Game which integrates prerecorded & synthesized audio effects and area-aware music into the Unity audio system by providing reusable components. Made as coursework for a module in University.
- W, A, S, D - Walk around.
- Mouse - Look around
- Left Mouse Button - Interact
- Alt + F4 - Exit
- Bed: Changes outside sound and plays snore sound.
- Drink glasses: Add/clear sound effects.
- Cooker: Knob and oven sound.
- Moving between inside and outside: Indoor the outside effects are muffled and different music tracks are paused/played.
- Fridge: Plays sounds randomly.
- Footsteps: Grass, wood, and path.
Only open in Unity 2020.1.x as 2020.2.x breaks the audio mixers and general audio playback.
The game aimed to integrate with the Unity audio system as possible. For that reason it uses the Audio Source/Audio Listener components to emit/'listen' to audio. Audio Mixers are used to separate the different sounds into easily modifiable groups, on which Audio Snapshots (namely low/high pass, delay, pitch shift) are applied depending on the location of the player (inside/outside) and whether they are intoxicated (in which case a high pitched noise simulating tinnitus is procedurally generated inside the overriddenOnBufferRead() method).
In addition, the project attempts to create reusable and easy to integrate into the project using the editor.
For a more aesthetically pleasing rundown of these features, please see the presentation.
Depending on which audio zone the player is located in (which is changed by a trigger collider), the outdoor music is then cross faded with the indoor one. The outgoing loop is 'paused' (position in playback kept) then resumed when played again.
The OnBufferRead() method is used to generate the high pitched noise. This involves generating a sine wave and copying it across the dual audio channels (which are interweaved). Control of the sound is done via atomics (simple data types in C# are atomic by default).
Some sound effects (oven sound, cooker & oven knobs) were recorded by me. All the sound effects were then processed using Audacity, where they were:
- Trimmed to size (with care taken to make sure the start/end of clip is crossing at zero to avoid pops).
- Normalized to integrate with spatial audio better.
- Faded in/out where applicable.
The oven sound also has a noise reduction profile reduced due to background noise at high gain levels.
The project was largely coded by me using the HDRP template. The icon was sourced from Google Material Icons under Apache 2.0. The character movement code was sourced from here
