基于HTML5的Web Audio技术实现手机版简易钢琴

The Reality of Mobile Simple Virtual Piano Using Web Audio Based on HTML5

现代信息化技术的快速发展,使得能够以软件的形式实现虚拟化的乐器,比如钢琴等。以前实现的虚拟化钢琴常使用按键触发加载音频文件方式发声,由于音频文件大小和内存加载耗时等操作,这种设计在按琴键时有时会感受到明显延时。随着HTML5中Web Audio技术的不断完善,本文使用该技术,结合JS设计出的虚拟简易钢琴有很好的音效和灵敏度,同时在职业院校软件专业Web前端开发课程的实践中取得了良好教学效果。

With the rapid development of modern information technology,virtual instruments such as piano can be realized in the form of software.Previously,the virtual piano often uses the key trigger to load audio file to make sound.Due to operations such as audio file size and memory load time,this design would sometimes experience significant delay when pressing the keys.With the continuous improvement of Web Audio technology in HTML5,this paper uses this technology,combined with JS to design a virtual simple piano with good sound effect and sensitivity,and has achieved good teaching effect in the practice of Web front-end development course of software specialty in vocational colleges.
