Device and method for sending and receiving audio data stream

Abstract

The invention discloses a device and a method for transmitting and receiving audio data streams. The device comprises a processing module, a coding module and a transmitting module, wherein the processing module is used for dividing current acquired audio data streams to be transmitted, filtering the audio data streams according to mute data streams in various sections of divided data streams and recording position information of the filtered data streams in the audio data streams to be transmitted; the filtered data streams are determined by energy values of the various sections of divided audio data streams; the coding module is used for coding the audio data streams which are processed by the processing module; the transmitting module is used for transmitting the audio data streams processed by the coding module and indication information; and the indication information has the position information of the filtered data streams recorded by the processing module in the audio data streams to be transmitted. By the technical scheme, call quality is improved by eliminating noise data, and network flow and power consumption of a mobile terminal are reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a device and method for sending and receiving audio data streams. Background technique [0002] At present, voice instant messaging has been widely used in many aspects, such as instant messaging software such as QQ and Fetion, SKYEP Internet phone software that can be used for long-distance calls at home and abroad, and various other audio and video chat software. In these applications, the call quality will be affected by the network environment and hardware configuration, especially in the mobile terminal-based VoIP (Voice over IP, VOIP) network telephony applications. Since the mobile terminal network used by most people in our country is still in the GPRS communication in the 2G era, and the hardware configuration of the mobile terminal is low, the call quality is poor. Despite the rapid development of 3G and WIFI networks today, severe network congestion often occurs due...
