+## Emberwild's own (CC0)
+`music/`, `ambience/` and `sfx/synth/` are synthesised from scratch by
+`tools/audio/make_audio.py` (no samples): the five music tracks (calm,
+night, storm, danger, boss), the birds, crickets and fire crackle, and the
+swings, eating, splashes, the fishing reel and bite, the bow, the hurt thump
+and death. Released under CC0 like the rest of this folder.
