摘要: | We propose a new technique for common-acoustic-poles and zeros (CAPZ) modeling. In 3-D sound processing, head-related transfer functions (HRTF's) record channels' characteristics from different locations to both ears. Compared to conventional pole/zero models, it is more efficient to model HRTF's by using CAPZ modeling. Based on balanced model truncation (BMT), jointly BMT is proposed to effectively model a group of HRTF's using common-poles IIR filters. The simulation result shows the proposed method is superior to the previous Prony and Shanks methods. |
