Sonic Adventure 2/Sound Effects

Sound effects are stored differently depending on the version of the game:
On Dreamcast and GameCube, the sound effects are inside MLT files in the root directory.
In the 2012 version, the sound effects are in folders found within the resource\gd_PC\MLT directory.
Event sound effects are in the event\MLT folder in the 2012 version, and as MLT files in the event folder for the Dreamcast/GameCube versions.

The 2012 version uses CSB sound banks to hold sound effects in ADX format. The following list denotes the contents of each CSB file as they're numbered. These numbers correlate to the soundbank IDs found within the MLT files and the names of the MPB files.

The internal order for the banks is different from what is displayed in the files, so extra care is needed when attempting to apply changes to sound effects using the logic found within the game's code.

General Sounds

The following sounds are found within the banks labeled as 0 within the MLT/CSB data. Almost every sound in this list is used universally, with a few samples being used and referenced in other sound lists.

Internal IDs that are italicized indicate that the ID is listed in a separate sound list, e.g. the sounds for the Lost Chao are used for Bank 1 instead of Bank 0.

Sound IDs that are italicized indicate that the sound may not exist within the MLT archive, but it does exist elsewhere within the game files.

By default, all of the sounds listed in the table are applied to the internal Bank 8 unless otherwise specified.

Character Sounds

The sounds in this section are labeled as 2 within the bank data stored in the CSB folder path/MLT data and occupy the internal Bank 2.

For single-player scenarios, the sound packs labeled as SE_CH_[character pair] are used. Multiplayer scenarios use the SE_CH_[character pair]_BATTLE files in SA2B, which does not exist in the Dreamcast version as the multiplayer characters don't utilize different sounds in that version.

The following lists are based on the sound data of the _BATTLE sound packs, which contains all of the data from the single-player variant alongside the added sounds for multiplayer characters.

Speed-type Action Sounds

All sounds in this list are found within the SE_CH_SS/SE_CH_SN_BATTLE sound data within the bank labeled as 2.

The sounds in this section can be found within the pack/bank labeled as 3 within either the MLT container or the folder paths containing CSB files. They can also be found as loose MPB files. All sounds in this category are loaded into internal Bank 3.

On Dreamcast and GameCube, the sound effects are inside MPB files in the root directory.
In the 2012 version, the sound effects are in folders within the resource\gd_PC\MPB directory.

The 2012 version uses CSB sound banks to hold voices in AAX format.

Event Sound Information

Events generally use the sound effects found in slot 4 within the MLT/CSB container. In the Dreamcast and GameCube versions, the sound data and sequence information is stored within the MLT file, with the sequence data sharing similarities with single-bank MIDI data. The 2012 version uses two files to replicate this effect: a CSB file containing all of the audio information, and a .mid file containing the sequence data. The 2012 version only has partial support for MIDI sequence data, so many of the audio manipulation settings will be ignored when set.

The sounds in this category are found within the banks labeled as 5 within the CSB folder path/MLT container. Each level/boss tends to use its own sounds with occasional overlap depending on the situation. Most of the sounds present in this pack are usually tied to stage-specific objects. All sounds attributed here are loaded into internal Bank 0 unless otherwise specified.
