Abstract: An audio signal rendering method includes obtaining a to-be-rendered audio signal by decoding a received bitstream, obtaining control information, where the control information indicates at least one of content description metadata, rendering format flag information, loudspeaker configuration information, application scene information, tracking information, posture information, or location information, and rendering the to-be-rendered audio signal based on the control information to obtain a rendered audio signal.

Abstract: An apparatus provides personalized binaural audio rendering of an input signal. The apparatus has a left ear transducer configured to generate a left ear audio signal and a right ear transducer configured to generate a right ear audio signal. Moreover, the apparatus has processing circuitry configured to determine, based on a current target direction of the input signal, an adjusted current target direction using a personalized adjustment function that describes a functional relationship between a plurality of reference target directions of a reference sound signal and a plurality of perceived reference target directions of the reference sound signal as perceived by a user. The processing circuitry is further configured to implement a target direction renderer configured to generate based on the input signal and the adjusted target direction a first driving signal for driving the left ear transducer and a second driving signal for driving the right ear transducer.
