在使用JavaScript的base64播放.wav声音文件连接codeD [英] play .wav sound file encoded in base64 with javascript

问题描述

我能够通过以下使用JavaScript播放声音，

Am able to play sound with javascript through the following,

    var snd = new Audio('sound.wav');
    snd.play();

本播放所需的声音，但有时加载缓慢或可能甚至不加载所有
所以我带$ C $光盘基地64的声音，并试图通过这种方式进行播放。

This plays the required sound but sometimes it loads slowly or might not even load at all so i encoded the sound in base 64 and tried to play it this way.

      var splash = {
prefix: "data:audio/wav;base64,",
sound: [ "*base64 string here*" ] };

    var snd = new Audio(splash); 
    snd.play();

但声音不玩了，有没有变通的办法？

but the sound does not play, is there a way around it ?

推荐答案

这看起来并不像正确的方式使用的音频的构造函数<一个href=\"https://developer.mozilla.org/en-US/docs/Web/API/HTMLAudioElement\">HTMLAudioElement / <一个href=\"https://developer.mozilla.org/en-US/docs/Web/HTML/Element/audio\"><$c$c><audio>.

That doesn't look like the correct way to use the Audio constructor for HTMLAudioElement / <audio>.

轻微的调整

var snd = new Audio("data:audio/wav;base64," + base64string);
snd.play();

如果它工作在控制台，但不是在脚本中，它可能会越来越垃圾回收，在这种情况下，范围它，所以它会留

If it works in console but not in script, it may be getting garbage collected, in which case scope it so it will stay

var Sound = (function () {
    var df = document.createDocumentFragment();
    return function Sound(src) {
        var snd = new Audio(src);
        df.appendChild(snd); // keep in fragment until finished playing
        snd.addEventListener('ended', function () {df.removeChild(snd);});
        snd.play();
        return snd;
    }
}());
// then do it
var snd = Sound("data:audio/wav;base64," + base64string);
