| Abstract: | ITD (Interaural Time Difference) estimation is an important part of the auditory signal process such as sound source localization. CPSP (Cross-power spectrum phase) is a popular ITD estimation method but requires FFT and IFFT that are involved with much computation. To reduce the amount of computation of CPSP, we propose an approximation method of CPSP using zero-crossing process and call it CPSP-ZC. The CPSP-ZC is structurally based on ZCTD which is a computationally efficient ITD estimation method using zero-crossing process. We believe that CPSP-ZC will be a good alternative of CPSP when only little computation is allowed. |
