The SoundEffectInstance is a copy of a SoundEffect which can be played on its own. Each SoundEffectInstance can only be played once at a time. Therefore if two sounds must overlap, then two SoundEffectInstances are needed. By contrast, calling SoundEffect.Play multiple times will result in overlapping sounds.

Although the SoundEffectInstance requires multiple instances for simultaneous plays, it provides the number of benefits:

  • It can be stopped at any time
  • It provides parameters for modifying how the sound effect is played (such as pitch)
  • You can inspect if a SoundEffectInstance is playing

For information on using SoundEffectInstances in Glue, see the Glue SoundEffectInstance page.

For a more detail on the SoundEffectInstance class, see Microsoft XNA’s SoundEffectInstance reference.
