A Multi-pitch Tracking System (mirex 2009)
نویسندگان
چکیده
This extended abstract describes the system we submit for MIREX 2009 task “Multiple Fundamental Frequency Estimation and Tracking”. The task includes three subtasks: 1) Multi-pitch Estimation (MPE) at frame-level, 2) note events detection and 3) pitch tracking for each source. Our system consists of two parts: 1) MPE in each time frame and 2) pitch trajectory formation from these pitch estimates. We submit two versions of the system. The first one implements the whole system and does all the three subtasks. The second one only implements the MPE part and does the first subtask. For the first subtask the two versions output different results, since the first version refines MPE results with tracking results.

Multiple Fundamental Frequency Extraction for Mirex
This extended abstract outlines an efficient approach for the extraction of multiple fundamental frequencies (F0) from polyphonic musical audio. The algorithm consists of three analysis steps. At first a multi-resolution spectral analysis is performed on the audio signal. Then, the most salient pitches are identified using a pitch extraction algorithm, which is designed to identify the predomin...

متن کاملEvaluation of Multiple-F0 Estimation and Tracking Systems
Multi-pitch estimation of sources in music is an ongoing research area that has a wealth of applications in music information retrieval systems. This paper presents the systematic evaluations of over a dozen competing methods and algorithms for extracting the fundamental frequencies of pitched sound sources in polyphonic music. The evaluations were carried out as part of the Music Information R...
