capture.captureAudio

Start the audio recorder application and return information about captured audio clip files.

navigator.device.capture.captureAudio(
    CaptureCB captureSuccess, CaptureErrorCB captureError,  [CaptureAudioOptions options]
);

Description

Starts an asynchronous operation to capture audio recordings using the device's default audio recording application. The operation allows the device user to capture multiple recordings in a single session.

The capture operation ends when either the user exits the audio recording application, or the maximum number of recordings specified by [CaptureAudioOptions](captureAudioOptions.html).limit is reached. If no limit parameter value is specified, it defaults to one (1), and the capture operation terminates after the user records a single audio clip.

When the capture operation finishes, the CaptureCallback executes with an array of [MediaFile](MediaFile.html) objects describing each captured audio clip file. If the user terminates the operation before an audio clip is captured, the CaptureErrorCallback executes with a [CaptureError](CaptureError.html) object, featuring the [CaptureError](CaptureError.html).CAPTURE_NO_MEDIA_FILES error code.

Supported Platforms

  • Android
  • BlackBerry WebWorks (OS 5.0 and higher)
  • iOS
  • Windows Phone 7 and 8
  • Windows 8

Quick Example

// capture callback
var captureSuccess = function(mediaFiles) {
    var i, path, len;
    for (i = 0, len = mediaFiles.length; i < len; i += 1) {
        path = mediaFiles[i].fullPath;
        // do something interesting with the file
    }
};

// capture error callback
var captureError = function(error) {
    navigator.notification.alert('Error code: ' + error.code, null, 'Capture Error');
};

// start audio capture
navigator.device.capture.captureAudio(captureSuccess, captureError, {limit:2});

BlackBerry WebWorks Quirks

  • Cordova for BlackBerry WebWorks attempts to launch the Voice Notes Recorder application, provided by RIM, to capture audio recordings. The app receives a [CaptureError](CaptureError.html).CAPTURE_NOT_SUPPORTED error code if the application is not installed on the device.

iOS Quirks

  • iOS does not have a default audio recording application, so a simple user interface is provided.

Windows Phone 7 and 8 Quirks

  • Windows Phone 7 does not have a default audio recording application, so a simple user interface is provided.
