AudioRelay0.27.5

Send the sound from a PC or laptop to a phone with AudioRelay, letting the mobile device act as a remote audio endpoint. The same connection can carry microphone input in the opposite direction, so the phone’s microphone becomes available to the computer. This solves the practical problem of accessing computer audio or adding a convenient voice-input source without relying on the computer’s built-in microphone.

AudioRelay streams audio between devices, supporting a two-way arrangement rather than limiting the phone to playback alone. Someone working at a computer can listen to its audio through a phone, while a user who wants to speak to the computer can use the phone as the microphone. It is suited to people who switch between a computer and phone during work, communication, or other audio-focused tasks.

The MacOS edition is categorized as Music & Audio and runs on Apple Silicon (arm64). The current version is 0.27.5. AudioRelay is freeware, making its cross-device audio functions available without a paid license tier.
