(EN) AUDIO STREAM MIXING SYSTEM AND METHOD
(FR) SYSTÈME ET PROCÉDÉ DE MÉLANGE DE FLUX AUDIO
Abstract
(EN)
Provided are a system and method of mixing a second audio stream with a first audio stream in an audio output device. The system is configured to execute the method, comprising buffering and outputting the first audio stream via the audio output device as unmodified output, determining at least one insertion spot within the first audio stream, modifying the first audio stream at an insertion spot to avoid content loss, outputting the second audio stream at the insertion spot, and resuming unmodified output of the first audio stream at or near a completion of the second audio stream. Modifying the first audio stream can include pausing and/or warping the first audio stream at the insertion spot. The audio output device can be a vehicle head unit or a wireless device, such as a mobile phone.

L'invention concerne un système et un procédé de mélange d'un second flux audio avec un premier flux audio dans un dispositif de sortie audio. Le système est conçu pour exécuter le procédé, consistant à mettre en mémoire tampon et à sortir le premier flux audio par l'intermédiaire du dispositif de sortie audio en tant que sortie non modifiée, déterminer au moins un point d'insertion dans le premier flux audio, modifier le premier flux audio au niveau d'un point d'insertion afin d'éviter une perte de contenu, émettre le second flux audio au niveau du point d'insertion et reprendre la sortie non modifiée du premier flux audio au niveau ou à proximité d'une complétion du second flux audio. La modification du premier flux audio peut comprendre la mise en pause et/ou la déformation du premier flux audio au niveau du point d'insertion. Le dispositif de sortie audio peut être une unité de tête de véhicule ou un dispositif sans fil, tel qu'un téléphone mobile.
