Abstract
A method, apparatus and decoder for replacing decoded parameters in a received multichannel signal in which a frame of consecutive frames of the received multichannel signal is decoded and responsive to receiving a previous frame bad frame indicator while operating in a predictive decoding mode with a current frame of the consecutive frames, it is determined whether a parameter stability measure is below a threshold. Responsive to the parameter stability measure being below the threshold a parameter recovery is activated by retrieving the estimated parameters and replacing decoded parameters of the current frame with the estimated parameters. Otherwise, it is detected whether a source is an active source and responsive to the source being an active source, decoded parameters of the current frame are stored as estimated parameters and the parameter stability measure is determined.
