# Audio masters

The source files the shipped audio is made from. Versioned, but **not part of
the game**: the empty `.gdignore` beside this file tells Godot to skip this
folder entirely, so nothing here is imported into `res://` and nothing here
is carried into an export.

That split is the point. `SPACE_4.wav` is 59MB of 16-bit stereo; the theme
the game actually loads is `../space_4.mp3`, the same 5m36s at LAME 160k in
6.7MB. Shipping the WAV as well would put 59MB into every Android and web
build for a file nothing opens.

| master | shipped as | made with |
| --- | --- | --- |
| `SPACE_4.wav` | `../space_4.mp3` | `ffmpeg -i SPACE_4.wav -c:a libmp3lame -b:a 160k ../space_4.mp3` |

The sound effects have no master here - they are generated outright by
`../make_sfx.py`, which is their source.
