Audio playing method and device based on sound source localization, projection equipment and medium

Abstract

The invention discloses an audio playing method and device based on sound source localization, projection equipment and a medium, and relates to the field of audio playing. The audio playing method based on sound source localization comprises the following steps: sequentially playing audio data of each channel, acquiring sound emitted by a sound box corresponding to each channel through a microphone array, and measuring and calculating the spatial position of the sound box corresponding to each channel; determining the relative positions of the sound boxes according to the spatial positions ofthe sound boxes; and setting an audio stream data format according to the relative positions of the sound boxes. According to the application, the audio stream data format is set according to the sound box position, so that the audio stream data format conforms to the sound box placement position of the user, even if the user places the sound box wrongly, the position of the sound box does not need to be readjusted, and the original effect of the multi-channel sound box system can also be realized or basically realized. Moreover, according to the position of the sound box, the sending time ofthe corresponding sound box data in the audio stream data format is changed, the audio data synchronization is ensured, and the user experience is improved.

Description

technical field [0001] The present application relates to the field of audio playback, and in particular to an audio playback method, device, projection device and medium based on sound source localization. Background technique [0002] With people's pursuit of high-quality audio and video playback, multi-channel speaker systems are gradually becoming popular, such as 5.1 speakers and 7.1 speakers. A multi-channel speaker system usually includes a plurality of speakers, and the user needs to place the plurality of speakers in corresponding positions in order to achieve an ideal auditory effect. Because the appearance of some speakers in the multi-channel speaker system is basically the same, it is difficult for users to identify them. During installation, users may misplace the speakers, which will affect the hearing effect. Taking 5.1 speakers as an example, it usually consists of L (front left), R (front right), Ls (rear left), Rs (rear right), Lfe (bass) and C (center) s...
