Signal processing is used in many different areas of science and sound processing is just one of them. The package was designed to offer an easy and affordable start in to the world of signal processing. By providing three key components: FFT, FIR and SignalGenerator in combination with the ease of use and the power of Delphi, makes it a strong argument towards very expensive DSP suites. The aim of this package however is not to compete with the big ones, but to give individual users access to the most needed features when dealing with signals, without having to empty their wallet for things that they will not know how to use or need for next several years or never. Most of the standard DSP operations like: FFT, run-time filter design and filtering, decimation, interpolation, convolution can be done easily and are available within these package. A sample application: frequency equalizer is included.The components are the building blocks of the shareware FFT Properties 2.5. The functionality has been directly transfered and the user can always check the results towards a working application.
