Abstract
A signal processing apparatus and a signal processing method are provided. In a case where an HS microphone detection circuit has just detected connection of a microphone contact point, an input and output IF blocks a sound signal which is input from the microphone contact point from a first input port of a sound processing apparatus for two seconds by an HS mute circuit. Thereby, it is possible to prevent an improper sound signal from the microphone contact point from being output from a left speaker and a right speaker of a headset through a right output port Rout and a left output port Lout of the sound processing apparatus. Therefore, it is possible to prevent unpleasant noise caused by the improper sound signal from being output to a user.
