The purpose of this article is to investigate the application of DFT-modulated filter bank in systems with significant spectral component amplification like hearing aid. There is a description of analysis / synthesis method based on short-time Fourier transform (STFT). which is used in most systems of speech information processing. It is shown that DFT-modulated filter bank is a gener... https://www.jmannino.com/quick-save-Lax-aire-3-oz-great-buy/
