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 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)
Generalized Diphone Control is a powerful means of building a musical phrase from dictionaries of analysed sound units by building sequences of units and concatenating and articulating them. We present new developments and features of the program Diphone 2.0, additive analysis ported on Macintosh, control of the Chant synthesis model and a Chant synthesis(More)
This paper deals with the automatic generation of music audio summaries from signal analysis without the use of any other information. The strategy employed here is to consider the audio signal as a succession of " states " (at various scales) corresponding to the structure (at various scales) of a piece of music. This is, of course, only applicable to(More)
CUIDADO is a new project (European I.S.T. Project) which aims at providing content-based music applications (Vinet, Herrera, and Pachet 2002). Among these applications is an authoring tool for managing sample databases including search by similarity, search by textual attributes but also a system allowing automatic sound classification based on predefined(More)
As soon as the beginning of the 600s, the singing voice have been synthesized by computer. Since these first experiments, the musical and natural quality of singing voice synthesis has largely improved and high quality commercial applications can be envisioned for a near future. This talk gives an overview of synthesis methods, control strategies and(More)
We propose a new generative model for polyphonic music based on nonlinear Independent Subspace Analysis (ISA) and factorial Hidden Markov Models (HMM). ISA represents chord spectra as sums of note power spectra and note spectra as sums of instrument-dependent log-power spectra. HMM models note duration. Instrument-dependent parameters are learnt on solo(More)
AudioSculpt is an application for the musical analysis and processing of sound files. The program allows very detailed study of a sound's spectrum, waveform, fundamental frequency and partial contents. Multiple algorithms provide automatic segmentation of sounds. All analyses can be edited, stored and used to guide processing within the application, such as(More)
