Description: 

GameRip Global (Steam Version, late July – early August 2025)

The game’s music assets are stored in CRI AWB files — a proprietary container format developed by CRI Middleware, commonly used in Japanese video games for audio streaming. CRI AWB files typically store ADX-encoded streams, offering variable quality; in this particular case, most tracks had an original bitrate of approximately 192 kbps, with some select tracks encoded at 384 kbps. The sample rate for all files was 48 kHz.

Within the game archives, these AWB files are encrypted. To access them, the Umamusume Asset Extractor tool was employed, allowing the extraction of the original encrypted AWB containers.

For initial project planning and asset verification, the UmaViewer utility proved useful in the early stages, helping to map out the workflow and confirm the presence of desired audio files.

Once the AWB files were obtained, they were converted to WAV format using VGMStream — a tool specialized in decoding various video game audio formats, including CRI-based containers. These intermediate WAV files were then transcoded to FLAC for archival purposes, preserving the extracted audio in a lossless format. For distribution and playback convenience, MP3 versions were also generated from the FLAC masters.
