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)
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)
In this paper, we presented a flexible analysis/re-synthesis method for smoothly changing the properties of isolated notes in polyphonic 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)
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)
