This is a very important feature:

I need to record audio on client A and send it in realtime using a server to client B to then play the audio.
-I need it to make a voice call with others.

What I have so far:

1. https://pub.dev/packages/audio_streams#-readme-tab- - Gives a byte-stream of the microphone for iOS only
2. https://pub.dev/packages/mic_stream - Gives a byte-stream of the microphone for Android only

--

1. It is not convenient for such a simple feature to be handled platform specific (or without an abstraction)
2. There is no way (I have not found one) to use a byte-stream to then play it directly as a sound!
   -That is the important part!
