Running SpectrumAnalyzer tutorial

I am very new to JUCE so this question is basic. I was running the SpectrumAnalyzer tutorial here [JUCE: Tutorial: Visualise the frequencies of a signal in real time]. I am on MacOS and using Xcode. The app compiles but when I run it, I do not see the FFT plot. It’s just a horizontal line of zeros all the way. Why may this be happening? Is it not getting access to my laptop’s mic input?

if you’re running the standalone app, you need to configure the audio settings via the Options button displayed on the GUI.

Thanks for the tutorial video :slight_smile: As for my issue, I had to enable microphone access on XCode from Projucer. This thread helped.
