# 🎛️ LiFFT

The little FFT library.

A simple FFT and DCT2 library in a header only format that makes it easy to drop into a project and use. Performance isn't the main concern, but it's still a bit better than half the speed of [FFTPACK](https://www.netlib.org/fftpack/) or [FFTW](https://fftw.org/).
