Abstract
Several windows are designed following an optimization procedure, with the target application being for linear prediction (LP) analysis within the ETSI adaptive multi-rate (AMR) coder. The goal is to explore the possibility of reducing the lengths of the windows so as to decrease computation. In addition, several windows are designed that are placed at different shifted positions with respect to the original with the objective of lowering the coding delay. It is shown that the alternative windows produce a similar perceptual quality with respect to the original, with the added benefits of reduced computational cost and lowered coding delay.
