js中的随机声音

Question

如何在JavaScript中创建随机声音并将其保存到桌面？

Answer 1

使用像Riffwave库：http://codebase.es/riffwave/

“riffwave.js”是音频数据编码到可以用来播放合成声音与格式（PCM一个RIFF容器内）一个微小的JavaScript库HTML5音频元素。

例如随机声音的产生

var data = []; 

for (var i=0; i<1000; i++) { 
    // fill data with random samples 
    data[i] = Math.round(255 * Math.random()); 
} 

var wave = new RIFFWAVE(data); // create the wave file 

/* 
    pass wave.dataURI property to a server page via POST and 
    then re-send the content along with the right headers 
    for a wav file so to enforce download 

    or just redirect your client using data:uri schema, like 
    location.href = wave.dataURI 
    (but this won't force the download in every browser)
