Sound data - voice navigation pack

Each voice navigation voice pack is defined in a separate configuration file. Configuration file is located in this game data folder:

    /base/sound/navigation

The file can be named arbitrarily but good convention is "language_actor".sii

File is very simple unit with these attributes:

Attributes

Name	Type	Default Value	Description
pack_name	string		Name of the pack (shown in the game). Format "Language - Actor name (Optional Variant)" (e.g. "English - Skye (UK)")
pack_dir	string		Name of the folder with sound files. (e.g. pack_dir: "/sound/navigation/english_skye_uk")

Good practice is to use the same name for the configuration unit file and for the folder with sound data.

Sound data folder

Files in the folder are in the ogg format (with .ogg extension). Content of the file is determined by file name prefix (see next table).

Files with the same prefix are used for the same command and their usage is randomized.

(We strongly recommend using only one file for each traffic command. Randomization of this is very unintuitive.)
