To achieve CD quality (16bit/44.1khz stereo) need 1411.2 kbit/s bandwidth, obviously Bluetooth A2DP cannot allow (Bluetooth 2.0/2.1 + EDR The largest carrier rate is about 2.1mbit/s, minus the protocol header, interference, power dissipation factor influence , the actual maximum transfer rate is approximately 1000bit/s), so the audio data needs to be compressed. We know that the same bit rate, different encoding format compression rate is different, thus decoding the quality of the restoration i

Session Border controller (SBC) is a standard configuration product for NGN and IMS networks.SBC is generally located between two service provider networks in a peer environment, or between an access network and a backbone network that provides services to residents and enterprise users. Although some SBC only process signaling, m

The basic idea of the Subband encoding (Subband CODING,SBC) is to use a set of Bandpass filters (Band-pass FILTER,BPF) to divide the frequency band of the input audio signal into several successive bands, each of which is called a subband. A separate coding scheme is used to encode the audio signals in each sub-band. When transmitting on a channel, the code of each child band is composited together. At the receiving end of decoding, the code of each

Preface:
The Android simulator that we are developing now simulates arm's architecture (Arm-eabi), so the simulator is not run on x86, but the arm is simulated, so we often feel very slow when we debug the program, most developers should have a deep understanding.
In this case, I
