Beats - Superposition of two sound waves.
| Download Beats desktop application (Windows 64bit) | Download Beats source code (Lazarus/Free Pascal) |
Description: Physics application concerning the superposition of two sound waves, showing the phenomena of beats, that occurs when the two
waves have similar but not identical frequencies. The application includes two features: 1. Drawing of the wave curves for two user given frequencies. 2. An animation,
that draws the wave curves for one static and one varying frequency.
Free Pascal features: Mathematical function drawing using bitmap canvas. Positioning of several individual curves on the same drawing surface.
Using a timer to animate curve drawings with variable parameter.
