What is UAT | The Most Powerful Audio Codec

UAT is a new audio coding method based on DCT. First, it can quickly identify the type of signal and select the appropriate encoding mode through intelligent analysis. Then do quantization according to the specified bitrate. The trebles are preserved as much as possible in the process of quantization.

There is a dynamic transmission optimization can be performed for different genres and more bandwidth resources are allocated to some specific frequency bands to get more detail. 

Entropy coding is performed after the quantization and then pack the code and side information to one stream for transmission. In addition, UAT also has a noise level detector which can effectively remove the noise existing in the original audio, making the transmission more efficient. 


Every country has its own national headgear. The United States has the baseball cap, Britain is famous for the London bobby's helmet. Greece is associated with the fisherman's hat, while the beret is the symbol of France. The Israelis use the yarmulke and we usually see the Saudi Arabians in their white headdresses. Indian Sikhs wrap their heads in elaborate turbans while Russians warm their craniums with fur hats, which are of good use even at fifty Degree Celsius below zero. In Vietnam, the national chapeau is the non, or conical peasant hat. Along with the graceful silk ao dai, the non has become a sort of informal Vietnamese national symbol that is recognized worldwide.
