AB  - Parametric stereo coding in combination with an efficient coder for the underlying monaural audio signal results in the most efficient coding scheme for stereo signals at very low bit rates available today. While techniques for lateral localization have been studied since early intensity stereo coding tools, synthesis of stereophonic ambience was only recently applied in parametric stereo coding systems. This paper studies different techniques for synthetic ambience generation in the context of parametric stereo coding systems and discusses their mono-compatibility. Implementations of these techniques in combination with mp3PRO and aacPlus are presented together with experimental results.
