first finds the edges in your photographs, then reduce them to polylines and uses them as paths for different tones.

Created for iPhone and iPad, Tunetrace is the latest music-making app to be developed by QApps (opens in new tab), which aims to turn research and expertise into useful and exciting smartphone technology.
