+# Audio System
+
+Centralised voice-limited audio for the game. Lives in `Assets/_Project/Scripts/Audio/`.
+
+## How it works
+
+`AudioManager` is a per-scene MonoBehaviour singleton. On `Awake` it pre-allocates a pool of `AudioSource` components (on its own GameObject) for each sound category. Callers request playback via `AudioManager.Instance.Play(clip, category, pitch)` — the manager picks the next source in that category's pool using round-robin, interrupting the oldest sound if all voices are busy.
+
+## Categories (`AudioCategory` enum)
+
+| Category | Typical use |
+|---|---|
+| `TowerFire` | Tower attack sounds |
+| `EnemyHitDeath` | Enemy damage and death sounds |
+| `UI` | Button clicks, placement confirmation, etc. |
+| `Music` | Background music |
+
+Voice limits and volume per category are configured in the Inspector on the `AudioManager` scene GameObject.
+
+## Scene setup
+
+An empty GameObject named `AudioManager` must exist in each gameplay scene with the `AudioManager` component attached. Configure the `Categories` array in the Inspector — one entry per `AudioCategory` value.
+
+Suggested defaults:
+- TowerFire: 4 voices, volume 1.0
+- EnemyHitDeath: 8 voices, volume 1.0
+- UI: 4 voices, volume 1.0
+- Music: 2 voices, volume 0.8
+
+## Adding a new sound-emitting component
+
+1. Get a reference to an `AudioClip` via `[SerializeField]`
+2. Call `AudioManager.Instance?.Play(clip, AudioCategory.YourCategory)` at the point the sound should trigger
+3. Pitch randomization (if desired) is the caller's responsibility: `Random.Range(minPitch, maxPitch)` passed as the third argument
+
+See `TeslaTowerFireSound.cs` in `Scripts/Combat/` as a reference implementation.
