Teensy 3.2 Spectrum analyzer

Thanks, johnwasser.
Yes, that's right.

Hey! I see now that Nick replied to my message! I thought he wasn't reading there anymore!

He says:

The range will be from just above 50hz (or down to 10hz if your hardware is good enough to set m_shift = 0.1) to 22khz.

I don't understand... You're right: const int sampleRate = 16384;
Why does he say "to 22kHz"?
I ask him...

Thank you for your help!
