A simple FFT wrapper for all the major desktop and mobile OSes. This library will always wrap the fastest (& most free) FFT library for your platform.

This is a fork of https://github.com/hogliux/FastFourier. The original is built as a shared library (dll), whereas this fork is built as a static library and is thus simplified somewhat (and doesn't require installation of the shared lib alongside your binaries).

This fork supports macOS, Windows x86_64, & Linux x86_64.

Nothing is required. The vDSP library (via the Accelerate framework) is already installed on all macOS systems.

You will need to download the library files for the Intel Performance Primitives (IPP). Note by running the commands below, you are accepting Intel's EULA for the IPP library.

curl --output oneapi.exe https://registrationcenter-download.intel.com/akdlm/IRC_NAS/2e89fab4-e1c7-4f14-a1ef-6cddba8c5fa7/intel-ipp-2022.0.0.796_offline.exe
./oneapi.exe -s -x -f oneapi
./oneapi/bootstrapper.exe -s -c --action install --components=intel.oneapi.win.ipp.devel --eula=accept -p=NEED_VS2022_INTEGRATION=1 --log-dir=.

The files should get installed to /Program Files (x86)/Intel/oneAPI/ipp.

You will need to download the library files for the Intel Performance Primitives (IPP). The instructions below are tested on Ubuntu 24.04. Note by running the commands below, you are accepting Intel's EULA for the IPP library.

wget -O- https://apt.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS.PUB | gpg --dearmor | sudo tee /usr/share/keyrings/oneapi-archive-keyring.gpg > /dev/null

sudo apt update
sudo apt install intel-oneapi-ipp-devel

The files should get installed to /opt/intel/oneapi/ipp.
