| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Our goal is to develop measurement and analysis method of perceptible difference of sound quality and nuance. In this study, we proposed and examined the method of time domain audio signal analysis from the viewpoint of difference of audio signal amplitude for each amplitude and slope. From results, the proposed method detected the difference of waveforms occurred by operating time of audio equipment. In addition, three dimensional visualizations of the amplitude differences enabled to show the non-linear transformation of waveforms between four types of interconnect cables as shapes and position of the lines in the 3D plot. It is also shown slight differences when AC power with 3rd harmonic voltage supplied to the audio equipment. | |
