The Whys and Wherefores of Microphone Array Crosstalk in Multichannel Microphone Array Design

The difference in the effect of cross-talk between coincident (or near-coincident) and spaced multichannel array systems – the cross-talk introduced by adjacent microphones to a specific segment – the cross-talk introduced by microphones on the opposing sides of an array – the effect of cross-talk in the transitory and quasi-steady state regions of a natural signal – crosstalk reduction in the quasi steady state region - image folding into “empty” areas. Each of these aspects of crosstalk has a different and definable influence on a specific segment of the multichannel microphone array system. Microphone arrays must therefore be designed to minimise their effect on the final front coverage or surround sound multichannel image.
