交錯音訊消除系統就是利用頭部相關轉移函數的特性來預測用揚聲器播放3-D音訊時將會產生的交錯音訊，並事先將之消除以使聽者能使用揚聲器感知3-D音訊。由於交錯音訊消除系統的作用範圍非常的小，所以通常會利用頭部追蹤系統使作用範圍能保持在聽者頭部。而為了能夠跟上移動中的目標，交錯音訊消除系統必須能夠快速的實現。這篇論文使用了直接逼近濾波器頻譜特性的濾波器設計方法來實現用在交錯音訊消除系統的濾波器。和傳統的適應性濾波器設計法相比，它能避免傳統的適應性濾波器設計法所必需的收歛時間。我們並且修改濾波器設計法讓它更適合同在設計交錯音訊消除系統上。實驗結果顯示在消除交錯音訊的能力上，它能提供比適應性濾波器設計法和修改前的設計法更好的效果。

Crosstalk cancellation system is utilized the characteristic of head-relative transfer function (HRTF) to predict the crosstalk signal that introduced when play 3-D audio using pair of loudspeakers, and eliminate it in prior, then the listener can perceive 3-D audio by loudspeakers. Because the equalization zone of crosstalk cancellation system is very tiny, thus it usually utilize head-tracker system to keep the equalization zone is always on the listener’s head. And for keep up with moving target, the crosstalk cancellation system should be fast implemented. In this thesis, we examine a method to implement the crosstalk cancellation system that directly approaches the characteristic of the filter in frequency domain. Compare with the traditional adaptive filter design method, it can avoid converge time. Furthermore, we modify the design method to make it more suitable for designing crosstalk cancellation system. Experiment result shows in eliminate crosstalk signal, it can provide better performance than the adaptive filter design method and un-modified method.
