Claim:
1. A method for characterizing a multi-channel loudspeaker configuration, comprising: producing a first probe signal and a second pre-emphasized probe signal from a same frequency domain signal, producing the first probe signal further comprising: supplying the first probe signal to a plurality of audio outputs coupled to respective electro-acoustic transducers positioned in a multi-channel configuration in a listening environment for converting the first probe signal to a first acoustic response and for sequentially transmitting the acoustic responses in non-overlapping time slots separated by silent periods as sound waves into the listening environment; and for each said audio output, based on the delays to each said acousto-electro transducer, determining a distance and at least a first angle to each said electro-acousto transducer; and using the distances and at least said first angles to the electro-acousto transducers, automatically selecting a particular multi-channel configuration and computing a position for each electro-acousto transducer in that multi-channel configuration within the listening environment.
