## Key takeaways
- The Effects Rack holds 1,459 effects in 16 collections and applies a chain of up to eight slots to the whole mix or to any single stem.
- Sound flows top to bottom through the chain; each slot has bypass, parameters, reordering and a 0 to 100% dry/wet Mix.
- Research collections draw on Haas, Chowning, Blauert, Karplus-Strong, Peterson and Barney, Roads, Schroeder, Moorer, Dattorro, Zwicker and ISO 226.
- The Preview player compares Dry (A) and Effect (B) on a stem, the mix or a beep, and effects are included in exports by default.

In this lesson: You will learn how the classroom Effects Rack works, from the 8-slot chain to dry/wet mix and bypass, and tour its 16 collections, including 7.1.4 reverbs, NASA sonifications and effects built on decades of audio research. You will also learn how to preview an effect safely before it touches your mix.

Effects shape character. A reverb tells the listener what room they are in. A delay adds rhythm and depth. A granular cloud turns a note into weather. In immersive audio, effects also shape space itself: a reverb can fill the ceiling, and a psychoacoustic trick can make a sound seem wider than its position.

The classroom Effects Rack holds 1,459 effects in 16 collections. That is a lot, so this lesson gives you a map, the science behind the most interesting collections, and a safe way to try things.
