Fast Fourier Transform and other Signal Processing tools

Google

Here are FFT tools that I use:  www.i-s-r.com.  Also click Software.  National Instruments Measurement Studio ActiveX controls are described.  The analysis ActiveX control that is part of that package provides a powerful set of tools for FFT and other signal processing.

MatrixVB from MathTools is A COM library of matrix math functions for Visual Basic, making it an easy to use math interpreter and scientific development environment. MatrixVB includes functions for calculating FFTs and for 600 matrix manipulation functions. You can download an evaluation version from the MathTools web site.

Newcastle Scientific offers an ActiveX / OCX based numerical library which includes easy to call functions for Linear and Non-Linear Least Squares Fitting, Fast Fourier Transforms (FFT), Signal Processing, Kalman Filtering, Cubic Spline Interpolation, Root/Minimum/Maximum Searching, Encryption, Numeric Sorting, and others.  It includes example Visual Basic source code and instructions.

I have found one Visual Basic example that has some nice feature, though it has limited documentation.  Take a look at the FFT code on http://home.surewest.net/galen.
