An apparatus and a method for automatically controlling a gain using phase information are provided. The apparatus includes a frequency conversion unit converting each of input signals received from a plurality of acoustic input apparatuses to frequency input signals, a factor determination unit determining a scaling factor according to a gain difference between the input signals based on a phase difference of the frequency input signals, and a scaling performance unit performing scaling for gain compensation between the input signals based on the scaling factor. |
