Stream audio from iOS

Question

How would I go about streaming audio FROM an iOS device to another device like a Mac or another iOS device? I can only find solutions like AirPlay on Google and nothing abou

Answer 1

crude VOIP use case:

Step 1. record audio with AV Foundation using a compressive encoder
Step 2. Stream packets to another device (ie RTP)
Step 3. Decode & play the audio packets on the remote device

More complex VOIP uses case include discovering users, establishing connections.
