The results of our ongoing project researching a tighter coupling between computer and performer are presented: the audio-input radio drum is a simplification of the original apparatus that provides superior latency and resolution.The demodulation scheme used to extract the amplitude envelope from modulated waves is discussed.Techniques to analyze gesture data are outlined, including the estimation of parameters and detection of events.In the case of the latter, a statistical basis for making decisions in the presence of noise is presented.The algorithm used to detect when the surface of the audio-input radio drum has been hit is outlined.
