Fast Fourier Transform Software

Frequency Analyzer by Reliable Software

This program splits sound taken from the microphone into basic frequencies and displays them in real-time. Whistle to the microphone and see the plot move up and down with the pitch change. This uses the Fast Fourier Transform (FFT) Transform.
