(FR) CIRCUITS AUDIO COMMUTABLES POUR TERMINAUX MOBILES, PROCEDES ET PRODUITS DE PROGRAMME INFORMATIQUE PERMETTANT DE FAIRE FONCTIONNER LESDITS CIRCUITS AUDIO
Abstract:
(EN) Audio circuits for a mobile terminal include a microphone and an audio signal processing circuit having an input coupled to the microphone. The audio signal processing circuit has a switchable portion and is configured to switch between a voice mode utilizing the switchable portion and a full fidelity mode not utilizing the switchable portion responsive to a mode signal coupled thereto.
(FR) L'invention concerne des circuits audio destinés à un terminal mobile comprenant un microphone et un circuit de traitement de signal audio possédant une entrée couplée au microphone. Le circuit de traitement de signal audio comprend une partie commutable et est configuré afin de passer d'un mode vocal utilisant la partie commutable à un mode fidélité totale n'utilisant pas la partie commutable sensible à un signal de mode couplé à ladite partie.
