Android音樂同步播放系統之研究

本研究是利用Android系統來開發一個音樂同步播放的應用程式。當一群人聚在一起想聽同一首歌曲的時候，雖然沒有外接喇叭等擴音設備，也可以利用這款應用程式把所有人的手機連接起來，形成一個「環繞的巨型喇叭」，多台Android設備適當地放在不同地方的話，更可以塑造出環繞立體聲的效果。本研究開發的系統，使用websocket做為各設備之間同步訊息的傳送機制，不僅可以讓多台手機、平板同步播放音樂，同時也支援歌詞同步的功能。我們希望透過這樣的系統，可以更方便人們一同享受音樂的樂趣。

In this research, we build a music synchronous application for an Android system. When a group of people get together and want to listen to the same music without external speakers or other audio equipment, the proposed system can connect all the people’s smart phones into a “surrounded giant speakers”. If we adequately put the Android devices in different places, we may also create a surrounded sound effect. The system uses the websocket to synchronize the messages between devices, and supports not only for music synchronization, but also the lyrics synchronization between devices. We hope that such a system can help people to share and enjoy the fun of music.
