USoundClass
#include "Sound/SoundClass.h" Description
A hierarchical category asset that groups sounds and applies shared volume, pitch, reverb, and submix routing. SoundMixes target SoundClasses to bulk-adjust multiple sounds simultaneously.
Caveats & Gotchas
- • SoundClass Properties (volume, pitch) are not modifiable at runtime directly — use SoundMix to push and pop temporary adjustments.
- • Properties cascade to child SoundClasses multiplicatively. A volume change on a parent multiplies through all descendants, which can produce unexpected results in deep hierarchies.
- • LoadingBehavior on a SoundClass propagates to all member SoundWaves that don't have their own override. Changing it can have a significant impact on memory usage.
Example
Assign a SoundClass to a SoundBase C++
// Set in the asset editor, or at runtime:
MySoundWave->SoundClassObject = MusicSoundClass;See Also
