Unity supports quite a few common sound formats, including. That's where the sound effect to be played goes. What interests us the most here is the AudioClip slot, however. This includes its pitch, panning, spatial blending (We'll get to that later), and if you open the 3D Sound Settings, you will find options for adding Doppler Effects and volume rolloffs. The Audio Source component has quite a few properties which we can tinker around with.
In common development practice, it's generally a good idea to make an empty gameObject to act as the Audio Source and make it a child when you're dealing with large, complex structures, so you have a clear idea of where the Audio Source is. This is the component that's actually responsible for playing the sound. Leaving the Audio Listener as it is, is recommended. It doesn't have any properties, since its only job is to act as the point of perception. This is a component that's automatically attached to the main camera every time you create a scene. We deal with 2 main components related to Audio in Unity, they are: Getting louder as the player gets closer, making sure the audio panning varies as the relative position of the waterfall changes with respect to the player, and so on. For example, we need to make sure that a gameObject playing the sound of a waterfall matches with an actual waterfall gameObject, and that the player's perception of that sound feels real. In Unity, the positioning of a source of audio is important to characterize its source. Perception of audio generally involves the position of the source and how fast it's moving if it's moving at all (If you've studied Physics, you may be familiar with the Doppler Effect). The way it's perceived depends on a lot of factors, which have to be taken into account when you're trying to control or use it. RigidBody Movement: velocity and AddForce()Īudio is quite an interesting concept to cover, not only in game design but when studying its nature in general.
