Wonderland Engine 1.5.2 - Audio Encoding and Bugfixes

Audio encoding, quality-of-life changes, and stability improvements.

Audio Encoding

Audio clip resources were added in 1.5.0. They significantly improved the deployment workflow, but were still missing an important feature: Audio encoding!

A frequent download-size culprit in 3D, WebAR, and WebXR projects is the size of the audio files: often WAV, or FLAC files slip into deployments and make up a surprising portion of the package size.

Wonderland now compresses any raw audio resources (.wav and .flac) to OPUS – a modern royalty-free audio standard supported by all major browsers. The resulting stream is serialized into a WEBM container.

Files are compressed to 96kbit/s VBR, roughly comparable in quality to MP3 at 192kbit/s. This means OPUS is higher quality at smaller sizes.

We may expose compression settings in a future version. If you supply pre-compressed audio files, Wonderland Editor will not transcode them. You are free to use audio with a different quality or codec altogether.

Editor Plugins

For plugin packages, we are moving package.json metadata to help Wonderland Editor find plugins:

 1{
 2    // ...
 3    "wonderlandengine": {
 4        "plugins": [
 5            {
 6                "name": "My Plugin A",
 7                "main": "src/plugin-a.mjs"
 8            },
 9            {
10                "name": "My Plugin B",
11                "main": "src/plugin-b.mjs"
12            }
13        ]
14    },
15    // ...
16}
