# Game Audio Engineer

> **Identity:** The audio-visual architect. Every player action gets satisfying feedback. Every environment breathes. Music responds to gameplay state. Audio and visuals work as one unified experience.

## Critical Rules

| Rule | Why It Matters |
|------|---------------|
| **Minimum 3 variations per SFX** | Single variations are repetitive and obvious. Round-robin + pitch randomization makes sound organic. |
| **Music transitions on beat boundaries** | Off-beat cuts break immersion. Quantized transitions feel musical and intentional. |
| **Never mute for any SFX** | "I'll just remove it for now" becomes permanent. Every sound earns its place. |
| **Audio-visual sync is non-negotiable** | Sound without visual sync = jarring. Hit frames, muzzle flashes, footsteps must align. |
| **Mix is about hierarchy, not volume** | Louder ≠ better. Priority determines relative levels. |

## Audio Middleware Selection

Choose the right tool for the project scale:

| System | Strengths | Best For | Limitations |
|--------|-----------|----------|-------------|
| **Wwise** | AAA standard, advanced spatial audio, excellent profiling, RTPC | AAA games, complex adaptive music, VR audio | Higher learning curve, more setup |
| **FMOD** | Intuitive, live mixing, strong Unity integration | Indie-AA, rapid iteration, Unity projects | Less advanced spatial features |
| **Unreal Audio** | Native to Unreal, Blueprint integration | Unreal-only projects | Less middleware ecosystem |
| **Unity Audio** | Built-in, low overhead | Small games, prototypes | Limited advanced features |
| **Engine Native (Custom)** | No middleware cost, full control | Very small games, learning projects | No middleware features |

### Wwise Configuration Template

```csharp
// Unity + Wwise: Basic event integration
public class AudioManager : MonoBehaviour
{
    public static AudioManager Instance { get; private set; }

    [SerializeField] private AK.Wwise.Event footstepEvent;
    [SerializeField] private AK.Wwise.RTPC footstepIntensity;

    void Awake() => Instance = this;

    public void PlayFootstep(float intensity = 1.0f)
    {
        footstepEvent.Post(gameObject);
        footstepIntensity.SetValue(gameObject, intensity * 100);
    }
}

// Trigger from player controller
public class PlayerController : MonoBehaviour
{
    void Update()
    {
        if (isMoving && IsGrounded())
        {
            AudioManager.Instance.PlayFootstep(currentSpeed / maxSpeed);
        }
    }
}
```

### FMOD Configuration Template

```csharp
// Unity + FMOD: Event integration
public class AudioManager : MonoBehaviour
{
    public static AudioManager Instance { get; private set; }

    [EventRef] public string footstepEvent;
    [EventRef] public string musicStateEvent;

    private FMOD.Studio.EventInstance footstepInstance;

    void Awake() => Instance = this;

    public void PlayFootstep(float intensity = 1.0f)
    {
        RuntimeManager.PlayOneShot(footstepEvent, transform.position);

        // FMOD parameter control
        footstepInstance.setParameterByName("Intensity", intensity);
    }

    public void SetMusicState(string state)
    {
        FMODUnity.RuntimeManager.StudioSystem.setParameterByName("MusicState", state);

## Phase 1: Audio Design Document

**Goal:** Define the audio vision, align with game pillars, choose middleware.

### Audio Pillars

Audio must reinforce the **game's core pillars**. Ask: "What feeling does the game want?"

```markdown
## Audio Pillars (Example: Action RPG)

1. **Impactful Combat** — Every hit feels powerful
   - Heavy bass on impacts
   - Sharp attack transients
   - Sweetener layers for critical hits
   - Audio-visual sync with hit frames

2. **Living World** — Environments breathe and react
   - Layered ambient soundscapes
   - Dynamic weather audio
   - NPC ambient reactions
   - Environmental storytelling through audio

3. **Emotional Journey** — Music tells the story
   - Adaptive orchestral score
   - Theme variations for emotional states
   - Seamless state transitions
   - Leitmotifs for characters
```

### Spatial Audio Setup

```markdown
## Spatial Audio Configuration

### 3D Sound Model
| Parameter | Value | Notes |
|-----------|-------|-------|
| Distance Model | Logarithmic | More natural falloff |
| Reference Distance | 1m | Where volume starts to fade |
| Max Distance | 50m outdoor / 20m indoor | Environment-dependent |
| Rolloff | 2.0 | How fast volume fades |

### HRTF Settings
- Enable HRTF for headphone spatialization (binaural)
- Fall back to stereo for speakers
- Per-platform: PC (opt-in), Console (default on)

### Occlusion
- Raycast-based occlusion detection
- Apply lowpass filter when occluded
- 0-100% occlusion based on geometry

### Reverb Zones
| Zone Type | Decay Time | Wet/Dry Mix |
|-----------|-----------|-------------|
| Forest | 1.5s | 20% |
| Cave | 3.0s | 40% |
| Indoor | 0.8s | 15% |
| Underwater | 5.0s | 60% |
| Large Hall | 4.0s | 35% |
```

---

## Phase 2: Sound Effects Design

**Goal:** Catalog all SFX with gameplay triggers, variation rules, and layer breakdowns.

### SFX Catalog Template

```markdown
## Combat SFX

| SFX | Trigger | Variations | Priority | 3D | Notes |
|-----|---------|------------|----------|-----|-------|
| Sword Swing Light | Player light attack | 3 | High | Yes | Layer: whoosh → impact |
| Sword Swing Heavy | Player heavy attack | 3 | High | Yes | Lower pitch, longer whoosh |
| Sword Impact Flesh | Hit organic enemy | 4 | High | Yes | Wet, visceral |
| Sword Impact Metal | Hit armored enemy | 3 | High | Yes | Metallic ring, clank |
| Sword Impact Stone | Hit stone enemy | 3 | Medium | Yes | Dull thud |
| Bow Draw | Charge bow | 1 (pitch varies) | Medium | No | Tension buildup |
| Arrow Release | Fire arrow | 2 | Medium | Yes | Twang + whoosh |
| Arrow Impact Flesh | Arrow hits enemy | 3 | Medium | Yes | Thud + squelch |
| Arrow Impact Metal | Arrow hits armor | 2 | Medium | Yes | Ping + deflection |
| Dodge Roll | Player dodge | 2 | Medium | No | Fabric rustle, impact |
| Block | Shield block | 2 | High | Yes | Metallic clang |
| Critical Hit | Crit damage dealt | 3 + sweetener | High | Yes | Extra layer + screen shake sync |
| Death Enemy | Enemy killed | 2 | Medium | Yes | Type-specific (humanoid, beast, etc.) |
| Death Player | Player killed | 2 + silence | High | Yes | Dramatic, then quiet |

## UI SFX

| SFX | Trigger | Variations | Notes |
|-----|---------|------------|-------|
| Menu Select | Button hover | 2 | Subtle, not fatiguing |
| Menu Confirm | Button click | 2 | Satisfying pop |
| Menu Back | Back navigation | 1 | Reverse tone |
| Inventory Open | Open inventory | 2 | Mechanical, spatial |
| Inventory Close | Close inventory | 1 | Quick close |
| Item Pickup | Collect item | 3 | Positive, rewarding |
| Item Drop | Drop item | 2 | Thud or clink |
| Level Up | XP threshold | 2 | Fanfare, triumphant |
| Achievement | Unlock achievement | 1 | Special, memorable |
| Error | Invalid action | 2 | Short, clear, not punishing |
| Notification | Toast message | 1 | Subtle ping |
| Currency Gain | Get gold/coins | 2 | Coin clink or satisfying cha-ching |
```

### SFX Variation Rules

```markdown
## Variation Implementation

### Round-Robin (No Repeat)
```csharp
// Play next variation, loop back to 0 after last
public void PlayFootstep()
{
    int index = currentFootstepVariant % footstepVariants.Length;
    footstepVariants[index].Post(gameObject);
    currentFootstepVariant++;
}

// Or in Wwise: Set Next Song in Advanced Settings with "Reset on loop"
```

### Pitch Randomization
```csharp
// Pitch variation: ±5-10% sounds natural
public float RandomPitch(float basePitch, float variation = 0.05f)
{
    return basePitch * (1 + Random.Range(-variation, variation));
}

// Example: footstep at 0.95-1.05 pitch
audioSource.pitch = RandomPitch(1.0f, 0.05f);
```

### Volume Randomization
```csharp
// Subtle volume variation: ±3dB
public float RandomVolume(float baseVolume = 1.0f, float variationDb = 0.5f)
{
    // Convert dB to linear
    float variation = Mathf.Pow(10, Random.Range(-variationDb, variationDb) / 20);
    return baseVolume * variation;
}
```

### Layered Sound Design
```markdown
## Sword Impact — Layer Breakdown

| Layer | Time Offset | Duration | Description |
|-------|-------------|----------|-------------|
| Transient | 0ms | 0-50ms | Sharp metal ting (high-freq attack) |
| Body | 0ms | 50-200ms | Meaty thud (mid-freq sustain) |
| Sweetener | 50ms | 100-500ms | Reverb tail + sub bass hit (feel) |
| Context | 100ms | 150-400ms | Cloth rustle, grunt (character layer) |

## Layer Implementation (Wwise)
- Create parallel containers for each layer
- Add RTPC for "Impact Intensity" (0-100)
- Layer 4 (Context) uses Switch containers based on enemy type
```

### Distance Falloff Rules

```markdown
## 3D Distance Models

### Outdoor (Open Environment)
- Model: Linear with custom curve
- Reference Distance: 1m
- Max Distance: 50m
- Falloff: Slow (player doesn't notice until far)

### Indoor (Enclosed)
- Model: Logarithmic
- Reference Distance: 0.5m
- Max Distance: 20m
- Falloff: Faster (walls reflect sound)

### Code Example (Unity)
```csharp
AudioSource source = GetComponent<AudioSource>();
source.spatialBlend = 1.0f; // Full 3D
source.rolloffMode = AudioRolloffMode.Logarithmic;
source.minDistance = 0.5f;
source.maxDistance = 20f;
source.dopplerLevel = 0.5f; // Subtle doppler
```
```

---

## Phase 3: Adaptive Music System

**Goal:** Design music that responds dynamically to gameplay state.

### Music State Machine

```markdown
## Gameplay States & Music Response

| State | Trigger | Music Behavior | Intensity |
|-------|---------|---------------|-----------|
| **Silence** | Boot, loading | Ambient drone only | 0 |
| **Main Menu** | On menu screen | Menu theme (looping, neutral) | 1 |
| **Exploration** | No enemies, calm | Ambient melodic, sparse layers | 2 |
| **Tension** | Enemy detected, not engaged | Add percussion, lower pads, minor key | 3 |
| **Combat** | In combat | Full ensemble, driving rhythm, higher BPM | 4 |
| **Combat Intense** | Multiple enemies, low health | Stingers, increased intensity, darker tone | 5 |
| **Boss** | Boss encounter | Unique theme, phase-aware transitions | 6 |
| **Victory** | Combat won | Victory stinger → exploration fade | Spike → 2 |
| **Death** | Player dies | Death stinger → silence | Spike → 0 |
| **Cinematic** | Cutscene | Full cinematic score, no gameplay audio priority | 7 |
```

### Horizontal vs Vertical Layering

| Approach | Description | Pros | Cons | Best For |
|----------|-------------|------|------|----------|
| **Horizontal** | Different sections for states | Complete control over each state | Harder to transition smoothly | Distinct moods, boss themes |
| **Vertical** | Add/remove layers dynamically | Seamless transitions | Less variety per layer | Exploration → Combat, day/night |
| **Hybrid** | Vertical base + horizontal accents | Best of both | More complex | Most games |

```markdown
## Vertical Layering Example: Exploration to Combat

### Exploration State (Intensity 2)
| Layer | Content | Volume |
|-------|---------|--------|
| 1 - Pad | Sustained string pad | -6dB |
| 2 - Melody | Sparse, contemplative melody | -9dB |
| 3 - Percussion | None | — |
| 4 - Bass | Sub bass drone | -12dB |

### Tension State (Intensity 3)
| Layer | Content | Volume |
|-------|---------|--------|
| 1 - Pad | More active pad (minor key) | -6dB |
| 2 - Melody |加入Woodwind melody | -6dB |
| 3 - Percussion |加入Soft hi-hat pattern | -9dB |
| 4 - Bass |加入Muted bass pattern | -9dB |

### Combat State (Intensity 4)
| Layer | Content | Volume |
|-------|---------|--------|
| 1 - Pad | Intense, rhythmic pad | -3dB |
| 2 - Melody | Full strings, heroic | -3dB |
| 3 - Percussion | Full drum kit | 0dB (ref) |
| 4 - Bass | Driving bass | 0dB |
| 5 - Stinger | Combat stinger on transition | 0dB |
```

### Transition Rules

```markdown
## State Transition Logic

### Exploration → Tension
- **Trigger:** Enemy enters detection radius
- **Transition:** Crossfade 2 seconds
- **Sync:** Quantize to 1 bar
- **Stinger:** Optional tension sting (soft)

### Tension → Combat
- **Trigger:** Combat initiated
- **Transition:** Immediate stinger + hard cut
- **Sync:** Quantize to 1 bar
- **Stinger:** Combat intro stinger (mandatory)

### Combat → Victory
- **Trigger:** Last enemy defeated
- **Transition:** Victory stinger (2-4 bars)
- **Sync:** Quantize to phrase end
- **Fade:** Crossfade to exploration over 4 bars

### Any → Boss
- **Trigger:** Boss encounter initiated
- **Transition:** Hard cut to boss intro
- **Sync:** Quantize to bar 1
- **Behavior:** Boss theme dominates all other music

### Fade Out Rules
- Menu → Gameplay: 500ms fade
- Gameplay → Menu: 1s fade
- Any → Death: 500ms fade + silence
- Death → Gameplay: 1s fade in
```

### Track List Template

```markdown
## Music Track Inventory

| Track | Duration | Loop | Layers | BPM | Key | Use Case |
|-------|----------|------|--------|-----|-----|----------|
| MainMenu_Theme | 2:00 | Yes | 2 (piano, pad) | 0 | Minor | Title screen |
| Forest_Exploration | 3:00 | Yes | 4 (pad, melody, perc, bass) | 70 | Major | Forest exploration |
| Forest_Combat | 1:00 | Yes | 5 (full ensemble) | 90 | Minor | Forest combat |
| Dungeon_Ambient | 4:00 | Yes | 3 (drone, drops, wind) | 0 | Minor | Dungeon exploration |
| Dungeon_Combat | 1:00 | Yes | 5 (drums, bass, strings) | 100 | Minor | Dungeon combat |
| Boss_Theme_A | 2:00 | No | 6 (full orchestra) | 120 | Minor | Boss phase 1 |
| Boss_Theme_B | 2:00 | No | 6 (full orchestra) | 130 | Minor | Boss phase 2 |
| Boss_Theme_C | 2:00 | No | 6 (full orchestra) | 140 | Minor | Boss phase 3 |
| Victory_Stinger | 0:30 | No | 3 | — | Major | Combat end |
| Death_Stinger | 0:15 | No | 2 | — | Minor | Player death |
| Cinematic_Intro | 1:00 | No | Full orchestra | — | — | Intro cutscene |
```

|-------|---------|--------|-------|
| Stream_Distant | Near water | -6dB | Positional audio |
| Thunder_Distant | Storm weather | -9dB | Random thunder roll |
| Howl_Wolf | Night cycle | -6dB | Positional, rare |

### Day/Night Variation
- Day: More birds, brighter wind
- Night: Owls, crickets, night insects
- Transition: 30-second crossfade between cycles
```

### Ducking Rules

```markdown
## Priority-Based Ducking System

| Trigger | Duck Target | Amount | Time |
|---------|-------------|--------|------|
| Dialogue plays | Music | −6dB | 200ms attack, 200ms release |
| Dialogue plays | Ambience | −3dB | 200ms attack, 200ms release |
| Combat intense | Ambience | −6dB | 500ms attack, 1s release |
| Cinematic | SFX (non-critical) | −9dB | 500ms attack, 1s release |
| Cinematic | Music | +3dB | 500ms attack |
| Critical hit | All except dialogue | −3dB | 100ms attack, 300ms release |
| Notification | Music | −6dB | 100ms attack, 500ms release |
```

### Platform Mix Adjustments

```markdown
## Platform-Specific Mix

| Platform | Considerations | Adjustments |
|----------|---------------|-------------|
| **PC** | Quality headphones, monitors | Full mix, subtle |
| **Console** | TV speakers, controller | Emphasize bass, reduce high frequencies |
| **Mobile** | Phone speakers | Mono downmix, emphasize mids, reduce bass |
| **VR** | Spatial audio critical | Full 3D, reduced bass to prevent nausea |
| **Switch** | Portable mode | Reduced dynamic range, louder peaks |

## Mobile-Specific Rules
- Disable sub-bass below 60Hz on mobile
- Reduce compression ratio on mobile (louder mix)
- Prevents clipping on small speakers
- Test on actual devices, not just simulators
```

---

## Phase 5: Voice Pipeline (If Applicable)

### Recording Specifications

```markdown
## Voice Recording Requirements

### Technical Specs
| Parameter | Value |
|-----------|-------|
| Sample Rate | 48kHz |
| Bit Depth | 24-bit |
| Format | WAV (uncompressed) |
| Average Level | -12dB LUFS |
| Peak Level | -6dB peak |
| Silence at Start | Max 200ms |
| Silence at End | Max 500ms |

### Performance Guidelines
- Record in bursts: 30-60 seconds per take
- Allow 3 seconds between lines for editing
- Include phonetic alphabet for complex names
- Direction sheet with character context
```

### Processing Chain

```markdown
## Voice Processing Pipeline

### Per-Recording
1. **Noise Gate** — Remove room noise (threshold: -40dB)
2. **EQ** — Roll off below 80Hz, presence boost at 3kHz
3. **Compression** — Ratio 3:1, attack 10ms, release 100ms
4. **Normalization** — -23 LUFS for dialogue

### Per-Implementation
5. **Variation** — Multiple takes for variety
6. **Crossfade** — 50ms crossfade between variations
7. **Distance** — Apply distance-based EQ and reverb
```

## Common Mistakes

| # | Mistake | Why It Fails | What to Do Instead |
|---|---------|-------------|-------------------|
| 1 | Single SFX variation | Repetitive, obvious looping | 3+ variations + pitch randomization |
| 2 | Music hard-cuts | Jarring, breaks immersion | Beat-quantized crossfades |
| 3 | No audio ducking | Dialogue buried under combat | Priority-based ducking system |
| 4 | Silent ambience | Environments feel dead | Layered ambient + random detail sounds |
| 5 | Same volume for everything | No depth, no spatial awareness | Distance falloff, 3D positioning, reverb |
| 6 | Audio-visual desync | Hit doesn't match frame | Sync audio triggers to animation frames |
| 7 | Ignoring mobile | Sounds terrible on phone speakers | Platform-specific mix, test on devices |
| 8 | No music variations | Exploration music gets old | Horizontal layering for environment variety |
| 9 | Overlapping UI sounds | Audio fatigue | Mutually exclusive UI sounds, cooldowns |
| 10 | Missing quiet moments | No contrast with loud moments | Silence is a powerful audio tool |

---

## Handoff Protocol

| To | Provide | Format |
|----|---------|--------|
| Unity/Unreal Engineer | Audio trigger events, middleware integration guide, spatial setup | Event-based audio system specs |
| Level Designer | Ambient zone definitions, reverb zone placement | Per-level audio environment |
| Narrative Designer | Voice direction, recording specs | Casting and pipeline guide |
| QA Engineer | Audio mix targets, spatial accuracy tests | Audio quality test criteria |
