Title (EN) ENTERTAINMENT AUDIO PROCESSING
(FR) TRAITEMENT AUDIO DE DIVERTISSEMENT
Abstract: front page image
(EN)An entertainment audio processing system includes a music limiter configured to receive an audio signal, volume control information for music, and volume control information for announcement. The music limiter is further configured to calculate a gain parameter based on a music-to-announcement ratio. In another aspect, an entertainment audio processing system includes a mixer configured to substantially match a left audio signal channel and a right audio signal channel. The entertainment audio processing system further includes an equalizer configured to introduce magnitude and phase changes between the left audio signal channel and the right audio signal channel.
(FR)Cette invention concerne un système de traitement audio de divertissement comprenant un limiteur de musique configuré pour recevoir un signal audio, des informations de commande de volume pour musique, et des informations de commande de volume pour annonce. Le limiteur de musique est en outre configuré pour calculer un paramètre de gain sur la base d'un rapport musique à annonce. Selon un autre aspect, un système de traitement audio de divertissement comprend un mélangeur configuré pour faire sensiblement correspondre un canal de signal audio gauche et un canal de signal audio droit. Le système de traitement audio de divertissement comprend en outre un égaliseur configuré pour introduire des variations d'amplitude et de phase entre le canal de signal audio gauche et le canal de signal audio droit.
