Frequently Asked Questions (FAQ)

How does the spectrum analyzer work?
It uses an AnalyserNode to compute a Fast Fourier Transform (FFT) on incoming audio signals, mapping frequency magnitudes to visual bars.
Does this require microphone permissions?
Only if you select the live microphone mode. You can also run the visualizer with the built-in polyphonic synthesizer without granting any permissions.
