Toshiya Tsunoda - Appearance of physical vibration: These recordings are studies of the sonic effects of physical vibration Track 1 - high frequency on a plate glass - 05:46 "Seven piezo ceramic discs are connected with an sine wave generator - and the discs are on a plate glass. Same frequency is output to the piezo discs The frequency shifts slowly and continuously from 9000hz to 20000hz. Due to this, you can listen various sounds made by high-speed cyclic contact between piezo disc and a plate glass, like a ball dribbles. This recording is a private live performance at my room." Track 2 - top of amplitude - 08:25 "I detected the top and bottom of the amplitude from a certain audio signal by a precious gate device. L channel is top (plus level), R channel is bottom (minus level)." Track 3 - on electromagnetic siren - 05:26 "Output an audio signal to the coil of an 100hz electromagnetic siren. The electromagnetic siren vibrates, so you can listen to the amplitude changes according to an audio signal on R c
