Abstract:

One advantage of modern smart phones is their ability to run complex applications such as instrument simulators.
Most available percussion applications use a trigger-type implementation to detect when a user has made a gesture
corresponding to a drum hit, which limits the expressiveness of the instrument. This paper presents an alternative method for detecting drum gestures and producing a latency-reduced output sound. Multiple features related to the shape of the percussive stroke are also extracted. These features are used in a variety of physically-inspired and novel sound mappings. The combination of these components provides an expressive percussion experience for the user.
