A Spatially Robust Least Squares Crosstalk Canceller

Crosstalk cancellation is a well-known technique to generate virtual 3D sound via loudspeakers. Usually, headphones are used to playback audio material, which has been ltered with HRTFs. Audio playback in a reverberant room using loudspeakers and crosstalk cancellation is our intended application. This raises the need for a robust design, since listeners might slightly move their heads during a listening session. The novel design is based on a known least squares crosstalk canceller design technique, but with added robustness. The robustness is achieved with the help of assumed stochastic perturbation systems, which lie in parallel to the actual propagation impulse responses, during the design process.
