Open Soundboard plays .mp3 files from a folder inside your Minecraft directory. You can sort them into nested folders and mark the ones you use most as favorites.
Adding your sound files
1. Close the soundboard screen if it is open.
2. Open your .minecraft folder. This is the same folder that holds resourcepacks and saves.
3. Find the opensoundboard folder and open it.
4. Copy your .mp3 files into it. The FACTS only mention MP3, so convert other formats such as WAV or OGG to MP3 first.
5. Back in game, press U to open the soundboard. Your tracks appear in the list.
Building a folder structure
The soundboard supports nested folders. Use them to keep a big collection manageable:
1. Inside opensoundboard, create subfolders such as memes, music or effects.
2. You can put folders inside folders, for example music/intros.
3. Move your MP3s into the matching folders.
4. In the soundboard screen, open a folder to see its contents.
5. The current location is shown as a clickable path. Click any part of the path to jump straight back up to that folder.
Using favorites
If you replay the same clips often, mark them as favorites from the soundboard screen. That way you don't have to dig through folders every time.
Tip: Give files short, clear names. The filename is what you'll be scanning for in the list, so airhorn.mp3 beats track_0042_final.mp3.
