摘要： A method of virtually tuning an audio system that incorporates an acoustic compensation system, where the audio system is adapted to play audio signals in a listening environment over one or more sound transducers. The acoustic compensation system has an audio sensor located at a sensor location in the listening environment. The transfer functions from each sound transducer to the audio sensor location are inherent. The method contemplates recording noise at the sensor location, and creating virtual transfer functions from each sound transducer to the sensor location based on the inherent transfer functions from each sound transducer to the sensor location. Audio signals are processed through the virtual sound transducer to sensor location transfer functions. A virtual sensor signal is created by combining the audio signals processed through the virtual sound transducer to sensor location transfer functions with the noise recorded at the sensor location.

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.
