How can I record small size voice files in Android using Titanium?

Question

Please help me! I want to record small size voice files in Android using Titanium.

I am using Titanium.Media.AudioRecorder() to record voice files, but the size of the generated files are too large.

I would like to generate small size voice files. It doesn't matter to have low quality.

What format and what compression type should I use to get better results (small size files)? Thank you

I am using the code below:

var audioRecorder = Ti.Media.createAudioRecorder({
    format: Titanium.Media.AUDIO_FILEFORMAT_MP3,
    compression: Titanium.Media.AUDIO_FORMAT_ULAW
});

function startRecord() {
    audioRecorder.start();
}

function stopRecord() {
    record = audioRecorder.stop();
    var audioName = "some_name.mp3";
    var audioFile = Ti.Filesystem.getFile(Ti.Filesystem.externalStorageDirectory, audioName);
    audioFile.write(record);
}

If you look at the documentation you'll see that the compression and format parameters are iOS only. Android will always record default audio settings.

You either have to

• create a MediaRecorder module
• try one of those: http://gitt.io/search?q=audio (some are very old and need to be recompiled for Ti SDK 9)
• use Hyperloop to create a recorder. As a starting point you can have a look at Hyperloop MediaPlayer example

You might be able to convert this navitve MediaRecorder example to Hyperloop.
