Recognition of piano notes

In this paper, an algorithm for the recognition of musical sound from piano is proposed. The music signal is first digitally sampled and transformed from the time domain to the frequency domain using Constant Q Transform. Template matching and other processing techniques are subsequently applied to detect and identify the notes. The algorithm is applied to electronically synthesised music and musical pieces performed on a piano. Perfect recognition is achieved for the electronically synthesised pieces while a high degree of accuracy is achieved for the piano pieces.Accepted versio
