AirheadWaves

AirheadWaves sends audio playing on an Android phone or tablet across a WiFi network to a Linux machine, which handles the playback. The arrangement suits situations where the sound is on the handset but the speakers worth listening to are attached to a desktop, a laptop, or a small board computer on the same network.

Because the transport is the local network rather than Bluetooth, the pairing step and the range limits of a radio link are replaced by whatever the WiFi coverage allows. The receiving side is a Linux system; Windows and macOS targets are not part of what is described here, and the sending side is Android only, so both halves of the setup are fixed.

Stephen Brady publishes the project under the MIT licence. As with any networked audio path, the practical result depends on the quality of the connection between the two machines, since latency and dropouts follow the network rather than the app.
