Visualizing sound flow on orchestra performance

摘要

The sound flow is important to recognize the self-motion and the external environment. We introduce the sound pattern which caused by moving sound sources relatively for the receiver as the sound flow. We define the calculation method of the sound flow by extending the calculation method of the optical flow. We pay attention to the sound pitch and the sound volume of each frequency. It is found that the effectiveness by visualizing the simulated sound flow while "Kanon" composed by Pachelbel is played by the string quartet in the virtual multipurpose hole at Yamaguchi university.
