FFT on the Command Line

Small utility to generate FFTs and IFFTs directly from the command line. You read the data from an ASCII file or directly from the standard in. The output is written to a specified file or to standard out.

Features:

• FFT and IFFTs
• Auto correlation function using FFT. You can choose between cyclic and linear mode
• Input and output from ASCII files or from standard in/standard out

You can download a 32-bit Linux x86 binary. Its statically linked so there should be no dependencies on other libraries. On the download page there is also a 64 bit version.

A 32 bit Windows binary is also available. However, it is dynamically linked and the fftw dll is shipped with it.
