Sumario:The main objective is the estimation of musical statistics such as beat time, tempo and duration applied to the development of a comparison system between musicians. The final objective of the work is to develop an application that allows the user to analyze the recording of their performance and compare it with another performance. Our application is based on four stages: training, alignment, extraction of musical statistics and comparison. We propose an alignment method, which allows estimating the audio-to-score alignment with a variable cost function guided by a regularization constant (λ). In addition, the algorithm that allows extracting musical statistics and a comparison system between performances have been developed. The development of the alignment algorithm has been carried out in MatLab, for tests, and in C, for the final application. And the other modules that make up the application are developed in MatLab.
