ABSTRACT:
An improved method for correcting errors in a sequence of digital audio data for use in a system having a compact disc player device and a digital signal processor. A compact disc player device reads a compact disc and outputs digital audio data as a series of digitized samples and detects erroneous samples. An error correction apparatus implements a finite impulse response filter. The method achieves a low level of interpolation error within the corrected output of the finite impulse response filter by assigning zero-valued filter coefficients to digital audio samples that are likely to be erroneous due to their proximity to a known erroneous digital audio sample.
