Abstract
Disclosed is an audio signal processing device including a processor for outputting an output audio signal generated based on an input audio signal. The processor may be configured to obtain a first pair of head-related transfer function (HRTF)s including a first ipsilateral HRTF and a first contralateral HRTF based on a position of a virtual sound source corresponding to the input audio signal, from a first set of transfer functions including HRTFs corresponding to each specific position with respect to listener, and generate the output audio signal by performing binaural rendering the input audio signal based on the first pair of HRTFs.
