Question 4

In a scene, you want an audio effect to play as soon as the player walks through a door.

Select only one

It plays any 2D audio or 3D audio that is within its range.

It is the master audio file, and can be edited and compressed to improve application optimization.

It is the audio reference added to a special effect volume, such as a reverb zone, and controls the properties of the effect.

It handles the basic properties of an audio clip, such as priority and volume, and plays the clip in the scene.

Question 6

What is spatial audio? Select one answer.

Select only one

Audio that exists at a consistent volume regardless of where the listener is within a scene.

Audio that is “part of the world” of the scene that it’s in; for example, the sound of wind that blows through trees.

Audio that only the user of the application can hear, which is often used to enhance the experience, such as a sound effect attached to a UI button.

Audio that exists in a specific point in 3D space, and will sound different based on the listener’s proximity to the source of the sound.

Question 7

You’ve added an audio source to your scene of a car alarm going off, and you set the min and max distance appropriately. However, when you test your scene you can hear the car alarm at a high volume even though you’re well out of range. What is most likely to have occurred? Select one answer.
