摘要： An automobile audio system having at least two near-field speakers located close to an intended position of a listener's head is configured by determining a first binaural filter that causes sound produced by each of the near-field speakers to have characteristics at the intended position of the listener's head of sound produced by a sound source located at a first designated position other than the actual locations of the near-field speakers, determining an up-mixing rule to generate at least three component channel signals from an input audio signal having at least two channels, and configuring the audio system to, determine a first binaural signal corresponding to a combination of the component channel signals originating at the first designated position, and filter the first binaural signal using the first binaural filter and to output the filtered signals using the near-field speakers.

摘要： Signals in an automobile audio system having at least two near-field speakers located close to an intended position of a listener's head are adjusted such that in a first mode, audio signals are distributed to the near-field speakers according to a first filter that causes the listener to perceive a wide soundstage, and in a second mode, the audio signals are distributed to the near-field speakers according to a second filter that causes the listener to perceive a narrow soundstage. A user input of a variable value is received and, in response, distribution of the audio signals is transitioned from the first mode to the second mode, the extent of the transition being variable based on the value of the user input.

摘要： An automobile audio system includes a signal processor configured to receive and process audio signals from a source and provide processed audio signals to an amplifier, a first headrest including a headrest speaker and coupled to a driver's seat, a first fixed speaker positioned near a left corner of the vehicle's cabin forward of the headrest, a second fixed speaker positioned near a right corner of the vehicle's cabin forward of the headrest, and a headrest accessory port located in a passenger's seat. The port is configured to connect the audio system to a second headrest speaker. The processor uses a first set of parameters for processing the received audio signals when the first headrest speaker is connected and the second headrest speaker is not connected, and a second set of parameters for processing the received audio signals when both the first and second headrest speaker are connected.
