Title (EN) AUTO-MUTE AUDIO PROCESSING
(FR) TRAITEMENT AUDIO DE MISE EN SILENCE AUTOMATIQUE
Abstract:
(EN) An audio processing circuit may have a first path for processing multi-bit audio signals in parallel with a second path for processing single-bit audio signals. The parallel paths may share a common input node for receiving audio data and a common output node for reproducing audio at a transducer. Each path may have a volume control for adjusting an output of the path. The audio processing circuit may determine a type of an audio signal received at the input. The path not corresponding to the detected type of the audio signal is muted, and the path corresponding to the detected type of audio signal is unmuted.
(FR) Selon l'invention, un circuit de traitement audio peut disposer d'un premier trajet servant à traiter des signaux audio multi-bits en parallèle avec un second trajet servant à traiter des signaux audio à un seul bit. Les trajets parallèles peuvent partager un nœud d'entrée commun de façon à recevoir des données audio, et un nœud de sortie commun de façon à reproduire du son au niveau d'un transducteur. Chacun des trajets peut disposer d'une commande de volume afin de régler une sortie du trajet. Le circuit de traitement audio peut déterminer un type d'un signal audio reçu à l'entrée. Le trajet qui ne correspond pas au type détecté du signal audio est mis en mode sourdine, et le trajet qui correspond au type détecté de signal audio est sorti du mode silencieux.
