 feature vector. Autocorrelation is correlation of a signal with its delayed copy.
+There is a webapp written in javascript which calculates autocorrelation, whose code we
+can use as it has MIT license. The repository is  <nowiki>https://github.com/cwilso/PitchDetect/</nowiki>
+If the fundamental frequency is not very strong then we will use fourier transform to get the
+frequency domain representation of the signal, then we will find frequencies at which the
+amplitude is higher. The smallest of these frequencies will be fundamental frequency. For
+example in figure given below, fundamental frequency is shown by yellow arrow.

+- Making the edges of each key rounded, so it looks similar to other blocks
+- Although actual keyboard is black and white, there should be option to change colors
+of keys.
+The way I have visualized keyboard to look is given below
