Translation of "ជំនួយឧបករណ៏បំពងសំលេង" into English

A System Audio Effects (SYSFX) component used to provide a more immersive audio experience in the Windows Media Player and thus an improved listening experience by utilizing the available speakers that a user has attached to his/her PC by sending audio to all of the speakers, regardless of the number of channels the content contains. This will provide a better sounding experience for stereo and quadraphonic content being rendered on multi-channel playback systems.
