Do you need to hook up the audio shield or DAC of the Teensy in order for AudioAnalyzeNoteFrequency to work? I uploaded NoteFrequency example sketch to my Teensy and Serial never output anything, and when I printed out notefreq.available() it always returned 0. I'm getting the audio shield soon enough, I just wanted to check ahead of time to see if I'm doing something wrong or if you do need to hook up the DAC/Audio shield in order for the example sketch to work. This is on a Teensy 4.0 using Arduino IDE on Linux.
