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
