Would you help me out by describing what types of properties would need recompilation? I've attempted to avoid this particular issue by limiting the data types and not allowing index...

Yes I think the language of the extension allows that. Though supplying a requires or uses extension should be necessary as those properties are undefined without the target extension.

This extension was a proposal for something we were thinking about internally, unfortunately we are no longer perusing those plans. I started with EXT because I was able to prototype...

No engines or tools that I'm aware of. The PR includes pointers to sample implementations in ThreeJS, Babylon, and Blender but all of those are out of date with their...

We at Microsoft developed an extension [MSFT_audio_emitter](https://github.com/KhronosGroup/glTF/pull/1400) that we implemented for Windows Mixed Reality environment. As specified it doesn't allow MP3 but I believe we can change that at this...

Oh and Babylon.js also supports MSFT_audio_emitter.

We built a custom tool that would add audio to a GLB. It was based on [3D Viewer](https://www.microsoft.com/en-us/p/3d-viewer/9nblggh42ths?activetab=pivot:overviewtab) but we haven't gotten it to a place where we would like...

Love that this space is getting more attention. I am a little concerned about the elimination of a number of features that MSFT_audio_emitter has. Some limitations are understandable such as...

We picked wav because its commonly available and trivial to decode almost anywhere. Continuing with the runtime friendliness of glTF and the desire to use linear PCM decoded audio data...
