Product Details

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

Requirements: microphone; soundcard
Release Info: New Release on Feb 07, 2004
Release Notes: improved GUI; plus you can play and analyze .wav files
