Project description and goal: Basically a beat-detection device with a very small formfactor. I am using an Arduino Uno as a prototyping device, but I have an Arduino Mega, Sparkfun Micro and several other development boards. it stock to use if needed. I want the microcontroller to read analog audio, convert it to FFT or FHT or.

The idea of this project is to use Arduino to detect beats in music in line level (like the red and white RCA cables of audio). The analog input of the Arduino can only accept from 0v to 5v DC. An audio signal is an AC signal. So, how to get the negative part of the wave of an audio signal? We must bias to 2,5v.

Then to detect each beat you can make an envelope detector circuit with a resistor and rectifier charging a capacitor. The capacitor and its charge and discharge resistors values detrmine how much filtering of the cycles occurs. Its output can be squared with an opamp or Cmos Schmitt-trigger and used to clock a 4017 stepper.
