Non-stationary Analysis/Synthesis using Spectrum Peak Shape Distortion, Phase and Reassignment
نویسندگان
چکیده
A new Analysis/Synthesis method, named SINOLA, based on “sinusoidal additive” and “OLA/PSOLA” synthesis, is proposed. It allows high quality transformation of both stationnary and non-stationnary parts of a signal. Time-frequency characterization and synthesis parameters estimation is done by a novel method based on spectrum peak shape distortions and time-frequency phase evolutions.

SINOLA: A New Analysis/Synthesis Method using Spectrum Peak Shape Distortion, Phase and Reassigned Spectrum
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 formulation of a Complex Short-Time Spectr...
متن کاملIdentification of Nonstationary Audio Signals Using the FFT, with Application to Analysis-based Synthesis of Sound
In the analysis of sound (for synthesis), digitally sampled audio is processed to extract certain features. The resulting data can be synthesised to reproduce the original sound, or modified before synthesis to musically transform the sound. The analysis primarily uses a harmonic model, which considers a sound to be composed of multiple nonstationary sinusoids. The first stage of analysis is of...
متن کاملNonlinear and Non-stationary Vibration Analysis for Mechanical Fault Detection by Using EMD-FFT Method
The Hilbert-Huang transform (HHT) is a powerful method for nonlinear and non-stationary vibrations analysis. This approach consists of two basic parts of empirical mode decomposition (EMD) and Hilbert spectral analysis (HSA). To achieve the reliable results, Bedrosian and Nuttall theorems should be satisfied. Otherwise, the phase and amplitude functions are mixed together and consequently, the ...
متن کاملGeneralization of the Derivative Analysis Method to Non-Stationary Sinusoidal Modeling
In the context of non-stationary sinusoidal modeling, this paper introduces the generalization of the derivative method (presented at the first DAFx edition) for the analysis stage. This new method is then compared to the reassignment method for the estimation of all the parameters of the model (phase, amplitude, frequency, amplitude modulation, and frequency modulation), and to the CramérRao b...
متن کاملGreen Extracellular Synthesis of the Silver Nanoparticles Using Thermophilic Bacillus Sp. AZ1 and its Antimicrobial Activity Against Several Human Pathogenetic Bacteria
Background: Silver nanoparticles (AgNPs) are among the most effective antimicrobial agents that are used in the medicine and pharmaceutics. During the past decades, metal nanoparticles synthesis through application of the biological methods has increasingly been used, as the biologically synthesized particles are mostly non-toxic as well as effective. Objectives: The main goal for undertaking t...
