An audio system includes a level controller receiving an input audio signal from an audio medium. The level controller includes a gain adjust module producing an output audio signal based on the input audio signal. A filter arrangement is communicatively coupled to the level controller. The filter arrangement receives the output audio signal and divides the output signal into a plurality of filtered signals. Each of the filtered signals corresponds to a respective frequency band. A multiband dynamics controller is communicatively coupled to the filter arrangement. The multiband dynamics controller receives the filtered signals and applies a respective gain characteristic to each of the filtered signals to thereby produce a plurality of gain adjust signals. The gain adjust signals are combined into a multiband dynamics controller output signal.

Audio system including multiband audio dynamics processor

Exemplary embodiments of the present invention relate to a power line communication (PLC) system. For example, the PLC system may include a PLC server configured to provide electrical power and electronic communications through a PLC bus to a number of electronic devices, such as an instrument cluster, infotainment interface, rear-seat entertainment console, aftermarket accessories, and the like. The PLC system may also include a power system that may be coupled to an electrical grid for charging a battery associated with one or more of the electronic devices. The power system may be communicatively coupled to the PLC bus, enabling the devices coupled to the PLC bus to communicate with a service provider through the electrical grid. The communications between the devices coupled to the PLC bus and remote devices coupled through the electrical grid may be conducted using a common communication protocol.

Power line communication system and method

Apparatus and method of operating an audio system

An audio system includes an automatic level controller receiving at least one input audio signal from at least one audio medium. The automatic level controller includes a gain adjust module for producing an output audio signal based on the at least one input audio signal. A difference between a maximum sound level and a minimum sound level of the at least one input audio signal is greater than a difference between a maximum sound level and a minimum sound level of the output audio signal. A filter arrangement is communicatively coupled to the automatic level controller. The filter arrangement receives the output audio signal and divides the output signal into a plurality of filtered signals. Each of the filtered signals corresponds to a respective frequency band. A multiband dynamics controller is communicatively coupled to the filter arrangement. The multiband dynamics controller receives the filtered signals and applies a different respective gain characteristic to each of the filtered signals to thereby produce a plurality of gain adjust signals. The gain adjust signals are combined into a multiband dynamics controller output signal.

Multiband audio dynamics processor

A vehicle audio/video media system includes an adapter apparatus in electrical communication with an audio/video head unit. The adapter apparatus includes a digital input receiving digital audio/video content from an external source. A digital-to-analog converter is coupled to the digital input and converts the digital audio/video content into analog audio/video content. An output device is coupled to the digital-to-analog converter. The output device transmits the analog audio/video content to the audio/video head unit.

In-vehicle interface

The interface uses a combination of controls that retain essentially the same function throughout all modes and features and controls that vary based on the active mode or feature. The interface also includes a display. The display can provide text information, graphic information or a combination of text and graphics. The arrangement of the mode controls, the soft controls and the display is designed to facilitate the user's interaction with the system. The system provides some redundant controls so that the user can select the control that is most convenient or intuitive for that user.
