Transient Preservation Under Transformation in an Additive Sound Model
نویسندگان
چکیده
We introduce the use of the method of reassignment in sound modeling to produce a sharper, more robust additive representation. The Reassigned Bandwidth-Enhanced Additive Model follows ridges in a time-frequency analysis to construct partials having both sinusoidal and noise characteristics. This model yields greater resolution in time and frequency than is possible using conventional additive techniques, and preserves the temporal envelope of transient signals, even in modified reconstruction, without introducing new component types or complicated phase interpolation algorithms.

On the Use of Time–Frequency Reassignment in Additive Sound Modeling*
The method of reassignment has been used to sharpen spectrograms in order to make them more readable [1], [2], to measure sinusoidality, and to ensure optimal window alignment in the analysis of musical signals [3]. We use time–frequency reassignment to improve our bandwidthenhanced additive sound model. The bandwidth-enhanced additive representation is in some way similar to traditional sinuso...
متن کاملAdditive Synthesis Based on the Continuous Wavelet Transform: a Sinusoidal plus Transient Model
In this paper a new algorithm to compute an additive synthesis model of a signal is presented. An analysis based on the Continuous Wavelet Transform (CWT) has been used to extract the time-varying amplitudes and phases of the model. A coarse to fine analysis increases the algorithm efficiency. The computation of the transient analysis is performed using the same algorithm developed for the sinu...
متن کاملApplication of an Additive Self-tuning Controller for Static Synchronous Series Compensator for Damping of Sub-synchronous Resonance Oscillations
In this paper, an additive self-tuning (ST) control scheme is presented for a static synchronous series compensator (SSSC) to improve performance of conventional PI control system for damping sub-synchronous resonance (SSR) oscillations. The active and reactve series compensation are provided by a three-level 24-pulse SSSC and fixed capacitor. The proposed ST controller consists of a pole shift...
متن کاملTransient expression of green fluorescent protein in radish (Raphanus sativus) using a turnip mosaic virus based vector
It is possible to use transgenic plants, as bioreactors, for the production of recombinant inexpensive chemicals and drug components. Transient gene expression is an appropriate alternative to stable transformation because it allows an inexpensive and rapid method for expression of recombinant proteins in plant tissues. In recent years, plant viral vectors have been increasingly developed as su...
