Hi,
i'm trying to build a tone detector which is able to detect main frequency in an audio signal acquired by an amplified mic (20db) on Arduino/Teensy.
This is the mic -> http://electropit.com/index.php/2015/12/20/fc-109-max9812-microphone-amplifier-module/
Since the range i'm inspecting is very specific (50 to 205 Hz and 400 to 800 Hz) but i'm listening to very low sound, i'm looking for something that can give me a good resolution in amplitude AND in frequency. What i want to build is a sorta of guitar tuner that can hear very weak sound. I've analyzed the signal which is around 3.5mV.
I've tried the FreqMeasure library on an ArduinoMega, but i can only read frequency of very strong signal... i'm wondering if with Teensy 3.2, due to its higher resolution, i can work on such low amplitude...
Will Teensy help me?
EDIT: audio signal acquired by an amplified mic (20db) on Arduino/Teensy... in REALTIME
