Audio Frequency Detector - Arduino Project Hub
https://create.arduino.cc/projecthub/lbf20012001/audio-frequency-detector-617856
This Arduino project displays the approximate frequency of the loudest sound detected by a sound detection module. For this project, the analog output from the sound module detector sends the analog audio signal detected to A0 of the Arduino Uno. The analog signal is sampled and quantized (digitized). A Fast Fourier Transform (FFT) is then performed on the …

As a follow up to the Arduino Audio Input tutorialthat I posted last week, I wrote a sketch which analyzes a signal coming into the Arduino's analog input and determines the frequency. The code uses a sampling rate of 38.5kHz and is generalized for arbitrary waveshapes. I've also turned the LED attached to pin 13 into a clipping indicator, so you know if you need to adjust your signal's …

To set the frequency response in relation to your human speed, the frequency range for a man speaking is between 100Hz and 120Hz and for women around 300Hz. KY-038 / KY-037 Impedance Impedance is the measure of the total opposition of a circuit to current that considers the resistance and the effects of the capacitance and the inductance.

https://electronics.stackexchange.com/questions/10371/sound-sensor-that-can-give-feedback-on-the-amplitude-of-different-frequencies
The sensors I'm finding in my search however only support level of sound it seems. Is it possible to get the level of individual frequency ranges from one sensor, or does it require multiple senors? I'm new to this so don't know the exact terminology, but essentially I want to create something that can respond to a set of different frequencies ...
