Signal Input/Output
Measure the main frequency of analog captured signal connected to an Arduino and check for noise and mute.
Detects frequency from 38 Hz to 9612 Hz and works even on an ATTiny85 with 1 MHz up to 4806 Hz. Signal can be delivered e.g. by a microphone. New: Renamed printSignalValuesForArduinoPlotter() to printInputSignalValuesForArduinoPlotter() etc.

This library is compatible with the avr architecture so you should be able to use it on the following Arduino boards:
Note: while the library is supposed to compile correctly on these architectures, it might require specific hardware features that may be available only on some boards.
To use this library, open the Library Manager in the Arduino IDE and install it from there.
