I already know how to stream video from my iphone to my cocoa server. it’s simple because videos come in different frames, and i can transfer them 1 by 1.
1- But how does the audio streaming works, how can i separate the data being read from microphone without interrupting the data?
2- How can i make sure that the audio matches the video, and keep the timing between them?
This is not a duplicate, there are questions with the same title, but the details are different.
The audio comes back from the OS in buffer data blocks of some length (duration of which is partially configurable) which you can transfer 1 by 1 just like the video. You can queue up and rechunk the blocks as necessary. If you attach a header to each audio transfer block, you can tag the audio data with a time stamp and/or the contemporaneous video frame capture ID.
