Title (EN) NOISE GENERATION IN AUDIO CODECS
(FR) GÉNÉRATION DE BRUIT DANS DES CODECS AUDIO
Abstract: front page image
(EN)The spectral domain is efficiently used in order to parameterize the background noise thereby yielding a background noise synthesis which is more realistic and thus leads to a more transparent active to inactive phase switching.
(FR)Le domaine spectral est utilisé efficacement pour paramétrer le bruit de fond, produisant ainsi une synthèse du bruit de fond qui est plus réaliste et qui conduit à un passage plus transparent d'une phase active à une phase inactive.
