And eventually:

"The incoming pcm16Buffer has 4800 samples"
"Received ws disconnect. The operation couldn’t be completed. Socket is not connected"
"The incoming pcm16Buffer has 4800 samples"
Done listening for messages from OpenAI
"The incoming pcm16Buffer has 4800 samples"
"Interrupting playback"
"The incoming pcm16Buffer has 4800 samples"

Not able to speak or listen any input or output, wondering what I may be doing wrong 😑

Tested on device iPhone 16 pro

Permissions for microphone and audio has been granted for this demo

RealTimeAPIViewModel and RealTimeAPIDemoView is how i try to test this. All the code has been copied from demo branch

@lzell do you mind taking a look in case on top of your head you think my web socket gets disconnected? I am a bit lost on this one :/

[lzell]

Isn't that fix amazing :)

Just dropped some audio notes here: https://community.openai.com/t/audio-notes-for-openai-realtime-on-apple-platforms/1108404

I'm really hoping to release the shared core soon. Hoping next week
