N2 - We have implemented a high-definition 3D audiovisual reproduction system based on higher-order ambisonics (HOA) using a surrounding-157-loudspeaker array combined with a 3D projection display to reproduce information with high senseof-presence. In this report, we introduce the system overview as well as an investigation to realize good system synchronization, which we are keenly devoted to. Results of the investigation show that all 157 channels of loudspeakers were completely synchronized within the one-sample level (48 kHz) controlled using a single PC with three Multichannel Audio Digital Interface (MADI) systems. Moreover, the latency among 157 audio signals and the video signal was only about 1.1 ms.
