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.
