CreateAudioRecorder

Hello World

Content:
- Methods

The AudioRecorder object can be used to listen for sound and record it to a file.

rec = app.CreateAudioRecorder() → app object: AudioRecorder

After creation you have to define the recording file with the SetFile Method:
rec.SetFile( "/sdcard/demofile.wav" );

After that you can Start the recording: rec.Start();

The recorded audio will then be written to the specified file.

Finally you can also Stop the recording: rec.Stop();

Example - Example

function OnStart()
{
    rec = app.CreateAudioRecorder();
    rec.SetFile( "/sdcard/demofile.wav" );
    rec.Start();

    app.ShowPopup( "Please speak" );
    setTimeout( StopRecording, 5000 );
}

function StopRecording()
{
    rec.Stop();
    app.ShowPopup( "Finished recording. Now playing" );

    ply = app.CreateMediaPlayer();
    ply.SetFile( file );
    ply.SetOnReady( ply.Play );
}
