METHOD AND APPARATUS FOR MASKING ERRORS IN CODED AUDIO DATA Russian patent published in 2013 - IPC G10L19/00 

Abstract RU 2475868 C2

FIELD: information technology.

SUBSTANCE: method of masking frame errors in coded audio data is realised by receiving coded audio data in a plurality of frames. The method is also realised using one or more stored parameter values from one or more previous frames to reconstruct a frame with a frame error. Use of one or more stored parameter values involves obtaining parameter values based, at least in part, on one or more stored parameter values and applying the obtained values to the frame with a frame error.

EFFECT: masking a frame error in order to minimise the number of uncomfortable artefacts, and also supporting perceptible signal characteristics with regard to expansion in frame errors.
