1. A method of reproducing a sound signal, the method comprising:
- generating an output sound signal to be transmitted to speakers by transmitting a first input sound signal through a filter;
acquiring magnitude information of the output sound signal;
determining frequency response parameters related to frequency responses of the filter based on the magnitude information; and
adaptively adjusting coefficients of the filter based on the determined frequency response parameters.
