Audio signal processing method and device
An audio signal processing apparatus including a receiving unit receiving an input audio signal, a processor generating an output audio signal reproducing a virtual sound source corresponding to the input audio signal in a virtual space, and an output unit outputting an output audio signal generated by the processor is disclosed. The processor may obtain spatial information related to the virtual space including a virtual sound source corresponding to the input audio signal and a listener, filter the input audio signal based on a location of the virtual sound source and the spatial information to generate at least one reflected sound corresponding to each of at least one mirror plane in the virtual space, obtain a relative location of a virtual reflect sound source with respect to a location and a view-point of the listener, based on information of the view-point of the listener and a location of the virtual reflect sound source corresponding to each of the at least one reflected sound, and binaural render the at least one reflected sound, based on the relative location of the virtual reflect sound source corresponding to each of the at least one reflected sound.
