An integrated wireless audio unit (WAU) for a vehicle audio system is disclosed herein, that can take a plurality of audio streams as input, and output the audio streams to a plurality of output devices, where the output transmission is low latency (e.g., less than 15 ms end-to-end) and time-synchronous (e.g., with no float or drift in latency). The input streams may be received via various protocols in the digital or analog domain, and the WAU may mix, blend, and process the input streams to generate the output streams, and broadcast the output streams to audio devices within the vehicle. The WAU may employ various strategies for synchronizing different types of audio streams, based on relevant factors. As a result, audio playback at the vehicle may be performed with tighter integration with vehicle speakers and tactile transducers, and a flexibility in routing the audio streams may be increased.

Disclosed herein is an integrated wireless audio unit (WAU) for an in-vehicle audio system that may take multiple audio streams as inputs and output the audio streams to multiple output devices, where the output transmissions have low latency (e.g., end-to-end less than 15 ms) and are time synchronized (e.g., the latency does not float or drift). The input streams may be received via various protocols in the digital or analog domain, and the WAU may mix, fuse, and process the input streams to generate an output stream, and broadcast the output stream to an audio device within the vehicle. The WAU may employ various policies to synchronize different types of audio streams based on correlation factors. Accordingly, audio playback at the vehicle may be performed through closer integration with the vehicle speaker and the haptic transducer, and flexibility of routing the audio stream may be improved.
