3. Apple iOS Apps
These Apple apps are available on the Apple store and run on iPhone/iPad.
Filter Creator helps you to better understand the mathematics of discrete and continuous audio filters and is particularly aimed at students of signal processing classes.
This app generates artistic representations of Mondrian processes. These processes are named after Piet Mondrian (1872-1944), a great figure in the neoplasticism style known for his grid-based paintings.
