In this chapter, we considered several sources of data to animate parameters of the project. At first, we implemented time-dependent LFO and Perlin noise. Then, we explored how to play and capture sounds and measure the level of sound using RMS measure. Finally, you learned to read lines from a text file, parse them, and use them for a parameter's automation.

The data sources we explored can be named built-in sources, because they rely on capabilities that are built into the computer itself. In the next chapter, we will study using external data sources, such as controlling the project by networking and connecting new peripheral devices using the Arduino board.
