Parametric Stereo Implementation in DRM System

摘要：

Parametric Stereo is a state-of-the-art stereo coding method. It can efficiently encode a stereo audio signal into two parts including a monaural signal and small amount of stereo parameters. In this paper, the implementation of Parametric Stereo in Digital Radio Mondial (DRM) system is presented. And the difference between Parametric Stereo in DRM and MPEG-4 is also discussed. Using parametric stereo, the efficiency of the audio encoder with scalable bit rate in DRM transmitter can be significantly improved. Experiment results indicate more than 33% of the total bit rate can be reduced while the audio quality maintains the same.
