Claim:
1. A computer-implemented method of adjusting signals in an automobile audio system having at least two near-field speakers located close to an intended position of a listener's head in a vehicle cabin of an automobile and at least a first fixed speaker and a second fixed speaker positioned near a left corner and a right corner, respectively, of the vehicle cabin forward of the intended position of the listener's head, the computer-implemented method comprising: processing a source audio signal having at least two channels, including: if the content is identified as being of the first type, defining a first soundstage including applying a first set of weights to the component channel signals for each of a set of designated positions other than the actual locations of the speakers, otherwise, defining a second soundstage including applying a second set of weights to the component channel signals for each of the set of designated positions; receiving user input to effect a transition to a user-desired soundstage between the first soundstage and the second soundstage; combining the first set of weights and the second set of weights to generate a combined set of weights, the relative contribution of the first set of weights and the second set of weights in the combined set of weights being based on a value of the user input; and defining the user-desired soundstage including applying the combined set of weights to the component channel signals at each of the set of designated positions.
