HTML5环形音乐播放器

通过 HTML5,音乐在网络上东山再起。添加音频文件就像插入图像那样简单,并且用户能在浏览器外播放音乐,从而实现惊人的音乐体验。<audio> 标签的推出使您不再需要外部音乐播放器,在网站上实现真正的声音融合。 随着 HTML5 的出现,发生了一些重大变化,特别是在音乐和音频方面。开发人员不再要求 web 冲浪者使用 Adobe Flash、Apple QuickTime 或 Microsoft Windows 媒体播放器等特殊的播放器。这意味着用户不必担心是否有最新的兼容插件(或任何播放器插件)。他们只需打开自己喜欢的浏览器并聆听能发出声音的任何内容,如音乐、有声读物、FX 声音效果或朋友和家人录制的消息。

好吧,直接看代码:
