Abstract

The embodiment of the invention discloses an audio processing method applied to first terminal equipment with at least two audio channels. The first terminal device is communicated with at least one second terminal device. The method comprises the following steps: the first terminal device receives the remix audio transmitted by the at least one second terminal device through a transmission channel; the remix audio comprises at least two audio messages mixed together; the remix audio is separated to obtain at least one independent audio message of the remix audio; and one separated independent audio message is output through one audio channel. By applying the audio processing method, one independent audio message can be output and played through one audio channel by placing at least two audio channels on the terminal equipment and separating the remix audio, so that the definition of single audio message can be improved so as to be convenient for users to distinguish.

Description

technical field [0001] The present application relates to the technical field of voice communication, in particular to an audio processing method, terminal equipment and system. Background technique [0002] The existing teleconferencing system includes a plurality of terminal devices with microphones, and these terminal devices are connected to communication networks, such as PSTN (Public Switched Telephone Network, Public Switched Telephone Network), IP (Internet Protocol, Internet Protocol) network and so on. Taking a three-party conference call as an example, one of the terminal devices only needs to provide two lines to connect the other two terminal devices to realize a three-party call. At present, the most common way is that the switchboard provides the three-party call function, or the operator provides the multi-party conference call bridging service, so that people in different places can overcome the difficulties of geographical location or distance, and at the s...
