    • In an audio signal processing device, an acquisition unit acquires an audio signal. A signal processing unit applies predetermined signal processing to the audio signal acquired by the acquisition unit when the signal processing unit is supplied with power, and outputs the audio signal. A communication unit establishes wireless communication with a communication device for connection to the communication device. A communication controller controls the communication unit to commence the connection to the communication device by the wireless communication when a predetermined connection condition is satisfied, and to sever the connection to the communication device when a predetermined disconnection condition is satisfied. A power control unit starts supply of power to the signal processing unit when the connection to the communication device is commenced, and stops the supply of power to the signal processing unit when the connection to the communication device is severed.
    • 在音频信号处理装置中,获取单元获取音频信号。 当信号处理单元被供电时,信号处理单元对由获取单元获取的音频信号应用预定的信号处理,并输出音频信号。 通信单元与用于连接到通信设备的通信设备建立无线通信。 当满足预定的连接条件时,通信控制器控制通信单元通过无线通信开始与通信设备的连接,并且当满足预定的断开条件时,断开与通信设备的连接。 当与通信设备的连接开始时,电源控制单元开始向信号处理单元供电,当与通信设备的连接断开时,停止向信号处理单元供电。
