About AudioRelay

AudioRelay is an application for streaming audio between a computer and a phone. It can send a PC or laptop's audio to a phone in real time, letting the phone act as a wireless speaker or headset, and it can send a phone's microphone audio to a PC over Wi-Fi so the phone works as a microphone.

Connections can be made wirelessly or over USB, and audio can be sent to multiple devices so several people or rooms can listen at once. The site states that PC audio is sent in real time with lower latency than Bluetooth, though results will depend on the setup used. Pricing is not stated on the homepage.
