Parametric decoding proceeds on the basis of a core signal and mixing parameters (a) controlling a spatial synthesis stage (150), which is supplied with a downmix signal from a downmix stage (140). A selector (170) controls the components of the decoding system, in steady-state parametric and discrete decoding mode and transitions between these. The downmix stage realizes a projection on the downmix signal based on an n-channel signal, either an n-channel input signal or a core signal padded with neutral values. The downmix stage is active in each time frame in which the input signal represents the audio signal by parametric coding and in at least the first time frame after the last time frame in each episode of parametrically coded time frames."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Smooth configuration switching for multichannel audio","description":"A decoding system (100) reconstructs an n-channel audio signal on the basis of an input signal (A) representing the audio signal either by parametric coding or as n discretely coded channels.
