[音像實驗室] 1/30 電流急急棒




在這個實驗中,一開始拖拉出來的紅綠線決定了聲音的音高(越長聲音越高)­,而接下來的控制點距離紅綠線上的距離,決定了聲音的振幅(越遠音量越大),最後控制點­映射到紅綠線上的交點,這交點距離紅綠線端點的比例,決定了聲音持續的長度(一秒鐘要響多久)。


In this experiment, the red/green line pulled out at the beginning decides the pitch of the sound (the longer the line, the higher the pitch). The following distance between the control point and the red/green line decides the amplitude of the sound (the farther the distance, the louder the sound). Finally, the prportion between the distance between the crossover point reflected by the control point to the red/green line and the ends of the red/green line decides the length of the sound.
