Abstract
Disclosed is an audio signal processing device. The audio signal processing device includes a receiving unit configured to receive a first audio signal corresponding to a sound collected by a first sound collecting device and a second audio signal corresponding to a sound collected by a second sound collecting device, a processor configured to process the second audio signal based on a correlation between the first audio signal and the second audio signal, and an output unit configured to output a processed second audio signal. The first audio signal is a signal for reproducing an output sound of a specific sound object, and the second audio signal is a signal for ambience reproduction of a space in which the specific sound object is positioned.
