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.
