Overview

What is Frequency Analyzer?

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.

In depth

A closer look at Frequency Analyzer

Whistle a melody and watch this program graph the pitch in real time. The Frequency Analyzer technically speaking performs a Fast Fourier Transform of the sound (you need a sound card and a microphone to use this program). What it means is that it analyzes your voice and splits it into its component frequencies. Watch patterns of speech, the harmonics of vowels and the noise of sibilants. The size of the program is only 64k! (zipped 32k) Can you believe that?! There are web pages that make you download more than that just to be able to look at them
