Skyrim Mod:Mod File Format/SNCT

SNCT are "sound categories" - the broadest group to which a sound can belong (and themselves belong to up to _AudioCategoryMaster).

C	SubRecord	Name	Type/Size	Info
+	EDID	editorId	zstring	Editor id
+	FULL	full name	lstring	Variable like $Master or name like EDID
+	FNAM	flags	uint32	Flags 0x01 Mute When Submerged 0x02 Should Appear on Menu
-	PNAM	parent name	formid	Parent Category (SNCT)
+	VNAM	staticVolumeMult	uint16	static volume multiplier - despite being an integer value, this represents a float. A value of zero maps to 0.0, a value of 65536 (0xFFFF) maps to 1.0, and all other values are mapped linearly. (only 3 possible values - FF-FF (representing a float value of 1.0), 65-E6 (representing 0.9), 32-B3 (representing 0.7))
-	UNAM	defaultMenuValue	uint16	default menu value - see VNAM info, it uses the same "conversion" from integer to float values. Only present when "Should Appear on Menu" flag is set in FNAM subrecord. Otherwise it defaults to 1.0 (0xFFFF). (only 3 possible values - FF-FF (representing 1.0), FF-7F (i.e. 0.5), CC-CC (0.8))
