Music & Effects. The “M” and “E” in DME. A three-track film soundtrack mix, less dialogue, used for foreign voice dubbing. A foreign language film version requires that all sound effects that are otherwise included in the dialog stem are copied across to the effects stem. If these production effects are not clear of dialog, then they must be replaced either by Foley tracks or by cut effects. Once the effects are complete, the track is said to be “filled”, thus contracts specify “music and filled effects.” Also known as the international version, or mufex. See stem, final mix.
