Time–Frequency Synthesis of Noisy Sounds With Narrow Spectral Components

A unified time-frequency method for synthesizing noisy sounds with short transients and narrow spectral components

The inverse FFT method was proposed to alleviate the complexity of the additive sound synthesis method in real time applications, and consists in synthesizing overlapping blocks of samples in the frequency domain. However, its application is limited by its inherent trade-off between time and frequency resolution. In this paper we propose an alternative method for overcoming this limitation. The...

Spatialized Synthesis of Noisy Environmental Sounds

In this paper, an overview of the stochastic modeling for analysis/synthesis of noisy sounds is presented. In particular, we focused on the time-frequency domain synthesis based on the inverse fast Fourier transform (IFFT) algorithm from which we proposed the design of a spatialized synthesizer. The originality of this synthesizer remains in its one-stage architecture that efficiently combines ...

Frequency ratios of spectral components of musical sounds

A recently developed high resolution frequency tracker @J. C. Brown and M. S. Puckette, ‘‘A high resolution fundamental frequency determination based on phase changes of the fourier transform,’’ J. Acoust. Soc. Am. 94, 662–667 ~1993!# has made it possible to measure the ratios of the frequencies of the upper harmonics of a sound with respect to its fundamental frequency with high accuracy. Calc...

Analysis/synthesis and Spatialization of Noisy Environmental Sounds

The use of stochastic modeling is discussed for analysis/synthesis and transformation of environmental sounds. The method leads to perceptually relevant synthetic sounds based on the analysis of natural sounds. Applications are presented, such as sound effects using parametric signal transformations, or data compression. Moreover, we propose a method which efficiently combines the stochastic mo...
