Transcribe 'UnmixedMeetingAudio' buffer as soon as those are received.

This is a question to the community but not an issue. I am able to receive unmixed audio in AudioMediaReceived event handler inside CallHandler.cs class, during P2P or group call/online meeting. Now I want to generate transcript out of it. I want some guidance about:

1. Can this be done at the end of the meeting, I am confused as it's stated on a number of places that

"You may not use this SDK to record or otherwise persist media content from calls or meetings that your bot accesses" .

In which scenario this fits? Is to possible to generate wave file out of the byte array (UnmixedAudioBuffer data) received and use that for transcription at the end of the meeting?

2. Since we receive audio frames at a very quick pace (50 frames per second), If I am to generate the transcript asynchronously and real time, how should I do it. Is it about converting buffer data to .wav or in memory stream and using some cloud speech service/API?
   There's a speech service provided by Microsoft as well as speech to text resource provided by Google cloud.
   your guidance is highly appreciated.

Start with the AudioMediaReceived event handler in CallHandler.cs and the UnmixedAudioBuffer data described in the issue. Review the SDK restriction on recording or persisting call media before assessing the proposed end-of-meeting and real-time transcription approaches. Done would be clear guidance on whether either workflow is permitted and how it should handle the received audio frames.
