Audio needed its own workbench. The music collection includes all 82 extracted BRSTM streams, including shorter cues and ambience as well as looping tracks. Together they run for roughly one hour and 48 minutes. The player uses readable source filenames; it does not invent official soundtrack titles.
Fifty-nine streams carry native loop-point metadata. The standalone player provides search, track selection, seeking, volume, shuffle and repeat. The stage also lets players choose music without leaving the game. Pause and global mute follow the game, while restarting a run keeps the selected song.
Samples and cues are different views
The sound tester separates 297 exact decoded source waves from 441 registered cues. Source samples play as WAV audio. Cue previews reconstruct sequences from the original samples; 434 are playable, while seven cues that reference empty instrument slots remain visible and disabled. Empty native slots are preserved instead of being filled with invented sound.
Some sequence-envelope and modulation details are approximate, and browser MP3 seeking cannot promise sample-exact native loops. Those limits matter when comparing a preview with the source. The library keeps the exact decoded samples available, and game actions use the existing native-sample renders with a fallback when a browser cannot play them.
