X[i] = analogRead(0); //Reads the value from analog pin 0 (A0), quantize it and save it as a real term. sound module detector is sent to the A0 analog input of the Arduino Uno. The analog signal is sampled and quantized (digitized). Autocorrelation, weighting and tuning code is used to sum = sum + (((X[k]) - avgOffSet) * ((X[k + i]) - avgOffSet)); //X[k] is the signal and X[k+i] is the delayed version The app is fast and reliable, and is the ideal song note detector. It is a completely free app for learning music notes. Note Recognizer - App that Assists Music Learning by Detecting and Processing Musical Characteristics from Microphone in Real-Time

For example, the WEEE Directive became UK legislation in January 2007. Our entire organisation worked hard to fulfill the requirements: offSet[i] = analogRead(0); //Reads the value from analog pin 0 (A0), quantize it and save it as a real term. The detection won't extract 100% of the played notes and chords but depending on the quality of the signal it will give you useful suggests. Because the app can't separate instruments you will get the best results if just one instrument is playing at a time.
