A port of the uFFT library from C to the Odin programming language.
uFFT in Odin is a small portable Odin library for computing the discrete Fourier transform (DFT) in one dimension.
It's a port of the original uFFT from C.
Implements also Convolution, Cross-Correlation and Auto-Correlation.
The library implements forward and inverse fast Fourier transform (FFT) algorithms using both decimation in time (DIT) and decimation in frequency (DIF).
The library is written in pure C99. No compiler extensions nor assembly language are employed. It uses floating point data type and can handle unaligned data.
The FFT routines can be easily modified since their source code has less than a hundred lines. As you might expect, the uFFT performance does not outperform the performance of FFTW. The library uses one temporary array as large as the input array.
This library uses f32 and complex64 types from the Odin standard library.
