 +====== Sound (DED) ======
 +
 +A **Sound** definition is used to define the presence and in-game playback characteristics of a sound effect sample.
 +
 +
 +===== Core Concepts =====
 +
 +
 +==== Sample References ====
 +
 +A reference is used to link actual sound data samples to a //Sound// definition. Only one sample reference is actually required and in general, only one is specified in each definition. If multiple references are specified they will be tried sequentially until one succeeds, in the following order (top to bottom):
 +
 +  *  [[#Ext]]
 +  *  [[#Lump]]
 +
 +
 +==== Linked Sounds ====
 +
 +The [[#Link]], [[#Link Pitch]] and [[#Link Volume]] parameters should never need to be used under normal circumstances. It could also be largely considered a legacy feature as one can write their own sound definitions for almost everything these days.
 +
 +Several actors in the original Heretic (and also the Chaingun in Doom, though this particular case is broken) used the same sound for multiple things. In the early days, to give modders more flexibility,​ these uses were given separate sound definitions.
 +
 +Linking //Sound// properties make this possible without breaking [[dehacked]] support. Essentially,​ if Dday calls a sound def with a link field, it will use the linked to sound def instead.
 +
 +
 +===== Syntax =====
 +
 +  ​
 +  Sound {
 +    Id = "";​
 +    Name = "";​
 +    Ext = "";​
 +    Lump = "";​
 +    File = "";  ​
 +    File Name = "";  ​
 +    Flags = "";​
 +    Group = 0;
 +    Max Channels = 0;
 +    Priority = 0;
 +    Link = "";​
 +    Link Pitch = 0;
 +    Link Volume = 0;
 +  }
 +
 +
 +
 +==== Id ====
 +
 +Unique identifier of the sound. Used as a reference to this sound in other definitions. Note there is no limit on length, spaces etc.
 +
 +
 +==== Name ====
 +
 +Unique symbolic name of the sound. Used as a reference to this sound only in [[sndinfo]] and [[sndseq]] definitions.
 +
 +
 +==== Ext ====
 +
 +Name of a sound [[external_resource_file|file]]. Used to locate the sample from a native or virtual file (e.g., in a [[zip]]). See [[#​Sample_References]]
 +
 +
 +==== Lump ====
 +
 +Name of a sound [[lump]]. Used to locate the sample from a [[wad]] archive. See [[#​Sample_References]]
 +
 +
 +==== File ====
 +
 +Alias of [[#Ext]]
 +
 +
 +==== File Name ====
 +
 +Alias of [[#Ext]]
 +
 +
 +==== Flags ====
 +
 +
 +^ Flag ^ Description |
 +| shift | Use type 1 periodic random frequency shifting on the sample. |
 +| shift2 | Use type 2 periodic random frequency shifting on the sample (x2 magnitude). |
 +| exclude | When sample playback begins all other playing samples in the same group will be stopped (otherwise just those of the same emitter will stop). Used in conjunction with the [[#​Group|exclusion group]] feature. |
 +| nodist | Sample will always be heard at full volume. |
 +| repeat | Sample playback will repeat continuously until stopped (either by another sound or an in-game action). Used in conjunction with the [[#​Group|exclusion group]] feature. |
 +| dontstop | Sample playback will never be stopped by another sound. |
 +
 +
 +
 +==== Group ====
 +
 +Sound exclusion group. If non-zero all other sounds in the same group will be stopped when this one sound is started. For example, in [[j_doom]] a group is used to ensure that both the chainsaw rev up and idle sounds cannot be heard playing simultaneously.
 +
 +
 +==== Max Channels ====
 +
 +Maximum number of sound channels this sound is allowed to populate simultaneously.
 +
 +
 +==== Priority ====
 +
 +
 +
 +==== Link ====
 +
 +See [[#​Linked_Sounds]]
 +
 +
 +==== Link Pitch ====
 +
 +See [[#​Linked_Sounds]]
 +
 +
 +==== Link Volume ====
 +
 +See [[#​Linked_Sounds]]
 +
 +
 +===== Examples =====
 +
 +  ​
 +  # (Basic) Using a lump sample.
 +  Sound {
 +    Id = "​pistol";​
 +    Lump = "​DSPISTOL";​
 +  }
 +  ​
 +  # (Intermediate) Using a native file sample with greater priority and shift.
 +  Sound {
 +    Id = "​pistol";​
 +    Ext = "​sound/​kaboom.wav";​
 +    Flags = shift2;
 +    Priority = 64;
 +  }
