js中的隨機聲音

Question

如何在JavaScript中創建隨機聲音並將其保存到桌面？

Answer 1

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

「riffwave.js」是音頻數據編碼到可以用來播放合成聲音與格式（PCM一個RIFF容器內）一個微小的JavaScript庫HTML5音頻元素。

例如隨機聲音的產生

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)
