Abstract

The invention discloses a recording data training method, a multi-track audio surrounding method and a recording data training device, and belongs to the field of audio processing. The recording data training method comprises the following steps: according to an hearing environment of a user, modeling to obtain a virtual hearing model; according to physiological data of the head of the user, modeling to obtain a virtual dummy head model; calculating to obtain interaural time difference (ITD) corresponding to direct waves of each sound track; calculating to obtain interaural latency difference (ILD) corresponding to direct waves of each sound track. The multi-track audio surrounding method comprises the following steps: obtaining original multi-track audio content; according to the ITD and the ILD obtained by the recording data training method, performing conversion on sound data of each sound track in the multi-track audio content to obtain left channel data and right channel data which correspond to each sound track; mixing the left sound channel data corresponding to each sound track into target left channel data and mixing right sound channel data corresponding to each sound track into target right sound channel data to generate stereo audio content.

Description

technical field [0001] The invention relates to the field of audio processing, in particular to a recording data training method, a multi-track audio surround method and a device. Background technique [0002] The multi-track audio content refers to 5.1-channel audio content, 7.1-channel audio content, and the like. Multi-track audio content can enable users to listen to audio from different directions to form a surround sound effect. [0003] Taking 5.1-channel speakers as an example to play 5.1-channel multi-track audio, the user can simultaneously listen to the sound from the front left speaker, center speaker, front right speaker, rear left speaker, rear right speaker and subwoofer The sound played by a total of 6 speakers increases the sense of space of the sound and can produce the effect of surround sound. [0004] In the process of realizing the embodiment of the present invention, the inventors found that the above-mentioned technology has at least the following p...
