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这样的库：http://codebase.es/riffwave/

  

“riffwave.js”是一个小型的JavaScript库，它将音频数据编码为格式（RIFF容器内的PCM），可用于播放HTML5音频元素的合成声音。

e.g。随机声音生成

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)
