EN The paper presents a very simple enhancement of joint coding of stereo and surround channels within a perceptual audio codec. Moreover, the paper proposes two improvements to standard parametric stereo and spatial audio compression in order to avoid the smearing of transients in the process of channel downmixing. The improvements consist in compensating of inter-channel delays prior to mixdown, as well as additional encoding of the room response for realistic reconstruction of the stereo ambience.
