Title:
SOUND FIELD EXPANSION METHOD, AUDIO DEVICE, AND COMPUTER READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/067782
Kind Code:
A1
Abstract:
The present application discloses a sound field expansion method, an audio device, and a computer readable storage medium, and belongs to the technical field of audio processing. The sound field expansion method provided by the present application comprises the following steps: obtaining a target transfer function between a near-ear open-type audio device and the two ears of a user; according to the target transfer function, performing crosstalk elimination processing on input audio received by the near-ear open-type audio device, obtaining initial reverberation audio; identifying an actual sound intensity weight ratio between human voice audio and accompanying audio in the initial reverberation audio; according to the actual sound intensity weight ratio, adjusting the sound intensity of the human voice audio and/or the accompanying audio in the initial reverberation audio, to obtain target reverberation audio; playing the target reverberation audio by means of the near-ear open-type audio device. The audio device of the present application can effectively expand a sound field while ensuring the sound effect of a human voice.
