Phase Bashing for sample-Based formant synthesis
Many techniques have been proposed for synthesizing the sung or spoken voice; they generally fall into two classes. First, the purely synthetic techniques (FM, FOF, PAF, ...) make sounds with specified formant frequencies, bandwidths, and amplitudes. Second, the sample-based methods (LPC, Vocoders, PSOLA, ...) reconstruct sounds from pre-recorded speech or singing. Here we present a technique t...
متن کاملDetection of random alterations to time-varying musical instrument spectra.
The time-varying spectra of eight musical instrument sounds were randomly altered by a time-invariant process to determine how detection of spectral alteration varies with degree of alteration, instrument, musical experience, and spectral variation. Sounds were resynthesized with centroids equalized to the original sounds, with frequencies harmonically flattened, and with average spectral error...
متن کاملObject-Based Sound Synthesis
The physical modeling of complex sound generators would be feasible if approached by individually synthesizing and discretizing the objects that contribute to the generation of sounds. This raises the problem of show to correctly implement the interaction between these objects. In this paper we show how to synthesize sounds in an object-based fashion, i.e. by building objects individually synth...
متن کاملA 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...
متن کاملFormant-based Audio Synthesis Using Nonlinear Distortion
An audio synthesis technique (\Phase Aligned Formant synthesis") is presented which is aimed at real-time musical applications. A desired sound is speciied in terms of one or several time-varying formants, each with speciied center frequencies, bandwidths, and amplitudes. The sound produced may be periodic or noisy. The relative merits of other known real-time techniques for synthesizing sounds...
