Abstract: Disclosed is an audio signal processing method including identifying a sound source provided inside a preset reference distance and a sound source provided outside the reference distance to represent a sound field based on virtual reality (VR) content that is represented in a predetermined virtual space in which a user is located in a VR environment, processing a sound field using three-dimensional (3D) ambisonics based on height information and horizontal information of the sound source provided inside the reference distance, and processing a sound field using two-dimensional (2D) ambisonics based on horizontal information of the sound source provided outside the reference distance.
