Abstract
Disclosed is an audio signal processing device that estimates a room impulse response (RIR) filter of a space. The audio signal processing device may include a processor. The processor receives an input signal, and estimates, from the received input signal by using a machine learning model, an RIR filter representing a characteristic of a response transferred to a listener from a sound source located in a predetermined location in a space where the input signal is collected, wherein the predetermined location is a relative location determined based on the listener, wherein the machine learning model is trained to estimate a reference RIR filter from signals response associated with a reference RIR filter corresponding to the predetermined location and a plurality of additional RIR filters that represent characteristics of responses transferred to the listener from sound sources located in a space represented by the reference RIR filter.
