Method and apparatus for restoring audio error data and digital audio signal processor using thereof

摘要

The method involves adding a number of erroneous samples based on a number of error flags. A value obtained by adding a product of two normal sample values and two weights is calculated, when one erroneous sample is added between two normal samples. Another value located on a continuous line of one of the samples is calculated. A mean value of the values is set to a sample value of a position where the erroneous sample exists. Independent claims are also included for the following: (A) an audio error correcting apparatus to interpolate erroneous samples (B) a computer readable medium to correct errors in an audio signal.
