Recently I’m trying to use JUCE to play audio.
After one day and a half I still can’t successfully made it. The related code is:
/* MyWindow.h */
class MyWindow : public DocumentWindow
{
public:
static MyWindow* ptr;
MyWindow();
void closeButtonPressed() override;
void paint(Graphics&) override;
private:
Font f;
AudioFormatManager* afm;
AudioFormatReader* afr;
AudioFormatReaderSource* afrs;
AudioTransportSource* ats;
AudioDeviceManager* adm;
AudioSourcePlayer* asp;
TimeSliceThread* tst;
JUCE_DECLARE_NON_COPYABLE(MyWindow);
};
/* MyWindow.cpp */
MyWindow::MyWindow(): DocumentWindow("GUI Test", Colours::lightgrey, DocumentWindow::minimiseButton | DocumentWindow::closeButton), f("Times New Roman", 20, Font::plain), afm(0), afr(0), afrs(0), ats(0), adm(0), asp(0), tst(0)
{
setUsingNativeTitleBar(1);
setVisible(1);
Desktop::getInstance().setGlobalScaleFactor(1.0);
centreWithSize(640, 480);
//=============================================
afm=new AudioFormatManager();
afm->registerBasicFormats();
afr=afm->createReaderFor(File("test.ogg"));
afrs=new AudioFormatReaderSource(afr, 1);
afrs->setLooping(1);
tst=new TimeSliceThread("testThread");
ats=new AudioTransportSource();
ats->setSource(afrs, 2^15, tst, afr->sampleRate, 2); //******************
ats->setPosition(0.);
asp=new AudioSourcePlayer();
asp->setSource(ats);
adm=new AudioDeviceManager();
adm->initialiseWithDefaultDevices(0, 2);
adm->addAudioCallback(asp);
ats->start();
return;
}
And I tried to replace the statement in constructor MyWindow::MyWindow()
“ats->setSource(afrs, 2^15, tst, afr->sampleRate, 2);” with
“ats->setSource(afrs, 0, 0, afr->sampleRate, 2);” (the line with lots of “*” in comment), then I found it could successfully work.
So I know that I have using the TimeSliceThread class in wrong way.
And the question is how I can correctly use the class TimeSliceThread in AudioTransportSource::setSource? Thanks.
