Abstract
Appropriate control corresponding to an ambient sound situation is executed for an audio processing system which receives an input of a sound via a microphone and outputs the sound via a speaker. For this purpose, a controller for the audio processing system which receives an input of a sound via the microphone and outputs the sound from the speaker includes a characteristic control unit and an analysis unit. The characteristic control unit is capable of selectively executing a plurality of control methods as an audio signal characteristic control method. The analysis unit analyzes the sound input via the microphone, and selects a control method executed by the characteristic control unit for the audio processing system in accordance with an analysis result.
