Abstract: Provided are an audio signal processing system including a speaker and a microphone and an echo signal removing method thereof. The audio signal processing system includes an audio source which receives an audio signal to be outputted to the speaker; an echo signal delay unit which delays, for a bulk delay, an echo signal generated by the audio signal received from the speaker in the microphone and outputs the delayed echo signal; and an echo signal removing unit which removes the echo signal delayed by the echo signal delaying unit from the audio signal received in the microphone. The echo signal delay unit measures the bulk delay by analyzing impulse response properties of an echo path. [Reference numerals] (143) Bulk delay measurement unit; (145) Double talk detecting unit
