Hi,  
I just noticed that the [Frequency Spectrum](https://p5js.org/examples/sound-frequency-spectrum.html) example differs between edge and chrome.

Any idea which browser is right or what the reason could be?

There must be a time lag between these browsers. Try to whistle and observe the spectra. Unfortunately the spectrum is not displayed in my Edge browser.

I whistled a lot. It‘s not a delay issue

Well If you are possession of a calibrated tuning fork, you can try to check the validity of the spectrum. Or you can use one of those popular android apps called frequency generators. Wish You’d Better Luck This TIme !
