Soundbanks

A soundbank is a binary file in Audiokinetik's prorprietary format that organizes information in various sections. The most important sections are the HIRC (Hierarchy), where playback graphs are stored, and DATA, which contains (most of) the audio data.

Info

For now, Yonder does not parse the raw soundbanks and instead relies on rewwise, which extracts the audio data as .wem files and the other sections into a large .json.

Important Soundbanks

In recent Fromsoft games, soundbanks were organized as follows:

Bank	Description
init	Busses and most project-wide sections.
cs_main	Character sounds that should always be loaded as well as ambience soundscapes.
cs_smain	All music tracks, including boss themes.
cs_cXXXX	Character-specific sounds.
vcXXX	Character-specific (localized) voice lines.
cs_mXX	Map-specific sounds.
cs_smXX	Sounds for cutscenes (by map ID).
*	Others will usually be game-object specific, e.g. aeg for game assets.

To make your own soundbank, follow this guide!

Sections

Section	Description
BKHD (Bank Header)	Soundbank metadata, e.g. name, version, project, etc.
DATA (Audio Data)	Stripped audio data, typically in Ogg Vorbis format.
DIDX (Data Index)	Index and metadata for the DATA section.
ENVS (Sound Environment)	Curves for altering sounds based on obstruction and occlusion.
FXPR (Effects Properties)	Unknown for now beyond what can be guessed from the name.
HIRC (Hierarchy)	Graphs of playback nodes like containers, events, audio sources, states, etc. This is the main section you will interact with in Yonder. See node types for more details.
INIT (Init)	Lists (effect) plugins used by this soundbank.
PLAT (Platform)	Platform specific metadata.
STID (Short ID (?))	Contains references to other soundbanks that may be referenced by nodes in this soundbank.
STMG (State Management)	Defines transition times for states and switches. Also includes acoustic texture presets, which define diffraction and transmission parameters.
