PSA: QOA has been added to Godot 4.3 as a compression mode for WAVs. This module now serves the purpose of providing it for previous versions.

Quite OK Audio for Godot

QOA is a lossy audio format with cheap decoding, designed to have dozens playing at the same time, with better quality and a similar decoding cost to IMA-ADPCM. This makes it an ideal format for sound effects.

Usage

This module enables you to use the QOA format in your project.

Importing follows two approaches:

QOA files

Drop a QOA file into your project's folder and it will be imported as is.

WAV files

• Click on a WAV file at the FileSystem dock, then go to the Import dock;
• On the Import As dropdown, where you see Microsoft WAV, choose Quite OK Audio.
• The import options are more or less the same as Microsoft WAV and will be carried over automatically if imported before;
• Reimport. The audio file will be encoded as QOA internally.

In both cases the audio will be imported as an AudioStreamQOA resource.

Building

Clone the repository into modules/. Make sure the folder is named qoa;

Before building, make sure to apply a patch to enable audio previews for QOA in the inspector. Run this command at the root of the engine's source:

git apply ./modules/qoa/inspector_audio_preview.patch

Finally, build the engine as usual.
