This paper aims at the task of score alignment that aligns the audio recording and its corresponding score properly. Conventional methods are mostly hard to deal with the issue: the asynchrony in the recording of simultaneous notes in the score. In this paper, we propose a note-based score alignment by means of the pitch-by-time format called piano-roll(More)
Real world music pieces often present time-varying spectral shapes that normally lead to time, amplitude or frequency modulations in a phrase. Whereasthe standard Non-negative Matrix Factorization (NMF) assumes fixed spectral bases, an extension is proposed where the temporalactivations, the coefficients of the decomposition on the spectralatom basis,(More)
A system that tries to analyze polyphonic musical recordings of bowed-string instruments, extract synthesis parameters of individual instrument and then re-synthesize is proposed. In the analysis part, multiple F0s estimation and partials tracking are performed based on modified WGCDV (weighted greatest common divisor and vote) method and high-order HMM.(More)

In this paper, we presented a flexible analysis/re-synthesis method for smoothly changing the properties of isolated notes in pol-yphonic instrumental music recordings. True Envelope Linear Predictive Coding (TELPC) method has been employed as the analysis/synthesis model in order to preserve the original timbre quality as much as possible due to its(More)
