Abstract: A method of frame error concealment in encoded audio data comprises receiving encoded audio data in a plurality of frames; and using saved one or more parameter values from one or more previous frames to reconstruct a frame with frame error. Using the saved one or more parameter values comprises deriving parameter values based at least part on the saved one or more parameter values and applying the derived values to the frame with frame error.

Abstract: An apparatus comprising a mapper configured to map an instance of a parameter according to a first mapping to generate a first mapped instance; a remapper configured to remap the first mapped instance dependent on the frequency distribution of mapped instances to generate a remapped instance with an associated order position; and an encoder configured to encode the remapped instance dependent on an order position of the remapped instance.
