Audio

Managing Audio With Scriptable Objects

High level overview:

• Using scriptable objects you can use events to play 2D+3D SFX and music without having audio sources start in your scene. Also music will persist between scenes.

• Using scriptable objects you can use UI sliders + events to interface with the audio mixer. This makes setting the volume across multiple groups easy.

Example

Description of Major Components:

• AudioMixerGroupManager.cs

  • A scriptable object

  • Has reference to a audio mixer and the name of an audio group.

  • Use sliders + events to set audio levels + set slider values on start.

• AudioSourceManager.cs

  • A scriptable object

  • Has a pool of 2D audio sources it attaches to the audio listener in a scene

  • Uses object pooling to access 3D audio sources

  • For Music audio it uses a prefab audio source that is a singleton + is not destroyed on load

• SoundAsset.cs

  • A Scriptable object

  • Has a reference to an audio clip, audio mixer group, volume level, and AudioSourceManager

  • When it plays audio it asks for sources from the AudioSourceManager and applies the above settings to the source before playing it.
