Abstract
Methods, apparatuses, decoders, and computer programs for replacing decoded parameters in a received multichannel signal are provided. Multichannel parameters of a frame of the signal are decoded. Responsive to a bad frame being indicated, it is determined that a parameter memory is corrupted. Responsive to a bad frame not being indicated: responsive to the parameter memory not being corrupted, a location measure is derived of a reconstructed sound source based on decoded multichannel parameters. Responsive to the parameter memory being corrupted, it is determined, based on the location measure, whether the reconstructed sound source is stable and predominantly concentrated in a subset of channels of multichannels of the received multichannel signal. Responsive to the reconstructed sound source being concentrated in the subset of channels of the multichannels and being stable, parameter recovery is activated to replace decoded multichannel parameters with stored multichannel parameters.
