Physical characteristics of analog audio cables and their effect on sound quality
This paper deals with the change in sound quality due to an analog audio cable under a high impedance load. It has been quantitatively shown that the signal amplitude dependency of the time constant affects the audible sound quality. Under the handling conditions, a change in the capacitance of the cable due to the signal causes a change in the sound quality. Then, the transient response and the sensitivity of the capacitance change due to the signal were measured for some cables. In addition to showing the characteristics of each cable, we propose conditions that hardly affect sound quality.
