The Xbox allows for soundstracks to be stored on the harddrive and played in-game. Music is copied from audio CDs using the dashboard and converted to WMA audio files. The notes gathered here are from decompiling StDB.dll from Xbox Soundtrack Manager.
Contents
Folder Structure
All soundtrack related data is stored in E:\TDATA\fffe0000. Songs are organized into groups of folders containing up to 6 WMA files. Zero-padded 4 decimal integers are used for the folder names, and zero-padded 8 decimal integers are used for the WMA file names. Metadata such as song title and which soundtrack a song belongs to is stored in the ST.DB file
ST.DB
The ST.DB file contains information about soundtracks loaded on the Xbox. Up to 100 soundtracks with 500 songs each can be used. Each header and struct described below is padded to 512 bytes.
File Layout:

0000 Main Header
0200 Soundtrack Struct 1
0400 [Soundtrack Struct 2]
...
CA00 Song Group 1
CC00 [Song Group 2]

Default Encoding Settings
These are the encoding settings used by the dashboard when encoding WMA files:
| Key | Value |
|---|---|
| Format | WMA Version 2 |
| Codec Description | Windows Media Audio V8 |
| Encoding Tool | Windows Media Encoding Utility 8.0.0.403 |
| Bit Rate | 128 kbps |
| Channels | 2 |
| Sampling Rate | 44.1 kHz |
| Bit Depth | 16 bit |
The track number is added to the metadata.
