Abstract

The invention discloses an audio signal processing method and device, relates to the field of signal processing, and solves the problem of how to adjust an output signal according to the change of head rotation of a listener or / and the change of position movement of the listener and improve the auditory effect of the listener. According to the specific scheme, the method comprises: obtaining a current position relationship between a sound source and a listener at a current moment; determining a current audio rendering function according to the current position relationship; if the current position relationship is different from the stored previous position relationship, adjusting the initial gain of the current audio rendering function according to the current position relationship and theprevious position relationship to obtain the adjusted gain of the current audio rendering function; determining an adjusted audio rendering function according to the current audio rendering functionand the adjusted gain; and determining a current output signal according to the current input signal and the adjusted audio rendering function. The embodiment of the invention is used for an audio signal processing process.

Description

technical field [0001] The embodiments of the present application relate to the field of signal processing, and in particular, to an audio signal processing method and device. Background technique [0002] With the rapid development of high-performance computers and signal processing technology, people have higher and higher requirements for voice and audio experience, and immersive audio can meet people's needs in this regard. For example, the application of 4G / 5G communication voice, audio service and virtual reality (virtual reality, VR) has received more and more attention. An immersive virtual reality system requires not only shocking visual effects, but also realistic auditory effects. Audio-visual fusion can greatly improve the experience of virtual reality. At the heart of VR audio is 3D audio. At present, the playback method is usually used to realize the three-dimensional audio effect. For example headphone based binaural playback methods. In the prior art, whe...
