Embodiment Construction

[0059] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0060] In related technologies, when an audio playback device processes audio data, it completely relies on a pre-stored HRTF database. When the location of the virtual sound source is acquired, the audio playback device searches the HRTF database for the HRTF data collection point that exactly matches it according to the virtual sound source location, and uses the HRTF data correspond...

Abstract

The invention discloses an audio processing method and device, and belongs to the technical field of audio processing. The method comprises the steps of: obtaining a virtual sound source position in a virtual listening environment; detecting whether an HRTF database includes an HRTF data acquisition point matched with the virtual sound source position or not; if the HRTF database does not include the HRTF data acquisition point matched with the virtual sound source position, obtaining a first reference HRTF data acquisition point and a second reference HRTF data acquisition point corresponding to the virtual sound source position from the HRTF database, wherein the virtual sound source position is positioned on a path between the first reference HRTF data acquisition point and the second reference HRTF data acquisition point; according to first HRTF data corresponding to the first reference HRTF data acquisition point and second HRTF data corresponding to the second reference HRTF data acquisition point, calculating target HRTF data corresponding to the virtual sound source position; and, according to the target HRTF data, processing audio data.

Description

technical field [0001] The present disclosure relates to the technical field of audio processing, in particular to an audio processing method and device. Background technique [0002] With the continuous maturity of audio playback technology, people have higher and higher requirements for playback effects of audio playback devices. In order to enable users to experience realistic stereo surround sound effects when listening with headphones, the audio playback device uses HRTF (Head Related Transfer Function) processing technology to process the audio data to be played. [0003] In related technologies, in order to realize the HRTF processing of audio data, developers need to collect a series of HRTF data with the human head as the center of the sphere in the acoustic room through Binaural recording technology in advance, and record the corresponding HRTF data of each piece of HRTF data. The relative position of the data collection point and the human head, so that the HRTF ...
