FFT for System Audio Output

Hey guys.

I hope this question is not too trivial, but that’s why i put it in the beginner’s board :slight_smile:

I compiled and started the AudioInputExample, and of course it worked.

But what I want to do now is to get the FFT for the Audio Output that my Laptop produces, not for the input.

I thought I just have to write soundStream.setDeviceID(1) or soundStream.setDeviceID(0) in the setup(), but this did not work.

As far as I can judge it, this issue still shouldn’t be too difficult to solve, I hope?

I hope one of you guys can help me, I’d be very happy about that :slight_smile:

Have a nice day!

Greetz,

Thomas

Go download SoundFlower. It will allow you to use your laptop’s audio output to redirect it back in for use in audio applications and/or ofxFFT.
