摘要：
With stereo audio stepping into people's daily lives, spatial parametric technology comes to its broad prospects for development. This paper provides the audio bandwidth extension encoding and decoding devices, the bitrate of less high-frequency signal reconstruction, in order to improve the quality of the output audio signal. This research makes a contribution to the lack of existing technology, audio bandwidth extension encoding and decoding devices, digital audio decoding to take advantage of a lower bit rate to restore the original audio signal in the digital encoding process the loss of high-frequency components, thereby enhancing the sound playback quality.
