The evolution of the next Generation network is mainly based on two routes: the first route is mainly embodied in the transfer of the traditional telecommunication service from the dedicated TDM bearer to the unified shared IP/ATM network, and the network layer service transmission is grouped under the precondition of maintaining the user access mode unchanged. The original circuit switching network equipment is divided into two parts: the physical independent control surface soft exchange and t

There are two types of audio recording in Android: audiorecord and mediarecorder. The former is suitable for real-time processing of audio data.
