REAL-TIME DESIGN SYSTEM FOR WIND INSTRUMENT

摘要

PURPOSE:To provide a system in which not only the interval but also the timbre and ease of playing are simulated and predicted under a realistic playing condition. CONSTITUTION:The system consists of a sensor 1 which is installed in the mouth side part of a straight pipe connected to a mouthpiece to convert acoustic waves transmitted from the mouthpiece side to electric signals, an actuator 4 which is installed at the entrance part of the pipe to reconvert the electric signals that are converted by the sensor 1 to acoustic waves and to provide an acoustic output to the entrance part of the pipe, an electronic delaying means 2 which physically simulates the wind instrument main body by delaying the electric signals outputted from the sensor 1 for a prescribed period and a computing means 3 which processes the delayed electric signals outputted by the means 2 so that the performance of the body is confirmed in real-time while a user actually plays the instrument.
