Is it possible to get audiostream from RemoteVideoStream during video call in Azure Communication Service?

[h0las-dev]

I've started to investigate communication services for .Net recently and I've stucked with a problem: I want to get audio stream from my remote companion during video call and pass this stream to another service, make some analysis (convert audio to text and show like dynamic speech transcript for example. I want to use Azure Speech service for that). The problem is I don't know how to get audio stream from video stream or from call entity in this SDK.

Documentation is really poor and I don't know why because service looks very interesting.

I found only 1 example of usage Azure Communication Service in .Net here: https://docs.microsoft.com/en-us/azure/communication-services/quickstarts/voice-video-calling/get-started-with-video-calling?pivots=platform-windows

It works, however I didn't see anything connected with audio here. I even didn't see that in any entity from that example (LocalVideoStreeam, RemoteVideoStream, Call, some events and handlers, etc).

So, if anyone knows how to get audiostream using this SDK, it will really helpful for me. Also I will happy if someone can share any other usage examples video (or even audio calling) for .Net using this SDK because I found only 1 example and it's pretty poor.

Thank you!
