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://fitnessgravesyardes.shop/product-category/speakers/
