As an Interleaf file, JUKEBOX.SI is a container for a large number of asset files. Most of these files are background and radio music (including the radio voices) in Microsoft {{Wikipedia|WAV}} audio, however there are also 4 [[FLIC]] video files for each of the building rooms (dune buggy, jetski, helicopter, and race car). These FLC files are the small instructional videos played in the screen and are interleaved together as "movies" that are equal length (thus looping together). | As an Interleaf file, JUKEBOX.SI is a container for a large number of asset files.

All audio in JUKEBOX.SI (like most of LEGO Island's audio assets) is mono uncompressed PCM. While the majority of tracks are sampled at 11025 Hz/16-bit, a handful are sampled at 22050 Hz/8-bit. These can be distinguished by each track's WAV header (the "fmt " section if you're familiar with WAV headers) left intact in the first [[MxCh|chunk] of their respective streams. | All audio in JUKEBOX.SI (like most of LEGO Island's audio assets) is mono uncompressed PCM.

When replacing, the WAV "fmt " header can be directly transplanted over the existing data in said first chunk. All WAV formats are compatible. The PCM data can be transplanted too, but it must be interleaved into chunks. | When replacing, the WAV "fmt " header can be directly transplanted over the existing data in said first chunk.
