Abstract

Module (402) de codage binaire d'une enveloppe d'un signal, comprenant un module (502) de codage d'un premier mode à longueur variable. Selon l'invention, le module de codage d'un premier mode intègre un détecteur de saturation d'enveloppe et ledit module (402) de codage comprend également un deuxième module (503) de codage d'un second mode, disposé en parallèle au module (502) de codage du premier mode, et un sélecteur (504) de mode apte à retenir un des deux modes de codage, en fonction d'un critère de longueur de code et du résultat issu du détecteur de saturation d'enveloppe. Application au codage par transformée de signaux audio-fréquences.
