Resumen:
The inverse FFT method was proposed to alleviatethe complexity of the additive sound synthesis method in realtime applications, and consists in synthesizing overlapping blocksof samples in the frequency domain. However, its application islimited by its inherent trade-off between time and frequencyresolution. In this paper we propose an alternative methodfor overcoming this limitation. The proposed method generatestime-frequency noise with an auto-correlation function such thatthe sound obtained after converting it to time domain has thedesired time-varying power spectral density. We present synthesisexamples illustrating the simultaneously good time and frequencyresolution of the proposed method and study its complexity.
