TarsosDSP, IllegalStateException

Question

I'm using TarsosDSP for an android project, and I'm getting this error:

Unable to start activity ComponentInfo{com.example.song2sheet/com.example.song2sheet.RecordingActivity}: java.lang.IllegalStateException: startRecording() called on an uninitialized AudioRecord.

From what I've read, to start taking samples all I need is this

        AudioDispatcher dispatcher = AudioDispatcherFactory.fromDefaultMicrophone(22050, 1024, 0);
        PitchDetectionHandler detectionHandler = new PitchDetectionHandler() {
            @Override
            public void handlePitch(PitchDetectionResult pitchDetectionResult, AudioEvent audioEvent) {
                final float pitchInHz = pitchDetectionResult.getPitch();
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        sampledFrequency = pitchInHz;
                    }
                });
            }
        };
        AudioProcessor pitchProcessor = new PitchProcessor(PitchProcessor.PitchEstimationAlgorithm.FFT_PITCH, 22020, 1024, detectionHandler);
        dispatcher.addAudioProcessor(pitchProcessor);

        Thread recordingThread = new Thread(dispatcher, "Recording Thread");
        recordingThread.start();

but as seen above I'm getting an IllegalStateException.

Am I missing something from this code, as the error is being thrown on the first line?

Any help would be grand.

Thanks.
