ABSTRACT:
An automotive audio controller is provided for receiving an audio signal from an audio source and providing a filtered audio signal that may help compensate for ambient noise in the automobile. The audio controller may have a vibration sensor that generates a vibration signal indicative of vibrations in the automobile. A dynamic filter of the audio controller may receive the vibration signal and the audio signal, and change the gain level and/or tone of the audio signal based on the vibration signal to generate the filtered audio signal. The audio controller also may receive a speed signal, and change the gain level and/or tone of the audio signal based on the speed signal to generate the filtered audio signal.
