Hello World

- 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

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

from native import app

file = "/sdcard/demofile.wav"

def OnStart():
    global rec
    rec = app.CreateAudioRecorder()
    rec.SetFile( file )
    rec.Start()

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

def StopRecording():
    rec.Stop()
    app.ShowPopup( "Finished recording. Now playing" )

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