Adding audio to your experiences is crucial for elevating your experiences to new heights. By strategically using positional and non-positional audio, you can immerse players into your worlds, provide them useful feedback for their actions, and direct their attention to what they need to do to be successful in their objectives.
Audio assets
You can import audio assets that you're certain you have permission to use, such as audio that you make yourself. However, Roblox's Creator Store provides you a wide variety of free-to-use audio assets, including more than 100,000 professionally-produced sound effects and music tracks from top audio and music partners.
Audio objects
Roblox offers many different types of audio objects that you can use to play and modify your audio until it meets your experience's design requirements:
- The AudioEmitter object is a virtual speaker that emits audio into the 3D environment.
- The AudioListener object is a virtual microphone that picks up audio from the 3D environment.
- The AudioDeviceOutput object is a physical hardware device within the real world, such as a speaker or headphones.
- The AudioDeviceInput object is a physical microphone within the real world.
- Wires carry audio streams from one object to another.
Using these objects, you can either set audio to play automatically at runtime, or trigger it to play from scripts. For practical applications of these audio objects, see the Add 2D audio, Add 3D audio, and Add voice chat tutorials.
Audio effects
Audio effects non-destructively modify or enhance audio streams from AudioPlayer objects. You can apply these effects to make your environments more captivating and immersive, such as using a AudioEqualizer object to make rain sound muffled, AudioCompressor object to control a sound's maximum volume, or AudioReverb to add more realistic reflections of sound in interior spaces.
