Volume limiting method and system

Abstract

This invention relates to volume limit method and system, wherein, the method comprises the following steps: Firstly processing the receive end sound sample point resonance data to get one relative intensity value; then judging whether the relative intensity is over standard; finally adjusting the relative intensity near one standard value. The said conversion operation is to express the sample point by relative value. The said system comprises signal collector, A / D converter, processor and D / A converter, wherein, the said parts are connected in order. The advantages of this invention are the following: the method can effectively control the limit volume to ensure the processed volume quality.

Description

Technical field [0001] The present invention relates to broadcast communication technology, and in particular to a method and system for volume limitation. Background technique [0002] In a video conferencing system, the destination client usually receives voices from multiple source client terminals, and the different-source client terminal often causes the destination client terminal to hear sounds of different volume due to the different volume settings of their PCs. In order to hear the voice of the source client at the lowest volume, the destination client usually increases the local system volume. In a meeting, if the local system volume of some source clients is relatively high, it will cause the destination client to have too high volume, thereby affecting the user's hearing effect. This situation occurs in all systems that use volume control, so it is necessary to perform volume limit operations on the destination user side. [0003] At present, the solution for volume ...

Problems solved by technology

[0004] The disadvantage of the above scheme is firstly: when judging whether to adjust the volume, the absolute amplitude value data of the sample point is directly compared with an optimal value, which cannot truly reflect the effect of the volume level felt by the human ear, because the human ear auditory responses are based on relative changes in sound, not absolute changes

Secondly: when adjusting, the amplitude value data of the source sample point is directly multiplied by a coefficient as the adjusted output. This linear adjustment cannot achieve the real auditory experience of the human ear.
