Working around the Cave Story+ “Soundtrack”

TL;DR: Here’s a bash script to build soundtrack files from the resources for the “remastered” music option is.

So I’m feeling like listening to the Cave Story+ remastered version of the title page tune that better fits the SNES-era ambiance of the game’s original visuals. No problem. The Humble Bundle gave me the soundtrack… but it doesn’t contain that version.

…it contains the version from the much maligned DS soundtrack (plantation.ogg) and some weird remix of the original NES-like version (intro menu.ogg) which uses the same instruments but with a different beat. I’m no expert but, judging by the way I hate it, I think it’s jazz.

Ugh. If I wanted to listen to a cover, I’d listen to Brentalfloss’s version with lyrics. Time to use what came in the game… OK, each track is two Ogg Vorbis files (a lead-in clip and a loop clip). I can work with this.

I whip out a lossless Ogg Vorbis concatenation tool and it works… but the abrupt end isn’t nice. Long story short, here’s a little script which uses oggCat and sox to produce a soundtrack-like output file with everything except the ending fade-out being a lossless repackaging of existing compressed data.

It does give a couple of warnings on the console, but they seem to be harmless and I think that’s just because oggCat contains code that expects correct frame timestamps.

# Tool for generating acceptable soundtrack Oggs from Cave Story+ data files
# Usage:
# 1. Save this and chmod it executable
# 2. cd into CaveStory+/data/base/Ogg11
# 3. Run something like "~/ curly"
# 4. Enjoy your music
# Dependencies:
# - SoX
# - oggvideotools

if [ "$#" = 0 ]; then
    echo "Usage: $0 <track name> [...]"
    echo 'Note: The track name is the portion before the "_intro" or "_loop"'

for X in "$@"; do
    sox "${X}_loop.ogg" -C 5 "${X}_fade.ogg" fade h 0 6 6
    oggCat "${X}.ogg" "${X}_intro.ogg" "${X}_loop.ogg" "${X}_fade.ogg"
    rm "${X}_fade.ogg"
