| Outline of Final Research Achievements |
Microphone array signal processing is an important technique to estimate the direction of arrival of sound or to enhance a target sound in noisy environment by processing multi-channel signals. In the microphone array signal processing, a tiny time difference between channels is important information. Therefore, multi-channel signals have to be recorded in a synchronized way in conventional framework. While in this study, we have developed a technique to synchronize recording signals or to estimate microphone positions without any a priori knowledge in order to use asynchronous individual recording devices such as smartphones, laptop PC, and IC recorder.
