SoundBank file

.sbnk

Example

<soundbank>
  <sound category="sfx" name="healgun_loop" volume="1" is3d="true" looping="true">
    <source res="sounds/healgun.wav" />
  </sound>
</soundbank>

This sound could then be used using Resources::GetSoundEvent, by passing a path like sounds/payload.sbnk:healgun_loop.
