A method, and the apparatus for its implementation, for encoding an input signal includes the steps of transforming an input signal into frequency components, as for example by spectrum transform processing, separating the frequency components into a first signal consisting of tone characteristic components and a second signal consisting of other components, encoding the first signal, and encoding a signal based on the second signal.
Ce procédé comprend les étapes de conversion de signaux acoustiques d'entrée en une composante de fréquence; de séparation de la sortie des moyens de conversion en une composante de tonalité et en une autre composante (composante bruit); codage de la composante tonalité; codage de la composante bruit; et génération de la séquence de codage à partir de la sortie obtenue à l'étape de codage.
