Abstract
Method and apparatus are disclosed for determining and accounting for distortions to an audio signal due to the geometric properties of the interior cabin of a vehicle. An example vehicle includes a microphone, a seat having a plurality of seat positions, and a processor. The processor is configured to determine a first seat position corresponding to a point in time at which an audio signal is received, determine a cabin impulse response corresponding to the first seat position, and determine a filtered audio signal based on the cabin impulse response and the audio signal.
