| Résumé |
This paper discusses an additional signal processing procedure for use in a recently proposed frequency-domain additive synthesizer. The overlap-add approach used in the frequency-domain synthesis can result in amplitude modulation in the overlap region between successive time frames if the partial frequencies in those frames are significantly different. A new method is proposed in which sinusoids of linearly time-varying frequency (chirps) are used to accommodate the frame-to-frame frequency changes.
