Claim:
1. An apparatus for determining a position of a microphone, the apparatus comprising: a multi-channel signal receiver for receiving a multichannel signal comprising at least a first channel for rendering by a first speaker at a first position and a second channel for rendering by a second speaker at a second position; a first signal generator for generating a first correlated signal from the multichannel signal, the first correlated signal comprising correlated signal components for the first channel and the second channel; a second signal generator for generating a first uncorrelated signal from the multichannel signal, the first uncorrelated signal comprising signal components of the first channel not correlated with signal components of the second channel; a microphone signal receiver for receiving a microphone signal from the microphone a first correlator for determining a first correlation signal from a correlation of the microphone signal and the first correlated signal; a second correlator for determining a second correlation signal from a correlation of the microphone signal and the first uncorrelated signal; and a position estimator for estimating the position of the microphone in response to the first correlation signal and the second correlation signal.
