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)

Calc 3D is a collection of mathematical tools for highschool and university. The calculator can do statistics, best fits, function plotting, integration. It handles vectors, matrices, complex numbers, coordinates, regular polygons and intersections. For objects ( like point, line, plane and sphere) distances and intersections are calculated. Cartesian, spherical and cylindrical coordinates can be transformed into each other.

cross prod, division, complex, vectors, matrix, statistic, subtraction, quaternion, intersection, scalar product, polygon, spat product
