Low Frequency Crosstalk Cancellation and Its Relationship to Amplitude Panning
Eric Carlos Hamdan, Filippo Maria Fazi
Abstract
The low frequency behaviour of the source strength solution of the two loudspeaker crosstalk cancellation system is analysed. Using the rigid sphere head model, an accurate 1 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">st</sup> order approximation of the source strength solution is derived, assuming a centred listener position. It is shown that the 1 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">st</sup> order approximation of the source strength solution corresponds to the well-known stereo sine law. The validity of this approximation for real systems is supported by a comparison of simulated low frequency complex source strengths and the real stereo panning functions. To obtain a realistic analysis, the simulated source strengths are created using KEMAR head-related transfer functions. It is shown that the simulated source strengths converge to the stereo sine law in the low frequency limit under the expected conditions.
