Abstract

The invention provides a method and a system for extracting sound. The method includes: various types of sound transmitted by a client are received by a server, sound information of the sound is saved to a sound source table in the server, and an inquiring request is transmitted to a controller; corresponding grade coefficient of the sound is inquired in a local comparison table of sound types and grades after the inquiring request is received by the controller, corresponding bandwidth coefficient of the sound is inquired in a local comparison table of sound bandwidth coefficient according to actual bandwidth bearing the sound, and an inquiring result is returned to the server. Sampling rate of all sounds in the sound source table is determined according to the corresponding grade coefficient and bandwidth coefficient of the sound. The sounds, which are identical in sampling rate with appointed sampling rate of a user, in the sound source table are added to a target sound table in the server, and the sounds in the target sound table are processed.

Description

technical field [0001] The invention belongs to the field of instant communication, and in particular relates to a sound extraction method and system. Background technique [0002] With the rapid development of the information society, various instant communication methods such as QQ and video conferencing are more and more widely used. During the use of the web video conference, there are often various sounds from different sources. If there are different types of sounds in the web conference, it will seriously affect the quality of the web call. Therefore, how to capture and filter out the desired sound has become a hot issue in the industry. In addition, in daily applications, due to the limitations of the network environment and how to distinguish different types of sounds, the sound screening process is affected by many factors. How to reasonably and effectively achieve the best results required by users has become a problem that needs to be solved . Contents of the...
