I found an old 2012 unity feature request: Unity Feedback - Web player support for Wwise
This was declined with “We do not plan to integrate WWise into the engine”.
Probably a lot has changed since the unity web player era, are there any plans on bringing Wwise to the WebGL platform as it is one of the biggest audio middleware in the market.
There is a converter that small projects can maybe use to produce WebGL builds, but as the author puts it: “The objective of this tool isn’t to reproduce Wwise”: https://github.com/Aredhele/WwiseUnityAudio
It would be a game-changer for game-jam projects as FMOD’s free license doesn’t allow more than one game a year.
