Codieren und Decodieren von Audiosignalen unter Verwendung von Intensity-Stereo und Praediktion

The method involves grouping of the stereo audio spectral values in scale factor bands, before coding via an intensity-stereo method, so that one channel carries the intensity-stereo coded stereo audio spectral values and the other channel carries stereo audio spectral values equal to zero. The intensity-stereo coded stereo audio coded values are decoded for each scale factor band and a prediction method is used to provide the coded stereo audio spectral values for the other channel. ADVANTAGE - Reduced bit rate for increased data transmission rate without impaired quality.
