Abstract
An angle calculator calculates, based on acceleration detected by an acceleration sensor, a tilt angle of a transceiver with respect to the vertical direction. A selector (i) selects a first audio filter to operate if the tilt angle is less than a threshold angle, or (ii) selects a second audio filter to operate if the tilt angle is equal to or greater than the threshold angle. The second audio filter has a lower cutoff frequency that is higher than the lower cutoff frequency of the first audio filter.
