Warped or Laguerre-based linear prediction can be utilized in audio coding in such a way that it accounts for the spectral masking effects. This requires running a psycho-acoustic model to calculate the masking curve; and then the corresponding prediction parameters are derived from the masking curve. As an alternative, we propose to bias the linear prediction solution in a perceptually relevant way...
Linear prediction (LP) is a widely used technique in single-channel speech coding. LP can also be applied to stereo (or multi-channel) audio coding, but it requires a scheme for quantization and efficient transmission of stereo-LP parameters. We propose to transmit the (forward) normalized reflection matrices together with the zero-lag correlation matrix. Furthermore, we select a parameterization...
