AUDIO COMMUNICATION SYSTEM, TRANSMITTER, RECEIVER, AND ITS METHOD

摘要

PROBLEM TO BE SOLVED: To provide an audio communication system which can determine the start and end of an audio signal to be acquired accurately with a simple configuration.

SOLUTION: When an audio transmission button is pressed, a transmitter generates a stereo signal generation signal based on an audio signal inputted from a user and a reference signal indicating a detection zone of the audio signal and transmits the generated signal. The receiver determines an acquisition zone of the audio signal based on the reference signal detected from the received generation signal and then acquires the audio signal based on the determined acquisition zone.
