Does anyone know how I could have spatial audio in WebGL ?
Both the Oculus spatialiser and Resonance don’t work since they use DLLs 
Quite hard to make an actual good WebXR app without any spatial audio
Hello,
please go through the below-mentioned doc. I hope it will help you out:
This does not help answering the question of a spatialized audio implementation for WebGL.
I am a beginner with Unity, but I came across Google Resonance as a solution for implementing spatialized web-compatible audio. However, it’s been deprecated since the 2020 version.
I haven’t been able to find a good solution to this, and I don’t like my immersive 3D WebGL project playing audio sources in mono. It’s incredibly frustrating that there is no clear solution to this.
Check this post , a bug was present since a long time and it has been finally fixed recently.

6 months to get this fixed… but still fixed …
