“Sound is half of the picture.”

– G. Lucas

With this key area of my portfolio, I bring Best Practices and Optimization techniques.

Audio

Unity’s audio features include full 3D spatial sound, real-time mixing and mastering, hierarchies of mixers, snapshots, and predefined effects.

Unity Concepts

  • AudioSource – Plays sounds in a scene
  • AudioListener – Captures audio
  • AudioClip – Represents sound files in Unity
  • AudioMixer – Manages routing and effects
  • AudioMixerGroup – Organizes sounds
  • AudioReverbZone – Simulates reverberation
  • AudioEffect – Applies reverb / echo
  • AudioFilter – Dynamically cut out frequencies

🔔Update: Audio For Unity 6

The latest release of Unity 6 brings key features to first-party support.

RMC Audio Package & Project Template

With Unity, the AudioSource plays back an AudioClip in the Scene.

Setting this up Unity audio from scratch is indeed straightforward. However, organizing your C# audio scripting in a scalable way is non-trivial.

The RMC AudioManager represents a great solution. Its freely available in the RMC Core package and ready for use in your next project.

Check it out!

Features

  • AudioManager Prefab
  • Singleton Access
  • Flexible API
  • Easy to learn
  • Easy to use
  • Hard to misuse

The following steps are completed for you in the sample project.

Audio Manager Usage

  1. Import the RMC Core Unity Package
  2. Drag AudioManager.prefab from /Packages/ to /Assets/
  3. Create configuration via Unity ➜ Assets ➜ Create ➜ RMC ➜ Core ➜ AudioConfiguration
  4. Populate configuration with AudioClips and AudioMixer
  5. Call AudioManager.Instance.PlayAudioClip("SomeAudioClipName");

Audio Manager API

In this sample snippet, the AudioManager (ScriptReference) is plays an audio clip as the player jumps.

No additional C# setup is required for Audio. It just works 🙂

Beyond Unity Audio

Audio Middleware: Why would I want it in my game?

While Unity’s built-in audio system is robust, there are specialized tools that offer additional functionality beyond Unity’s capabilities for advanced use-cases.

  • Wwise – Professional audio middleware used for complex sound design and interactive audio
  • FMOD – Cross-platform audio engine with real-time effects and live mixing capabilities
  • CRIWARE – A versatile solution for high-quality audio in games and interactive media
