Audio encoder low delay signals employing analysis by synthesis techniques.

摘要

The coding system AUDIO SIGNALS LOW-DELAY, which uses analysis techniques SYNTHESIS, comprised of elements (AFC, AFD) to adapt the spectral parameters and the order of prediction synthesis filters (SYC, SYD) CODER (CDA, CDB) and decoder (DA, DB) and filters perceptual weighting (FP) ENCODER IN EACH PICTURE, starting with the reconstructed signal RELATED previous image. IN THE CASE OF A CELP coder, you also need ELEMENTS (AGC, AGD) TO ADAPT, starting with the reconstructed signal, a factor LINKED TO ENERGY MEDIA SIGNAL INPUT, EARNING THROUGH WHICH weighted VECTORS INNOVACION .
