Method and device for audio signal mixing processing
An audio signal and processing method technology, applied in the field of communication, can solve the problems of overlapping audio signal orientation, reducing the user's sense of presence experience, and the user's inability to listen to the voice signal clearly, achieving the effect of clear sound and improving the sense of presence experience.

Embodiment 1
[0042] Embodiment 1 is the audio mixing process when there are sites with overlapping audio signals in the largest N-party sites participating in the audio mixing. The audio mixing process is as follows: Figure 5 As shown, the specific implementation includes the following operations:
[0043] S501. The MCU detects the audio signal orientation (hereinafter referred to as: orientation) of the largest N-party venue to be mixed;
[0044] Among them, since the monophonic conference site itself has no orientation, the orientation of the conference site is specified externally (specifically, it can be specified by the MCU, user specified, etc.), and for the dual-channel or multi-channel conference site, in addition to the externally specified In addition to the orientation, it can also be the actual orientation detected based on the data of the venue itself.
[0045] A preferred way is as follows:
[0046] Binaural and multi-channel venue orientation detection methods: Generally ...
Embodiment 2
[0081] Embodiment 2 is the audio mixing processing process when there is a conference site inconsistent with the orientation in the video picture among the largest N conference sites participating in the audio mixing. The audio mixing processing process is as follows: Figure 6 As shown, the specific implementation method includes the following operations:
[0082] S601. The MCU detects whether the orientation of each venue in the largest N-party venue is consistent with its orientation in the video screen, if yes, execute S602, and if not, execute S603;
[0083] S602. The MCU performs mixing processing on the audio signals from the largest N-party venue. The specific implementation method of the mixing processing can be realized through the existing mixing method, and will not be described in detail here;
[0084] S603. The MCU adjusts the orientation of the conference site according to the detected position in the video screen of the conference site whose orientation is inco...
Embodiment 3
[0091] Embodiment 3 is the audio mixing process when the conference site at the receiving end specifies the orientation for the largest N-party conference site. The audio mixing process is as follows: Figure 7 As shown, the specific implementation method includes the following operations:
[0092] S701. The MCU receives the orientation designation information sent by the venue n. The orientation specification information is used to instruct the MCU to adjust the orientation of the venue a in the largest N-party venues. As an example and not a limitation, the orientation specification information can be sent by signaling ;
[0093] S702. The MCU adjusts the orientation of the venue a to the orientation specified in the above orientation specifying information. Wherein, the location designation information may also carry designated validation information, which is used to indicate that the location information is to be adjusted for site a only when the audio mixing is sent to ...
