Abstract

A perceptually biased linear prediction scheme is proposed for audio coding. Using only simple modifications of the coefficients defining the normal equations for a least-squares error, the spectral masking effects are mimicked in the prediction synthesis filter without using an explicit psychoacoustic model. The main advantage of such a scheme is reduced computational complexity. The proposed approach was implemented in a Laguerre-based linear prediction scheme, and its performance was evaluated in comparison with a Laguerrebased linear prediction approach controlled by the ISO MPEG-1 Layer I–II model, as well as with one of the latest spectral integration–based psychoacoustic models. Listening tests clearly demonstrate the viability of the proposed method.
