Spatial audio doesn't work in iOS12.01 safari #22

Hi. I tried resonance Audio SDK for web in (iOS12.0.1/safari & OSX10.13.6/safari) . But it did't work at all. Official Web sample didn't play any sound in this environments.

In iOS11.2.5, it seems to work well. Would anyone tell me this reason?

Just to clarify: Safari on iOS 11.2.5 = Working Safari on iOS 12.0.1 = Not working Safari on OSX 10.13.6 = Not working

Do you see any error messages in the developer console?

@hoch Thank you for reply. In iOS 12.0.1 and OSX10.13.6, Hello world Demo show these message when push play button. There was nothing error message.

I think this is related to CORS issue. I am seeing the same problem when I run Omnitone example: https://rawgit.com/GoogleChrome/omnitone/master/examples/foa-renderer.html

MediaElementAudioSource outputs zeroes due to CORS access restrictions for https://rawgit.com/GoogleChrome/omnitone/master/examples/resources/4ch_B_FuMaNorm_FuMaOrd_speech.wav

At least Chrome Canary (72.0.3599.0) produces this error, so I can track it from there.

I can confirm:

https://cdn.rawgit.com/resonance-audio/resonance-audio-web-sdk/master/examples/room-models.html does not play any sound with Chrome 85.0.4183.109 on iOS 14.0.1.
When I download this repo, and host it all locally, the audio does play and the demo works. Though there is some audible noise. It seems somewhat rhythmic, so perhaps it's a buffer issue.

To summarize - this issue is definitely caused by CORS. But there might be more problems too.
