Embodiment 1

[0061] Provides a communication method involving audio data, which can be mainly applied as Figure 1a with 1b A communication system containing audio data such as Figure 1a The system shown includes multiple audio sub-sites and mixing equipment, and each audio sub-site includes multiple clients, and one of the multiple clients (such as the first client) will serve as the main machine , the main machine respectively communicates with other clients in the audio sub-conference, and the audio mixing device communicates with these multiple clients respectively ( Figure 1a The communication connection between the mixing device and the non-main machine is not shown). in:

[0062] A client can join an audio sub-site, establish a communication session containing audio data with other clients, and communicate with other clients containing audio data. The communication containing audio data can be pure audio data communication, or It is communication of video data, etc. The client i...

Embodiment 2

[0097] Provides a communication method involving audio data, which can be mainly applied as Figure 1a with Figure 1b In the shown communication system containing audio data, the method of this embodiment is a method executed by a second client as a non-main machine in a certain audio sub-site (such as the first audio sub-site) in the system, the flow chart Such as Figure 4 shown, including:

[0098] Step 201, establish a first communication link with a host computer in a first audio sub-conference.

[0099] It can be understood that the user can operate the second client to make the second client join a certain audio sub-conference (such as the first audio sub-conference), for example, by "shaking" or "face-to-face group building" The user operates an instruction so that the second client joins the first audio sub-conference together with other audio communication clients. In this embodiment, the multiple clients joining the same audio sub-conference site are mainly clie...

Embodiment 3

[0116] Provides a communication method involving audio data, which can be mainly applied as Figure 1a In the communication system containing audio data shown, the method of this embodiment is a method performed by the sound mixing device in the system, and the flow chart is as follows Figure 5 shown, including:

[0117] Step 301, respectively determine main machines of multiple audio sub-sites.

[0118] Specifically, when the audio mixing device determines the main computer of an audio sub-conference (such as the first audio sub-conference), it can determine it according to the average network delay from each client of the audio sub-conference to other clients. The audio device can separately obtain the average network delay from each client in the first audio sub-conference to other clients, if the average network delay from the first client to other clients in the first audio sub-conference Small, determine the first client as the host computer of the first audio sub-conf...

Abstract

An embodiment of the invention discloses an audio frequency data communication method, device and system and belongs to the technical field of communication. First communication links between a main device in a first audio frequency sub-meeting-place and other client ends in the first audio frequency sub-meeting-place are respectively established; via the first communication link, first sound mixing signals that are received are sent to the other client ends in the first audio frequency sub-meeting-place, and the other client ends are enabled to receive the first sound mixing signals synchronously; if the first sound mixing signals are played later than the time when the first sound mixing signals are received by the main device, then the first sound mixing signals tend to be played synchronously by all client ends in the first audio frequency sub-meeting-place, the first sound mixing signals are sound mixing signals of audio frequency signals of other audio frequency sub-meeting-places, a problem that audio feedback squeal and desynchrony are caused when sound of the audio frequency sub-meeting-place is played in the same audio frequency sub-meeting-place can be prevented, and mobile terminals such as mobile phones and the like can be used as client ends in each audio frequency sub-meeting-place.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication method, device and system including audio data. Background technique [0002] Audio conferencing has a very wide range of application requirements in office and life, so that users in different regions can use their own conference terminals to join in the same audio conference for conversations, which solves the problem of multi-person voice communication in different regions. Typical scenarios Many people use one conference terminal in the same venue (for example, a meeting room) to communicate with remote venues. This scenario puts forward two requirements for the conference terminal: the playback volume of the conference terminal is high enough to allow people in the venue to listen. At the same time, the sound pickup effect of the conference terminal must be particularly good, because the straight-line distance between the speakers in the venue a...
