In general, frequency domain based techniques are preferred to time domain techniques for the implementation of audio crosstalk cancellation due to time domain techniques suffer from more computations. In this paper, the computational difficulty of real FFT on DSP processors is analyzed and to overcome the disadvantages, two optimization methods (Parallel Filtering and Mixed Filtering) are proposed for the implementation of Audio Crosstalk cancellation. These methods are developed based on fast convolution using overlap save method & Finding DFTs of two real sequences using single Complex DFT.
