sleekfft_rs

sleekfft_rs is a module written in pure Rust which provides efficient functions to perform fast fourier transform of power of two sized signals. It also provides a convolution function which performs convolution between two real signals.

This module only provides fft functions for double precision floating point numbers.

It utilizes hardware SIMD instructions to accelerate the algorithms. No special code is needed to utilize SIMD. The Fft struct will choose the best SIMD instruction available dynamically. This crate often beats FFTW and RustFFT in terms of performance.

Currently only x86 SIMD instruction set (SSE2, AVX, FMA) is supported. On any other platform it will use scalar operations.
