Abstract: A method of approximating a standardized studio experience when rendering surround sound signals in a vehicle having non-standard speaker locations comprises: receiving, by an audio system of a vehicle, surround-sound signals that also include a height dimension, the surround sound signals including first channels configured according to standardized speaker locations, wherein speaker positions of the audio system do not correspond to the standardized speaker locations; performing, using the audio system, sum and difference signal processing on respective pairs of the channels around the vehicle, the sum and difference signal processing based on the speaker positions of the audio system; and rendering, using the audio system, audio in the speakers of the vehicle based on the sum and difference signal processing of the surround-sound signals.

Abstract: A method of performing multiband bass management in a vehicle comprises: separating, by an audio system in a vehicle. first bass audio information from an audio signal. the first bass audio information comprising all contents of the audio signal below a first frequency: providing second bass audio information to each of multiple woofers of the audio system of the vehicle. the second bass audio information comprising all contents of the first bass audio information above a second frequency: and providing third bass audio information to fewer than all of the multiple woofers. the third bass audio information comprising all contents of the first bass audio information other than the second bass audio information.

Abstract: A vehicle includes a plurality of loudspeakers, memory storing pre-stored sound files, encoding a sound for rendering by the loudspeakers, memory storing an attribute file containing attributes associated with the sounds and associated with audio streams, the attributes defining parameters for rendering each of the sounds and audio streams. An audio manager is configured for receiving the pre-stored sound files, audio streams, and attributes from the attribute file, the received attributes corresponding to the received pre-stored sound files and audio files. The audio manager is configured for, based on the received attributes, determining relative priorities for rendering the received pre-stored sound files and audio streams. An audio mixer is configured for, based on the determined relative priorities, outputting signals to the loudspeakers to render the received pre-stored sound files and audio streams according to the determined relative priorities.

Abstract: A method of generating a multidimensional audio notification in a vehicle comprises: registering, in a vehicle having an audio system with multiple channels, an event for which a directional notification is to be generated; obtaining, from among multiple pre-rendered multidimensional sounds in a storage, a first pre-rendered multidimensional sound that is assigned to the event, the first pre-rendered multidimensional sound including audio for more than one of the multiple channels; and playing the obtained first pre-rendered multidimensional sound using the audio system.
