I create content on a Windows computer and previously used WO Mic to turn my phone into a microphone. I'm now using Linux and tried AudioRelay, but I couldn't get it working and its one-hour limit is inconvenient. It also asks me to create and configure a virtual audio device, which I don't understand. I found an early-access app called MicStream that automatically creates the virtual device, but it includes ads and may remain limited to one hour. My phone is an Android Moto G52. What reliable, preferably free method can I use to connect it as a microphone on Linux, and how should the virtual input device be configured?

Since you’re using an Android Moto G52, check whether the app you choose provides a Linux client or a standard audio stream that Linux can expose as an input device. If it only sends audio over the network, you’ll still need to create a virtual source in PipeWire or PulseAudio and select that source in your recording software. Avoid relying on an early-access app with ads or time limits until you know it works reliably.
The exact Linux distribution, desktop audio system, connection method, and any error messages will matter here. Please include those details, since configuring a virtual microphone differs between PulseAudio and PipeWire. Also mention whether you’re connecting over USB, Wi-Fi, or Bluetooth.
