This should work. Also you can look at CameraExample.

AudioGrabber *audioGrabber = new AudioGrabber;

AudioFormat format;
format.setChannelCount(2);
format.setSampleRate(44100);
format.setFormat(AudioFormat::SignedInt16);

audioGrabber->setFormat(format);
audioGrabber->setDeviceIndex(0);

Recorder *recorder = new Recorder;
recorder->setAudioGrabber(audioGrabber);

AudioCodecSettings settings;
settings.setSampleRate(audioGrabber->format().sampleRate());
settings.setChannelCount(audioGrabber->format().channelCount());
settings.setSampleFormat(EncoderGlobal::Signed16);

recorder->encoder()->setAudioCodecSettings(settings);
recorder->encoder()->setAudioCodec(EncoderGlobal::MP3);
recorder->encoder()->setFilePath("C:/audio.mp3");
recorder->start();

What do you mean by "init"? Where is it? Inside Recorder?

cygnus2k commented 8 years ago

in the mainwindow.cpp empty template:

MainWindow::MainWindow(QWidget *parent) :

QMainWindow(parent),

ui(new Ui::MainWindow)

{

AudioGrabber *m_audioGrabber = new AudioGrabber;

Tanks
