Abstract
An apparatus comprises a receiver () receiving a multichannel signal comprising two channels for rendering by a first speaker () at a first position and a second speaker () at a second position respectively. A first signal generator () generates a correlated signal and a second signal generator () generates an uncorrelated signal from the multichannel signal, the signals comprising respectively correlated and uncorrelated signal components for the channels. A receiver () receives a microphone signal from the microphone (). A first correlator () determines a first correlation signal from a correlation of the microphone signal and the correlated signal, and a second correlator () determines a second correlation signal from a correlation of the microphone signal and the uncorrelated signal. A position estimator () estimates a position of the microphone from the first and second correlation signals. For example, timings of peaks in the correlations signals may be used to determine propagation delays and thus distances from the speakers ().
