Unreal sound formats and terminologies

There are a couple of terms in the Unreal Sound system that we need to get acquainted with:

• Sound waves: These are the actual audio files that are in the .wav format.

• Sound cues: This is the control system for a sound wave file. Sound cues are what we use to manipulate the volume, start, and end of the sound waves. So, in order to control how an audio file is played in the game, you can edit the properties on the Sound Cue, which, in turn, affects the wave file or files that it is associated with.

• Ambient Sound Actor: This is the class actor that you add to the game level. This actor is associated with the Sound Cue to play the audio files that you need for the game.

Now, we are ready to use the Sound Editor in Unreal.
