Wwise by AudioKinetic is a feature rich audio solution for games. Wwise is in many ways similar to FMOD (for which we have a Defold extension), but also does things a bit differently compared to FMOD.
The Defold Foundation is currently in talks with AudioKinetic about the creation of a Wwise extension, and we are now looking for developers that have games in development where the built-in sound system of Defold is not good enough. Developing an extension such as Wwise is best done in collaboration with one ore more developers so that the extension can be tested in a real game to make sure that the API and initial set of supported features makes sense to Defold game developers. Please reach out in a PM if this sounds (pun intended) interesting to you!
