The device may generate a down-mix error concealment frame and transform the frame into a frequency domain to generate a transformed down-mix error concealment frame. The device may decorrelate the transformed frame to generate a decorrelated concealment frame. The device may obtain a residual signal spectrum of a stored residual signal of a previously received multichannel audio signal frame and generate an energy adjusted decorrelated residual signal concealment frame using the residual signal spectrum. The device may obtain a set of multi-channel audio substitution parameters and provide the frames and substitution parameters to an audio synthesis component to generate a synthesized multichannel audio frame. The device performs an inverse frequency domain transformation of the audio frame to generate a substitution frame for the lost or corrupted audio frame."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for controlling multichannel audio frame loss concealment","description":"A method of approximating a lost or corrupted multichannel audio frame of a multichannel audio signal in a decoding device is provided.
