UniMic

UniMic turns your iPhone into a wireless microphone for your computer, letting you capture audio from your phone and stream it directly to a receiver on your desktop or laptop over your local network. You can enter your computer’s IP address and port, choose your preferred input source, and start sending live microphone audio from your phone, making UniMic useful for recording, voice chat, streaming, presentations, and other situations where you want to use your phone as a microphone for your computer.
