 +====== .Met ======
 +//Only documenting .Met files as they control .lug audio banks.// \\ 
 +//.Met are usually 2 sections (Audio Information,​ Environment Settings) Ingame.Met contains a third section that links audio to compiled events.// \\ 
  
 +
 +
 +===== Header =====
 +[4] Bytes - Always (01 00 00 00) \\ 
 +[4] Bytes - Number of Files \\ 
 +[4] Bytes - Unknown \\ 
 +
 +
 +==== Audio Information Listing ====
 +[4] Bytes - Entry Number \\ 
 +[4] Bytes - ID \\ 
 +[4] Bytes - Import Directory File Name Length (String Size) \\ 
 +~ String \\ 
 +[4] Bytes - Audio File Size (Does not have header like .Lut audio files) \\ 
 +[4] Bytes - Offset \\ 
 +[2] Bytes - Number of Channels \\ 
 +[2] Bytes - Audio Codec (105 = Xb-Adpcm, 1 = PCM) Only two used.  \\ 
 +[4] Bytes - Frequency \\ 
 +[8] Bytes - Event ID, mostly unused ​ \\ 
 +
 +==== Environment Audio Listing ====
 +Few pieces are unknown! (Hard to test some of these) \\ 
 +=== Header for Environment Audio ===
 +[4] Bytes - Number of Files \\ 
 +
 +=== Audio Listing Loop ===
 +//48 Bytes per listing. Loop until file number is met.// \\ 
 + ​\\ ​
 +[4] Bytes - File Counter \\ 
 +[4] Bytes - File ID \\ 
 +[4] Bytes - String Size for Group Listing (If zero, then string does not exist) \\ 
 +~ String (If it exists) \\ 
 +[2] Bytes - Event Identifier (01 = Day Sound, 02 = Night Sound, 00 = Should be anytime) \\ 
 +[2] Bytes - Unknown \\ 
 +[4] Bytes - Number of Loops (Usually either 1 or 9999) \\ 
 +[4] Bytes - Unknown (relative to number of loops, should be memory allocation) \\ 
 +[4] Bytes - Unknown (usually nothing) \\ 
 +[2] Bytes - Unknown (relative to sound volume. Should be either initial gain or user gain.) \\ 
 +[2] Bytes - Unknown (relative to sound volume. Should be either initial gain or user gain.) \\ 
 +[2] Bytes - Unknown (3D volume or Head Relative) \\ 
 +[2] Bytes - Unknown (2D volume?) \\ 
 +[4] Bytes - Location to Play sound (X) {Float} \\ 
 +[4] Bytes - Location to Play sound (Y) {Float} \\ 
 +[4] Bytes - Priority \\ 
 + ​\\ ​
 +*Upon Last Entry after this loop. If the 4 bytes has value, push to next section.
 +==== Event Listings ====
 +//Only Exists in Ingame.Met//​ \\ 
 + ​\\ ​
 +[4] Bytes Number of Entries \\ 
 +
 +=== Event Loop ===
 +[4] Bytes - String Length \\ 
 +~ String (Event Name) \\ 
 +[4] Bytes - Number of Sounds to Associate with Event Name \\ 
 +~Then Based on number of sounds to associate are 4 byte ID listings \\
