Adding sound in Unity is simple enough, but you can implement it better if you understand how sound travels. While this is extremely important in 3D games because of the added third dimension, it is quite important in 2D games, just in a slightly different way. Before we discuss the differences, let's first learn about what and how sound works from a quick physics lesson.
Basics of audio and sound FX in Unity
Listening to the physics behind sound
What we hear is not just music, sound effects (FX) and ambient background noise. The sound is a longitudinal, mechanical (vibrating) wave. These "waves" can pass through different mediums (for example, air, water, your desk) but not through a vacuum. Therefore, no...
