Multithreaded FFT library written in pure Java
JTransforms is the first, open source, multithreaded FFT library written in pure Java. Currently, four types of transforms are available Discrete Fourier Transform DFT, Discrete Cosine Transform DCT, Discrete Sine Transform DST and Discrete Hartley Transform DHT. The code is derived from General Purpose FFT Package written by Takuya Ooura and from Java FFTPack written by Baoshe Zhang.
