A guide for adding and organizing sound in Unity games. It covers music, sound effects, 3D positional audio, volume mixing, and the code patterns that trigger sounds.

Use it to design an audio manager, organize mixer groups, trigger sounds through events, crossfade music, configure 3D sound, and reuse audio sources for frequent effects.

It helps prevent audio logic from being spread throughout gameplay code and makes large numbers of repeated sounds easier to manage. It also helps keep music, effects, and interface sounds separately controllable.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00030	$0.05968
Opus 5	$0.00015	$0.02984
Sonnet 5	$0.00006	$0.01194
Haiku 4.5	$0.00003	$0.00597

Security

Grade A, and why

unity-audio scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 733 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Unity Audio Systems

Guidance for architecting audio in Unity 6: centralized vs distributed approaches, AudioMixer group hierarchies, ScriptableObject-driven event audio, spatial audio configuration, music crossfading, and sound pooling for high-frequency effects.

When to Apply

Activate when the conversation involves:

Adding a first audio system to a project (what architecture to start with)
Deciding how SFX should be triggered from gameplay code (direct call vs event channel)
Setting up AudioMixer groups, snapshots, or send/receive effects
Implementing music that transitions between tracks or layers adaptively
Configuring 3D spatial audio: rolloff curves, reverb zones, occlusion
Pooling audio sources for rapid-fire sounds (gunshots, footsteps)
Mixing and volume control including accessibility (separate sliders for Music/SFX/UI)

Do NOT activate for visual effects triggered alongside audio, animation state that happens to play a sound, or UI layout for volume sliders — those go to hades:unity-vfx, hades:component-design, or hades:unity-ui.

Project Context Check

Before making recommendations:

Check existing audio usage in the graph:
- Call graph_query(edgeKind: "references", edgeTargetNamePattern: "AudioSource", edgeTargetKind: "Class") — count how many objects carry AudioSource directly; if many, the project likely uses a distributed model
- Call search_by_name("*Mixer*") — detect whether an AudioMixer asset already exists; if so, match its group structure
- Call search_by_name("*Audio*") — find existing audio managers, event assets, and listener scripts
Check team decisions in memory:
- Call recall_memory("audio architecture mixer") to surface documented audio decisions or constraints
- Check validation status — if a recalled decision shows warning, surface the conflict before proceeding
Adapt recommendations based on findings:
- If no AudioMixer exists → recommend creating one as a first step before wiring any volume controls
- If the project already uses SO event channels elsewhere → favour SO audio events for consistency
- If distributed AudioSources are pervasive and team is happy with them → recommend adding a mixer and pool rather than a full rewrite
- After the user agrees on an approach not yet documented, call propose_memory_update to record it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

unity-audio is a skill published in the GitHub repository TheArcForge/Hades (27 stars, last pushed 6d ago), licensed MIT. It adds 30 tokens to every session and 5,968 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
