我希望录制一些音频，然后才能播放它 . 能够customize the record interface对我来说很重要 .

在录制后的下面示例中，我得到-1的持续时间并且没有播放音频 .

Step 1. 已添加Media Plugin

cordova plugin add org.apache.cordova.media

Step 2. 我的代码

注意src是文档中请求的“amr” .

Android设备以自适应多速率格式录制音频 . 指定的文件应以.amr扩展名结尾 .

但是，我的文件结构中不存在“myrecording.amr”，因为我希望它会被创建 .

Javascript

var data = {
  rec: ""
};
$scope.record = function(){
    console.log('record');
    var src = "myrecording.amr";
    data.rec = new Media(src,
    function() {
      console.log("recordAudio():Audio Success");
    },

    function(err) {
      console.log("recordAudio():Audio Error: "+ err.code);
    });

    data.rec.startRecord();
}

$scope.stopRecording = function(){
    console.log('stop');
    data.rec.stopRecord();
}

$scope.playRecording = function(){
    console.log('play');
    data.rec.play();
}

$scope.logDuration = function(){
    console.log(data.rec.getDuration());
}

HTML

<button ng-click="record()">Record</button>
<button ng-click="stopRecording()">Stop Record</button>
<button ng-click="playRecording()">Play Record</button>
<button ng-click="logDuration()">Log Duration</button>

Output From Above

点击播放时没有播放音频 .

0     999846   log      record
1     001845   log      stop
2     002000   log      recordAudio():Audio Success
3     004657   log      play
4     008989   log      -1

任何帮助将不胜感激 . 如果我能回答任何问题，请告诉我 .

以下是我的工作步骤 .

1.运行这些命令

ionic start RecordTest blank
ionic platform add ios
cordova plugin add org.apache.cordova.media

2.创建RecordTest / www / myrecording.wav

3.将以下代码粘贴到RecordTest / www / index.html中

<!DOCTYPE html>

    <meta charset="utf-8">
    <meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width">

    // Wait for PhoneGap to load

    document.addEventListener("deviceready", onDeviceReady, false);

    // Record audio
    // 
    function recordAudio() {
        var src = "myrecording.wav";
        var mediaRec = new Media(src, onSuccess, onError);

        // Record audio
        mediaRec.startRecord();

        // Stop recording after 10 sec
        var recTime = 0;
        var recInterval = setInterval(function() {
            recTime = recTime + 1;
            setAudioPosition(recTime + " sec");
            if (recTime >= 3) {
                clearInterval(recInterval);
                mediaRec.stopRecord();
                mediaRec.play();
            }
        }, 1000);
    }

    // PhoneGap is ready
    //
    function onDeviceReady() {
        recordAudio();
    }

    // onSuccess Callback
    //
    function onSuccess() {
        console.log("recordAudio():Audio Success");
    }

    // onError Callback 
    //
    function onError(error) {
        alert('code: '    + error.code    + '\n' + 
              'message: ' + error.message + '\n');
    }

    // Set audio position
    // 
    function setAudioPosition(position) {
        document.getElementById('audio_position').innerHTML = position;
    }
    </script>
  </head>
  <body ng-app="starter">
    <ion-pane>
      <ion-header-bar class="bar-stable">
        <h1 class="title">Ionic Blank Starter</h1>
      </ion-header-bar>
      <ion-content>
          <title>Device Properties Example</title>
          <!-- <script type="text/javascript" charset="utf-8" src="phonegap-1.4.1.js"></script> -->
          <p id="media">Recording audio...</p>
          <p id="audio_position"></p>
      </ion-content>
    </ion-pane>
  </body>
</html>

4.运行离子模拟ios

以上应该有效 .

Note: the extension changes depending on the platform you're developing for

我正在使用与ionicframworkf和phonegap插件类似的东西..我 Build 了一个记录工厂：

startRecord，stopRecord，playRecord和Save记录到服务器......这是我的工厂文件：

/**
 * Record service
 * @module record
 * @author Claudio A. Marrero
 * @class famvoice
 */
 services.factory('$record', [

  '$rootScope',
  '$socket',
  '$account',

  function($rootScope, $socket, $account) {

    var enumerator = 0;
    var recordName = 'record-'+enumerator+'.mp3';
    var mediaRec = null;
    var OnCallback = null;
    var OnAppendData = {};

    /**
    * Start a record
    *
    * @method startRecord
    */
    function startRecord(){
      enumerator++;
      recordName = 'record-'+enumerator+'.mp3';
      mediaRec = new Media(recordName,
          function() {
          },
          function(err) {
          });
      mediaRec.startRecord();
    }

    /**
    * Stop record
    *
    * @method stopRecord
    */
    function stopRecord(){
      mediaRec.stopRecord();
    }

    /**
    * Stop record
    *
    * @method stopRecord
    */
    function playRecord(){
      mediaRec.play();
    }

    /**
    * Get the name of the record
    *
    * @method getRecord
    */
    function getRecord(){
      return recordName;
    }

    /**
    * Save the recorded file to the server
    *
    * @method save
    */
    function save(callback,appendData){
      OnCallback = callback;
      OnAppendData = appendData;
      window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, OnFileSystem, fail);
    }

    /**
    * Callback for setting the file system to persistent.
    *
    * @method OnFileSystem
    */
    function OnFileSystem(fileSystem){
      fileSystem.root.getFile(recordName, null, OnGetFile, fail);
    }

    /**
    * Callback for geting the file for disk
    *
    * @method OnGetFile
    */
    function OnGetFile(fileEntry){
      fileEntry.file(OnFileEntry, fail);
    }

    /**
    * Callback for file entry, this get the file.
    *
    * @method OnFileEntry
    */
    function OnFileEntry(file){
      var reader = new FileReader();
      reader.onloadend = function(evt) {

          var image = evt.target.result;
          var base64Data  =   image.replace(/^data:audio\/mpeg;base64,/, "");
          base64Data  +=  base64Data.replace('+', ' ');

          $socket.emit('playlists:file',{file:base64Data,name:recordName, token: $account.token(), info:OnAppendData},OnCallback);
      };
      reader.readAsDataURL(file);
    }

    /**
    * When any process of saving file fail, this console the error.
    *
    * @method OnFileEntry
    */
    function fail(err){
      console.log('Error');
      console.log(err);
    }

    /**
    * Play record
    *
    * @method playRecord
    */
    function playRecord(){
      var mediaFile = new Media(recordName,
          function() {
            console.log("playAudio():Audio Success");
          },
          function(err) {
            console.log("playAudio():Audio Error: "+err);
          }
      );
      // Play audio
      mediaFile.play();
    }

  return {
    start: startRecord,
    stop: stopRecord,
    play:playRecord,
    name:getRecord,
    save:save
  };
}]);

我希望这对你来说很有用 . :)
