1. a silencing processing device is used for handling quiet that many people talk process produces on the network, it is characterized in that this device comprises:

  • One sampling unit, signal from microphone is used to take a sample;

    One energy calculation unit, be used for computing time at interval in the energy of sampled signal;

    One coding unit is used for the signal of code sample;

    One processing unit, the energy of sampled signal is less than a predetermined power value in a time interval, and have the sampled signal energy in the lasting a plurality of time intervals that reach a predetermined value all less than this predetermined power value before being connected in this time interval, send the sampled signal of quiet frame identification in should the time interval, otherwise, this processing unit control coding unit sampled signal in this time interval of encoding;

    AndOne output unit is used to export the code signal of quiet frame or coding unit generation.
