A warped linear-prediction-based subband audio coding algorithm.

A warped linear-prediction-based subband audio coding algorithm.

A novel audio coding algorithm is proposed where the warped-linear prediction (WLP) technique is employed to construct a perceptual pre- and post-filter for subband audio coding. A modified signal-to-mask ratio (SMR) calculation is given for subband coding of the WLP residuals of audio signals. The...
