Problems solved by technology

However, in this technical solution, algorithmic reverberation is mainly used to simulate the late reverberation effect of audio, so that the output audio signal has a certain sense of space.
However, the algorithmic reverberation is still difficult to simulate the sense of space corresponding to the specific scene displayed by the VR appl...

Abstract

The application relating to the technical field of virtual audios of VR discloses an audio processing method and apparatus, and a terminal device so that the VR audio effect provided by the VR devicecan match the spatial sense of the VR visual effect displayed by the VR application to the user. The audio processing method comprises the following steps that: according to audio sound channel information in original audio data, the original audio data are virtualized by using a head related transfer function (HRTF) database; sampling reverberation data corresponding to the location selected by the user are selected from a sampling reverberation database, wherein the sampling reverberation database includes sampling reverberation data corresponding to the location in a scene displayed by theVR application; reverberation convolution processing is carried out on the virtualized audio data by using the sampling reverberation data corresponding to the location selected by the user; and soundmixing is carried out on the virtualized audio data after reverberation convolution processing and binaural audio data are generated. The audio processing method and apparatus, and the terminal device are applied to audio processing.

Description

Technical field [0001] This application relates to the virtual audio technology field of VR (Virtual Reality, virtual reality), and in particular to an audio processing method. Background technique [0002] VR is a technology that uses computer graphics, sound systems, and various reality and control interface devices to provide immersive experience in an interactive three-dimensional environment generated on a computer. Currently, research in the field of virtual reality is very extensive. Among them, the experience of virtual audio in VR is getting more and more attention. [0003] Currently, when using a VR device, the VR application opened by the user will usually show the user some audio and video effects that simulate the real environment through the VR device. Among them, the audio effect provided by the VR device mainly uses the HRTF (Head Related Transfer Function) technology to achieve the effect of simulating real environment audio. However, this kind of processing tec...
