Cordova Audio Recorder API Plugin

Notes:

THIS REPO WAS OPTIMIZED FOR LeySerKids, A BRAND OF GRAPECITY INC.

The major enhancements are:

• You can change the quality of output file by the bitrate arguments of the record method in kbps, DEFAULT_BIT_RATE_KBPS is 32.
• You can check the permission of accessing microphone by checkPermission
• You can retrieve the duration of an audio file by getDuration in ms

Introduction:

This plugin is a Cordova audio recorder plugin that works as API.

Different than http://plugins.cordova.io/#/package/org.apache.cordova.media-capture this plugin does not request the native recorder app (system default recorder) and active recording manually.

Supports platforms:

• iOS
• Android

Install:

$ cordova plugin add https://github.com/leyserkids/cordova-plugin-audio-recorder-api.git

How to use:

var recorder = new Object;
recorder.checkPermission = function() {
  window.plugins.audioRecorderAPI.checkPermission(function(result) {
    // success
	if(result === window.plugins.audioRecorderAPI.PERMISSION_GRANTED){
		alert('permission granted');
	}else{
		alert('permission denied or unditermined.');
	}
  }, function(msg) {
    // failed
    alert('ko: ' + msg);
  });
}
recorder.stop = function() {
  window.plugins.audioRecorderAPI.stop(function(msg) {
    // success
    alert('ok: ' + msg);
  }, function(msg) {
    // failed
    alert('ko: ' + msg);
  });
}
recorder.record = function() {
  window.plugins.audioRecorderAPI.record(function(msg) {
    // complete
    alert('ok: ' + msg);
  }, function(msg) {
    // failed
    alert('ko: ' + msg);
  }, 30, 16); // record for 30 seconds, low quality (16kbps)
}
recorder.playback = function() {
  window.plugins.audioRecorderAPI.playback(function(msg) {
    // complete
    alert('ok: ' + msg);
  }, function(msg) {
    // failed
    alert('ko: ' + msg);
  });
}
recorder.getDuration = function(filePath) {
  window.plugins.audioRecorderAPI.getDuration(filePath,function(durationInSecs) {
    // ok
    alert('ok: Duration is ' + durationInSecs/1000 + 'sec');
  }, function(msg) {
    // failed
    alert('ko: ' + msg);
  });
}

Where are files save?

iOS: /var/mobile/Applications/<UUID>/Library/NoCloud/<file-id>.m4a Android: /data/data/<app-id>/files/<file-id>.m4a

Copy File to Another Place

Example with file plugin: http://ngcordova.com/docs/plugins/file/

iOS: /var/mobile/Applications/<UUID>/Documents/new_file.m4a Android: <sdcard>/new_file.m4a

window.plugins.audioRecorderAPI.record(function(savedFilePath) {
  var fileName = savedFilePath.split('/')[savedFilePath.split('/').length - 1];
  var directory;
  if (cordova.file.documentsDirectory) {
    directory = cordova.file.documentsDirectory; // for iOS
  } else {
    directory = cordova.file.externalRootDirectory; // for Android
  }
  $cordovaFile.copyFile(
    cordova.file.dataDirectory, fileName,
    directory, "new_file.m4a"
  )
    .then(function (success) {
      alert(JSON.stringify(success));
    }, function (error) {
      alert(JSON.stringify(error));
    });
}, function(msg) {
  alert('ko: ' + msg);
}, 3, window.plugins.audioRecorderAPI.DEFAULT_BIT_RATE_KBPS);
