Abstract: The present solution can provide content based stereo signal processing for an audio system, such as an audio system of a vehicle. An audio system can include one or more processors of a data processing system coupled with memory to identify a stereo signal of an audio system of a vehicle. The one or more processors can determine a factor indicative of correlation between a first portion of the stereo signal and a second portion of the stereo signal. The one or more processors can select, based on the factor, a setting for generating a plurality of audio signals. The audio system can include a decorrelation circuit to generate, based on the stereo signal and according to the setting, the plurality of audio signals for a plurality of speakers in the vehicle.

Abstract: Provided are an electronic system for adaptively adjusting allocation of a memory area and a method of operating the electronic system. The electronic system includes: a modem configured to perform data transmission; at least one IP block configured to execute an application; a boot data memory configured to store first boot data corresponding to the alternative mode and second boot data corresponding to a standard mode; a main memory including a first area allocated to the modem and a second area allocated to the at least one IP block, in the standard mode; and a processor configured to boot the main memory by using the first boot data or the second boot data based on an operation mode, wherein the processor is configured to re-allocate the first area to the at least one IP block by re-booting the main memory by using the first boot data in the alternative mode.

Abstract: An audio system for a vehicle is provided having a bass-range speaker mounted in a vehicle cavity. The speaker has a front side for producing an acoustic output in a passenger compartment of the vehicle. The vehicle cavity encloses a back side of the speaker. A duct having a first end is in fluid communication with the vehicle cavity and a second end is in fluid communication with the atmosphere outside the vehicle.

Abstract: Materials used in acoustic transducer membranes need very specific qualities that in any real system require many tradeoffs to be made. Graphene and graphene related materials are a newly discovered class of materials with some exceptional properties that offer the potential for significant contributions to the performance of many acoustical transduction systems. Accordingly the inventors have established graphene oxide based transducers as the basis of ribbon microphones and diaphragm loudspeakers using low cost manufacturing and processing techniques.
