I am writing a code to identify the frequency of a musical note. The problem is, the notes are being wrongly identified for some notes in the same order. For example, it correctly identified a C note as having 261 Hz frequency, making it a middle C note, but it identified E after it as having frequency of 270 or so, making it a C# note. The problems are not consistent. I even tried getting an online repository of notes recorded in a soundless studio, but audacity returns a different peak frequency than what I had expected. How should I proceed further? This is the main point of the entire project.

@Samyukta Ramnath: Consider what you have written so far. Paraphrased it is: "My code does not created the wanted results". So how could we help based on this information?

Of course the only way to go is to find the bug or design error in your code. You could post the relevant part of it here. Usually codes with more than 30 lines catches less attraction than compact ones.
