Dear members,

I'm facing a pretty interesting challenge, which is: "How to connect multiple smartphones in the quickest and simplest way and leverage their microphones for a shared recording?"

Here is a use case. I go into a meeting with a group of random (strangers) that all have smartphones, Android, iOS, Windows. Now I want to record this meeting and in doing so I would like to leverage the mic's of all the phones in the room. How can I get the phones to connect with my system, or maybe using the cloud, to capture all the recordings in one platform. The main difficulty being that the other people in the meeting do not want to spend time installing an app of any kind. They should notice almost nothing, and do little to nothing.


My ideas:
- Using the android beam technology by holding phones against each other (only works on Nexus though)
- Using some sort of bluetooth system.
- Using NFC (near field communication)?
- Maybe I would have a unique URL that I can type into a webbrowser on each phone?


I'd love to have your thoughts, ideas, suggestions on this challenge, feel free to comment!


Best,
Peter
