To conduct accurately controlled experiments using the local-lag concept in this remote ensemble task, we develop in the present study a new acoustic server system for supporting remote ensembles, which has a function of time stamp synchronization among remote servers and also has a function of setting a time stamp that is common to the recorded data files at remote sites. Through an elaborative measurement experiment, we demonstrate that the developed server can be a reliable platform for remote ensemble experiments.}, title = {ローカル・ラグ制御機能とログ同期機能を持つ音響サーバの開発}, year = {2012} }
