Effective Car Audio System Enabling Individual Signal Processing Operations of Coincident Multiple Audio Sources through Single Digital Audio Interface Line

Document Thumbnail

There are three major audio sources in recent car environments: Primary audio (usually music including radio), Navigation voice prompt and Hands-free voice. Listening situations in cars include not only listening single audio source, but also listening concurrent multiple audio sources – for example, navigation guided as listening music and navigation guided or listening music as talking on a hands-free cell phone. In this paper, firstly, a conventional external amplifier system connected with a head unit by three audio interface lines was introduced. Then, effective automotive audio system having single SPDIF interface line which is capable of concurrent processing of above three kinds of audio sources was proposed. New system leads to reduce wire harness in car environments and also increases voice qualities by transmitting voice signals via an SPDIF digital line compared with that via analog lines.
