SMR.szs
| This page is in progress and may contain incomplete information or editor's notes. |
|---|
SMR.szs is a compressed BAA file (Binary Audio Archive) which defines the game's sound system. It contains references to streamed and sequenced music files as well as data for sound effects and instruments. It can be found in various JAudio games, however the specifications below mainly apply to Super Mario Galaxy and Super Mario Galaxy 2.
The following files are directly linked to SMR.szs:
- AudioRes/Info/BgmParam.arc (SMG2 only, overrides the BGM and STM volume parameter)
- AudioRes/Info/JaiChord.arc (SMR.szs links BGM labels to CIT file IDs within this archive)
- AudioRes/Seqs/JaiSeq.arc (SMR.szs links BGM labels to BMS file IDs within this archive)
- AudioRes/Stream/*.ast (SMR.szs links STM labels to AST files)
- AudioRes/Waves/*.aw (SMR.szs defines the contents of AW files)
The following files are indirectly linked to SMR.szs:
- AudioRes/Info/ActionSound.arc (SMG2 only, links hardcoded triggers for all objects to sound effects in SMR.szs)
- AudioRes/Info/JaiMe.arc (References instruments from SMR.szs)
- AudioRes/Info/JaiRemixSeq.arc (References instruments from SMR.szs)
- AudioRes/Info/MultiBgmInfo.arc (SMG2 only, connects MBGM labels to STM and BGM labels, allowing streamed and sequenced audio to play simultaneously)
- AudioRes/Info/SoundIdToInstList (SMG2 only, references Sound IDs and instruments from SMR.szs and allows loading AW files)
- AudioRes/Info/StageBgmInfo.arc (SMG2 only, controls the main music and music changes for all stages)

Editing SMR.szs
The following section contains instructions for editing SMR.szs with the SoundModdingToolkit. They do not contain specifications for the file itself.
The tool SoundModdingToolkit can convert this file into a clear and readable file structure, so the structure of the file is shown on this page using the tool's converted structure.
Please note that only version 4.1.0 can edit the lists without any problems. Later versions can lead to problems such as muted songs.

SE
AW
Each aw. file is converted by the tool into a folder that has the ID of the aw file in its name, and besides the sound files converted in wav format, contains the following settings for each sound:
- manifest.json Contains the ID and name of the aw file
- wavetable.json Contains settings for each sound of the aw. file
wavetable
Each entry starts with the name of the Wav file (e.g. "31") followed by its settings:
| Name | Description |
|---|---|
| format | ? always 0 |
| key | |
| sampleRate | The sample rate at which the sound should be played. (e.g. "22050.0") |
| sampleCount | Length of the sound in samples |
| loop | Whether it should be looped or not true: loop false: do not loop |
