ABSTRACT:
Apparatus for reproducing coded audio signals includes interpolation circuitry for substituting interpolated signal values for erred or lost audio signal. To minimize undesirable audible artifacts which may be introduced into the audio signal by virtue of the substitution process, the rate of substitution is monitored. When the rate of substitution exceeds a predetermined rate, the higher frequency components of the audio signal, including the substituted values, are attenuated.
