gDAW

A Godot Plugin for generating sound in real-time

Description

gDAW is a tidy little plugin that adds its own custom nodes that allow users to generate audio in real-time using Waveforms and ADSR Envelopes. These custom nodes have many settings that can be used to adjust the sound created.

Installation

Follow the standard Godot instructions for downloading and enabling a plugin. gDAW can be found on the Godot Asset Library here.

Configuration

gDAW's custom nodes depend on a couple of global variables that must be autoloaded. These values can be tailored specific to your project, but the defaults should fit just fine for most use cases.

1. Create a new AutoLoad in the Project Settings for your project. Give it the name "GDawConfig" (this must match exactly) and set the path to res://addons/gdaw/gdaw_config.gd. You can also copy this script and put it wherever you'd like, just be sure that the Autoload's path is pointing at that script.

2. That's it! You're ready to start making some noise!

Global Vars

The following global variables can be modified as needed by editing the script of the Autoload that was created during the Configuration steps:

• max_db: The maximum volume (in decibels) any custom nodes provided by gDAW can reach
• min_db: The minimum volume (in decibels) any custom nodes provided by gDAW can reach
• sample_rate: This is the waveform sample rate that gDAW uses to create sound. Values between 22050 and 32000 are recommended. A higher value will result in a cleaner, smoother sound, while introducing an increasing amount of audio lag, as it requires more CPU to create the audio. The lower the value goes, the more scratchy and static-y the sound will get, due to the "resolution" of the sound being lower.

Roadmap

Here is a short list of things I'd like to add to the plugin when I've got some time:

1. An in-editor gui for manipulating the ADSR envelope, like most modern DAW software has
2. A custom Envelope node that would allow users to apply ADSR envelopes to ANY value on ANY node (this may actually be better as its own independent plugin, since it wouldn't necessarily be related to generating real-time sounds).
3. A custom LFO node
4. A Chord node for easily playing multiple waveforms at the same time (experimental)
