C# wrapper for FFTS (The Fastest Fourier Transform in the South)

This is a Python GUI Application Developed by Anshuman Biswal to Perform Fast Fourier Transform (FFT) on a given Signal Sequence, it is written in Python 3.8 and TKinter. Users can find DFT and IDFT of 4-Point,8-Point signal sequence in Frequency and Time Domain using Radix Algorithm, Also Linear Convolution and Circular Convolution using Radix.

VectorFFT: A permutation-free mixed-radix FFT library that beats Intel MKL and FFTW on every tested size. Hand-tuned AVX2/AVX-512 codelets for 18 radixes, zero-allocation in-place execution, and a wisdom-based planner. 1.1x–4.9x faster than Intel MKL, 1.3x–12.8x faster than FFTW. Pure C, no dependencies.

Audio Fingerprinting and Recognition in C++

A rust port of numpy and scipy using modern algorithms and multithreading. Built for speed, precision and performance.

Wake word detection using Tiny ML. Tensorflow lite is used here. The project has been done by refering the text book, Tiny ML by O' Reilly.
