An improved technique for processing digital audio signals is provided wherein adaptation of predictor coefficients in an ADPCM environment is caused to converge in a rapid and computationally efficient manner. The technique (fig. 2) employs a whitening filter (218) to generate a filtered reconstructed signal (220) which is utilized to update, or adapt, the prediction coefficients of a pole-based predictor (210).
