A method for extrapolating missing or corrupted samples in a digital audio data stream is presented. The method involves spectral extrapolation to synthesize an estimate of the missing material using a sinusoidal representation. The method takes advantage of the relatively slow variation in the time-variant spectral amplitude envelope in comparison with the relatively rapid oscillations of the time-domain signal. Examples and applications are : considered.
