This is sPEAKer, my first ever mod!
Unlike the bugle, sPEAKer is an independent audio source. You can just press play and enjoy your music. Drop it, toss it around, audio will just not stop!

sPEAKer at the PEAK.
The main feature of this mod is that it works as a true portable speaker. Instead of playing 2D music for everyone, it leverages spatial audio to make it part of the immersive experience of PEAK.

It won't stop playing if you drop it.
Additionally, it supports MP3 and WAV out-of-the-box on top of your regular OGG files.
You can also download mixtapes from the Thunderstore or put together your own and share with friends, or even upload them too!
Playback control uses your regular interaction buttons, whatever they are.
Primary: Play/Pause toggle
Secondary: Next Song
Scroll: Volume Up/Down
Controller compatible.
After launching PEAK, your main music folder will be created:
.../plugins/onlystar-sPEAKer Music
You can place audio files directly in it, or you can use mixtapes.
A mixtape is simply a folder containing your collection of audio files.
Just create a new folder inside your main music folder (onlystar-sPEAKer Music) and drop your songs in it. The name of the folder will be used as the mixtape's name by default.
Optionally, you can also include a mixtape.json file inside your mixtape folder:
{
"name": "Undertale Bosses",
"author": "onlystar"
}
This takes priority over default naming, and will be shown in-game when a song from your mixtape starts playing.

Yes, it's "Mixtape Name - Song Name"
The idea behind mixtapes is that they are easy to share and organize.
Further updates will support extended metadata. Probably.
If you want to upload your own mixtape as a standalone mod, just put an empty sPEAKer.json file in the same folder as your mixtape folder.
You can follow the instructions in Manual Packaging as described here.
Your package should include manifest.json, README.md, /plugins folder and (hopefully) a 256x256 icon.png.
The plugins folder of your package should look something like this:
plugins/
├── sPEAKer.json
└── boss music/
├── a true hero.ogg
├── omega flowey.mp3
├── ...
└── mixtape.json
sPEAKer.json is the way of telling sPEAKer "this folder contains music".
Once your package is ready, ZIP it and upload it to Thunderstore.
💡 TIP: Keep your original package for updates!
If you wanna add songs to an already published mixtape, add your songs to the original (uncompressed) package and bump the version up in your manifest.json:
{
"name": "sPEAKer_Undertale_Boss_Music",
"author": "onlystar",
"description": "It fills you with determination.",
"version_number": "1.0.1", // <--- previously "1.0.0"!
"website_url": "",
"dependencies": []
}
ZIP it once again, and reupload it.
Disclaimer: Make sure you have permission to upload the audio files your mixtape contains to Thunderstore.
These are options you can change before starting your game.
You can find them in BepInEx/config/onlystar.sPEAKer.cfg
