    • A performance apparatus 11 extends in its longitudinal direction to be held by a player with his or her hand, and is provided with an acceleration sensor 23 for detecting an acceleration sensor value and an angular rate sensor 22 for detecting an angular rate of rotation of the apparatus 11 about its longitudinal axis. CPU 21 detects a sound-generation timing based on the acceleration sensor value. Using the angular rate, CPU 21 calculates a rotation angle of the performance apparatus 11 made about its longitudinal axis in a period from a first and a second timing, wherein the first and second timing correspond to starting and finishing of swinging motion of the performance apparatus, respectively. CPU 21 determines to increase or decrease a sound volume level, in accordance with the direction and amount of the calculated rotation angle, thereby adjusting a sound volume level of musical tone.
    • 演奏装置11在其纵向方向上延伸以由他或她的手握持,并且设置有用于检测加速度传感器值的加速度传感器23和用于检测加速度传感器值的角速度传感器22 装置11围绕其纵向轴线。 CPU21基于加速度传感器值检测声音生成定时。 使用角速度,CPU21在从第一和第二定时的周期内计算出演奏装置11的纵轴的旋转角度,其中第一和第二定时对应于演奏装置的摆动运动的开始和结束 , 分别。 CPU21根据所计算的旋转角度的方向和量来确定增加或减少音量水平,从而调节乐音的音量水平。

    • An audio generating apparatus includes: a sensor which senses a motion of a predetermined apparatus and generates a sensor signal corresponding to the sensed motion; a motion pattern recognizer which recognizes a motion pattern of the predetermined apparatus based on the sensor signal; and an audio signal generator which generates an audio signal corresponding to the motion pattern. The motion pattern recognizer includes: an analog-to-digital converter which converts the sensor signal into a digital sensor signal; and a motion pattern analyzer which analyzes the motion pattern of the predetermined apparatus based on the digital sensor signal. The audio signal generator includes: a storage medium which stores the motion pattern of the predetermined apparatus and audio signal data corresponding to the motion pattern; and a signal generator which extracts the audio signal data from the storage medium to generate the audio signal.
