Discrete Fourier transform (DFT), inverse DFT (IDFT), and circular convolution are important tools for analyzing and designing discrete signals and systems, and are widely used in various industries.

This paper proposes the use of a synchronized linear transform, the synchronized short-time-Fourier-transform (sSTFT), for time-frequency analysis of anechoic mixtures. We address the short comings of ...

Synopsis mpFFT is an open-source project to implement a high-performance multiprecision Fast Fourier Transform that can compete with non-free software as Mathematica and MATLAB, in both serial and ...
