Most of the control parameters of our project are represented as GUI sliders. Until now, we adjusted them only manually using the mouse. In this chapter, we will discover several ways to automate sliders by covering the following topics:
Using time values for a parameter's automation
Using Perlin noise
Playing an audio file, capturing the sound from a sound card, and measuring the sound level
Reading and parsing data from a text file
At the end of the chapter, we will obtain a project that generates animated visuals, reacts on a prerecorded or captured level of sound, and reads a parameter's values from a text file containing neural data recording.
