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. 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)
