description: This article describes proposed methods in the field of pitch estimation in polyphonic melodies and note onset detection in musical fragments. When implementing the methods, a special frequency-dependent time-frequency analysis tool called RTFI was used. RTFI can easily provide time-frequency analysis with different time-frequency resolutions, for example, with a resolution similar to the frequency analyzer of the human ear, as well as with a resolution of uniform and constant Q-factor. As part of the onset detection problem, two methods are proposed that work with the signal energy and its frequency. For estimating pitch in polyphony, two methods were also proposed, one of which analyzes the ratio of frequency harmonics, and the other one is a support vector method for solving a classification problem. These methods are used to implement two automatic transcription systems, where automatic transcription is a process in which parameters indicating the pitch and the onset time of each note are extracted respectively. The effectiveness of the proposed methods and the systems formed on their basis is evaluated by calculating the accuracy, recall and F-measure values. It is shown that for real musical fragments, the proposed systems of automatic transcription of musical fragments work better than a number of the existing ones considered. In addition, the system based on the support-vector method for determining pitch has great potential for further optimization and achieving even greater efficiency in future work.
