Audio generation method and device, computer equipment and storage medium

Abstract

The invention relates to an audio generation method and device, computer equipment and a storage medium. The method can be applied to an application scene for generating an audio in a map navigation process, and comprises the following steps: based on a distance value between a sound source and a target object, performing distance sensing processing on an audio signal of the sound source to obtain a distance sensing audio signal; performing sound mixing processing on the distance sensing audio signals of the sound sources in the same grid area to obtain sound mixing audio signals corresponding to each grid area; determining a sound image center based on the position information and the audio weight value of each sound source in the grid area; based on the sound image center, carrying out stereo reconstruction on the sound mixing audio signal of the grid area, and acquiring a stereo audio signal; and respectively carrying out sound mixing processing on the left channel audio signals and the right channel audio signals of all the stereo audio signals to obtain stereo sound mixing audio signals. By adopting the method, the calculation overhead for generating the stereo audio signal can be effectively reduced.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to an audio generation method, device, computer equipment and storage medium. Background technique [0002] With the development of computer technology and Internet technology, the realization of Metaverse requires artificial intelligence virtual perception technology that integrates audio, video, perception and other aspects to construct a computer virtual space that is close to the perception of the real world. Experiencers use some hardware devices (such as Headphones, glasses, somatosensory equipment, etc.), you can experience the same sensory experience as the real world. [0003] However, in the current audio generation method, when reconstructing virtual space sound effects, in the case of similar metaverse applications, due to the relatively large number of sound sources, there may be dozens or even hundreds of sound sources, and the audio signals of all sound so...

[0003] However, in the current audio generation method, when reconstructing sound effects in virtual spaces, in the case of metaverse applications, due to the relatively large number of sound sources, there may be dozens or even hundreds of sound sources, and the audio signals of all sound sources need to be Stereo reconstruction is carried out separately, and the calculation overhead of stereo reconstruction is relatively large, resulting in a very high calculation overhead for stereo audio signal generation, which makes it impossible for ordinary equipment to complete the real-time calculation requirements. Even if the calculation module is transferred to the server, the stereo Audio signal generation is also very computationally expensive
