Tkinter desktop editor for YunYunLoader chart mods.

Run from this directory, or use ..\LaunchYunYunEditor.bat from the repo root:

python -m pip install -e .
python -m yunyun_editor

This is the main editor. It saves editable .denpa project files, keeps the project audio next to the .denpa, and exports YunYunLoader song.json, level JSON, .ogg, ZIP, or unpacked game folder structures.

Imported audio is normalized to OGG/Vorbis immediately. soundfile handles common PCM/FLAC/OGG paths; MP3/AAC/M4A and other compressed formats may require ffmpeg on PATH for the pydub fallback decoder.

Editor-owned audio assets live in assets/audio/.
