In this article the estimation of the spectral envelope of sound signals is addressed. The intended application for the developed algorithm is pitch shifting with preservation of the spectral envelope in the phase vocoder. As a first step the different existing envelope estimation algorithms are investigated and their specific properties discussed. As the(More)
Several versions of Sinusoidal+Residual analysis/synthesis models have been developed for music applications. They have been very successful and are already found in commercial and experimental tools used by musicians as well as researchers. In this paper, we begin by presenting the principles of this now classical model. However, the standard version of(More)
Music alignment links events in a score and points on the audio performance time axis. All the parts of a recording can be thus indexed according to score information. The automatic alignment presented in this paper is based on a dynamic time warping method. Local distances are computed using the signal’s spectral features through an attack plus sustain(More)
In this paper we present the implementation of an online HMM decoding process. The algorithm derives an online version of the Viterbi algorithm on successive variable length windows, iteratively storing portions of the optimal state path. We explicit the relation between the hidden layer's topology and the applicability and performance prediction of the(More)
This paper presents a frame-based system for estimating multiple fundamental frequencies (F0s) of polyphonic music signals based on the short-time Fourier transform (STFT) representation. To estimate the number of sources along with their F0s, it is proposed to estimate the noise level beforehand and then jointly evaluate all the possible combinations among(More)
This article is concerned with the estimation of fundamental frequencies, or F0s, in polyphonic music. We propose a new method for jointly evaluating multiple F0 hypotheses based on three physical principles: harmonicity, spectral smoothness and synchronous amplitude evolution within a single source. Based on the generative quasiharmonic model, a set of(More)
In this paper we present a new Analysis/Synthesis method named SINOLA, which benefits from both sinusoidal additive model and OLA/PSOLA method, and which allows adequate processing according to the inherent local characteristics of the signal. All the parameters of the models are derived at the same time from spectrum analysis. We propose an analytical(More)
