A Godot plugin that ports sfxr, the popular program of choice to make retro sound effects for games.
You can use sfxr sound files like regular audio files in Godot and edit sound files like in the original sfxr.
🚧 Checkout the godot-4 branch if you want to use this plugin in Godot 4.
This is a regular plugin for Godot. To install, download the ZIP archive, extract it, and move the
addons/ folder it contains into your project folder. Then, enable the plugin in project settings.
After enabling the plugin, you'll see a bottom panel named "gdfxr" appear. This is the sound editor.
Buttons on the left are sound generators of 7 different categories. There are also an option to mutate the current sound slightly, and an option to generate a completely random sound. These are the buttons you'll be working with most of the time.
After a random sound is generated with the generator buttons, you can fine-tune the sound with the controls on the right.
The generated sound can be saved and edited later as an .sfxr file.
These files only contain the generator parameters, so they are only about 100 bytes.
But they can be used directly as regular AudioStreams.
If you want to reuse an existing sound from the original sfxr, make sure to save it with an
.sfxr extension. You can also load & edit the .sfxr file with the original sfxr.
Options for changing Looping, Bit Depth, and Sample Rate are available as import options
of the .sfxr file. You can find these options in Godot editor's Import dock.
Note: Due to performance constraints with GDScript, the editor may freeze a bit when generating
long sounds. This only happens in-editor.
Using .sfxr files in-game won't generate anything at runtime.
