An apparatus and a method for providing audio of plural channels by using a human hearing characteristic are provided to supply audio of plural channels at the same time to prevent a user from being disturbed by another audio channel. An audio strength comparison unit calculates and compares strength of a main channel audio signal and strength of a sub channel audio signal. The audio strength comparison unit calculates an adjustment value of the strength of the sub channel audio signal. A gain controlling unit adjusts the strength of the sub channel audio signal. |
