如何在浏览器播放amr格式的音频文件

  • Post author:

良心建议：

网页不支持播放amr格式的音频文件，有条件的同学可以在后台使用ffmpeg转码后再在前端使用audio标签进行播放（MP3或wav），如果非要在网页播放amr，请继续阅读

本篇分两部分，播放本地的amr文件和播放在线的amr文件，一边看代码一边解释,原理都是把amr文件转换成base64字符串后直接播放该字符串

本地的amr文件（pc）：

html代码

<input type=”file” name=”” id=”upload” value=”” οnchange=”selectFile(this)”/>

js代码

<script src=”voice-2.0.js”></script>

<script src=”audio.min.js”></script>

// 初始化两个插件

audiojs.events.ready(function () {


var as = audiojs.createAll();

});

RongIMLib.RongIMVoice.init();

function selectFile(file) {


var reader = new FileReader() // 接收选择的amr文件

reader.readAsDataURL(file.files[0]) // 对amr文件进行转码

reader.onload = function (f) {


var base64Str = f.target.result.split(‘,’)[1]  // base64字符串，有兴趣的可以输出来看一看

RongIMLib.RongIMVoice.play(base64Str); // 直接播放该base64

字符串}

}

作用：选择amr文件后进行转码（base64），直接播放base64字符串

播放在线的amr文件：原理都是把amr文件转码成base64字符串后再直接播放该字符串

上代码（只有js）

<script src=”voice-2.0.js”></script>

<script src=”audio.min.js”></script>

// 初始化两个插件

audiojs.events.ready(function () {


var as = audiojs.createAll();

});

RongIMLib.RongIMVoice.init();

function get_voices() {


$.ajax({


url: ‘url’, // 请求后台，后台把amr文件进行base64编码后直接返回

dataType: ‘text’, // 注意：因为是返回base64字符串，所以要用‘text’类型

success: function (res) {


RongIMLib.RongIMVoice.play(res) // 同样道理，直接播放该base64字符串

},

error: function (res) {


console.log(res)

}

})

}

}

二。

将amr文件转化成base64字符串，用js转换成音频播放

js文件下载链接: https://pan.baidu.com/s/1kWsLOc3 密码: 2ca5

$a=file_get_contents(“./a.amr”);

$b=base64_encode($a);

// echo $b;

// die;

?>

<!DOCTYPE HTML>

<html>

<head>

<script src=”audio.min.js”></script>

</head>

<script src=”voice-2.0.js”></script>

<script>

audiojs.events.ready(function() {


var as = audiojs.createAll();

});

</script>

<body>

<input type=”button” value=”play” id=”playId”/>

<input type=”button” value=”stop” id=”stopId”/>

</body>

<script type=”text/javascript”>

RongIMLib.RongIMVoice.init();

document.getElementById(“playId”).onclick = function(){


RongIMLib.RongIMVoice.play(“<?php echo $b;?>”);

};

document.getElementById(“stopId”).onclick = function(){


RongIMLib.RongIMVoice.stop();

};

</script>

</html>

三，

这个需求由来已久，公司的语音订单很多，每次客服都是从服务器down下语音来听。很不方便。。于是我就上网扒拉看有么有什么web播放器能播放amr格式的音频文件，

amr百度百科

总之找了很久。，，然后发现苹果的QuickTime Player 播放器能播放。。

具体步骤如下：

1.下载

QuickTime Player

2.在服务器端需要添加web服务器的mime.type支持就是在Apache 啊nginx啊之类的mime.type文件增加如下

  1. audio/amr amr
  2. audio/amr-wb amr
  3. audio/amr-wb+ amr
  4. audio/amr amr amr

3.在页面插入如下代码


源码


复制


打印


关于

  1. <button class=”icon-audio” id=”playerBtn” style=”margin:0 5px;cursor:pointer;” playerurl=”http://xxx.com/abc.amr”>播放</button>
  2. <div style=”width:1px;height:1px;” id=”playerQT”>
  4. </div>
  5. //js代码如下。。好吧用到了jquery自己替换吧
  6. var playerQT = document.getElementById(“playerQT”);
  7. $(“#playerBtn”).bind(“click”,function(e){
  8. var playerUrl = e.target.getAttribute(“playerUrl”);
  9. playerAudio(playerUrl);
  10. });
  11. function playerAudio(url){
  12. var html = ‘ltembed width=”1px” height=”1px” name=”plugin” src=”‘+url+'” type=”audio/amr” id=”QT_EMB”>’;
  13. playerQT.innerHTML = html;
  14. }

4.在获取这个amr的url里服务端代码增加header如下

  1. header(’Content-type: audio/amr’);
