An audio synthesis technique, "phase-aligned formant synthesis," is presented which is aimed at real-time musical applications. A desired sound is specified in terms of one or several time-varying formants, each with specified 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 with desired formants are also discussed. As an example, a spoken word is analyzed and resynthesized.
