| Abstract(in English) | We propose a dedicated test signal for acoustic measurement specifically for room acoustics based on our recent method. The method uses periodic nature of the discrete Fourier transform for implementing a simultaneous measurement of multiple acoustic attributes based on an extended time-stretched pulse using cascaded all-pass filters. We developed an interactive and real-time tool based on the proposed implementation and open-sourced in our GitHub repository. |
