16-bit Real-Time Fast Fourier Transform Audio Spectrum Analyzer with AVR ATmega328P

A library for computing the Fast Fourier Transform (FFT) in one or two dimensions.

P3DFFT stands for Parallel Three-Dimensional Fast Fourier Transforms. It is a library for large-scale computer simulations on parallel platforms. It implements 3D FFT and related algorithms such as Chebyshev transform (an important class of algorithm for simulations in a wide range of fields). P3DFFT uses 2D, or pencil, decomposition.
