ADVANCES IN PARAMETRIC CODING FOR HIGH-QUALITY AUDIO

Compared to traditional waveform coding standards that employ subband or transform coding, parametric coding is regarded as a technique that allows even further reduction of bit rates. In response to a call for proposals by MPEG-4 in January 2001, Philips submitted a parametric coder targetting at a high quality level. Currently, this coder is improved in the course of the “MPEG-4 Extension 2” standardisation process. Recently, two enhancements have been made increasing the overall performance of the coder. These consist of an improved model for the noise object and a parametric stereo extension.
