# AAS\_AudioSystemInterface

```cpp
class ADVANCEDAUDIOSYSTEM_API IAAS_AudioSystemInterface
```

Interface for the Advanced Audio System (AAS). Provides a foundation for managing and interacting with audio systems, enabling communication between the AudioSubsystem, components, and gameplay related audio-logic. This interface is minimal and can be extended as needed.

**Key Features:**

* Modular design with support for Foley and Weapon audio systems.
* Exposes functionality for retrieving and managing audio banks.
* Facilitates the implementation of audio events, including playback and interaction.
* Blueprint-compatible API for ease of use in Unreal Engine.

**Usage:**

Any actor or component that needs to communicate or integrate with audio-related systems should implement this interface. This could include retrieving audio banks, handling audio playback details, or allowing for subsystem-specific audio interactions.

### **Functions**

```actionscript-3
#pragma region Foley
    UFUNCTION(BlueprintImplementableEvent, Category = "AdvancedAudioSystem|FoleyAudioBank")
    void GetFoleyAudioBank(UAAS_FoleyAudioBankData*& OutAudioBankData);

    UFUNCTION(BlueprintImplementableEvent, BlueprintCallable, Category = "AdvancedAudioSystem|FoleyAudioBank")
    void SetFoleyAudioBank(UAAS_FoleyAudioBankData* InAudioBankData);

    UFUNCTION(BlueprintImplementableEvent, Category = "AdvancedAudioSystem|FoleyAudioBank")
    bool CanPlayFootstepSounds();
#pragma endregion

#pragma region Weapons
    UFUNCTION(BlueprintImplementableEvent, Category = "AdvancedAudioSystem|Weapon")
    bool CanPlayWeaponSounds();

    UFUNCTION(BlueprintNativeEvent, BlueprintCallable, Category = "AdvancedAudioSystem|Weapon")
    void OnWeaponInterrupted();
