DSP Filter is a powerful digital filter processing (DSP) program designed to enable you to filter the audio input (microphone) with one of several filters and then output it to the computer speakers.
The program has been designed to work with communications receivers for professional and amateur use. Using the spectrum display you can drag a filter onto a signal of interest (SOI) and filter that signal with either a fixed bandpass filter, a variable bandpass filter, or a notch filter. In addition, one of two noise reduction filters are available to filter the total spectrum.
