Abstract: Provided is a method for detecting an audio input interface, comprising: acquiring input signals of every one of audio input interfaces; acquiring energy values of said input signals of every one of said audio input interfaces, and acquiring an interface identification of the audio input interface of which the energy value is the maximum among the energy values; adding said interface identification acquired herein into an identification sequence in an order by acquiring time; and identifying the audio input interface, of which the interface identification is saved most often in said identification sequence, as a valid audio input interface. Also provided is a system for detecting an audio input interface. The present disclosure is capable of effectively identifying the audio input interface connected to the microphone that the user is using, so that the user does not need to switch manually.

Abstract: Audio encoding methods/terminals, audio decoding methods/terminals, and audio codec systems are provided. A plurality of audio signals that are continuous is obtained. It is determined whether each audio signal of the plurality of audio signals includes a designated signal type, according to an audio parameter of each audio signal. A marked audio encoding stream is obtained by performing a marking to each audio signal as having or not having the designated signal type. The marking is used, at a decoding terminal, to perform an enhancement-process to one or more audio signals having the designated signal type. The enhancement-process is not performed to audio signals that do not have the designated signal type.

Abstract: Methods, apparatus, and systems for voice processing are provided herein. An exemplary method can be implemented by a terminal. A voice bit stream to be sent can be obtained. Voice control information corresponding to the voice bit stream to be sent can be obtained. The voice control information can be used for a voice server to determine a voice-mixing strategy. The voice bit stream and the voice control information can be sent to the voice server. At least one voice bit stream, returned by the voice server based on the voice-mixing strategy, can be received. The at least one voice bit stream can be outputted.

Abstract: The present disclosure discloses a method and system for sending media data in telepresence technology. By collecting audio or video data corresponding to a spatial area, the collected data is processed respectively to acquire multiple streams of data distinguished by a collecting spatial area and corresponding collecting spatial information; the multiple streams of data are encoded, encoded multiple streams of audio data and the collecting spatial information are packed together, and/or encoded multiple streams of video data and the collecting spatial information are packed together, and a packet including multiple streams of audio or video data is sent, respectively. The present disclosure also discloses a method and system for playing media data in telepresence technology. With the methods and systems, it is possible to directly identify the corresponding collecting spatial area, i.e.
