AudioRelay: Stream Your PC Audio to Android Seamlessly

AudioRelay Setup Guide — From PC to Mobile in MinutesAudioRelay is a convenient tool that lets you stream audio from your PC to a mobile device (Android or iOS) over Wi‑Fi or USB. This guide walks through everything from prerequisites and installation to advanced settings and troubleshooting so you can get clear, low‑latency audio on your phone in minutes.

Go to the AudioRelay website or the project’s official download page.
Download the server for your OS (Windows/macOS/Linux).
Run the installer and follow on‑screen instructions. On Windows you may need to allow firewall access for the server.
Launch the AudioRelay server — it will display the PC’s IP address and listening port.

Android: open Google Play, search “AudioRelay”, and install the app.
iOS: if available, install from the App Store (feature set may differ from Android).
Open the app; it should automatically scan the local network for the PC server.

Ensure both PC and mobile are on the same Wi‑Fi network.
In the mobile app, select the PC’s entry (or enter the server IP and port manually).
Tap “Connect.” The app should start receiving audio within seconds.
Play audio on your PC (music player, browser, game). Sound should be routed to your phone.

Tips:

If you experience dropouts, try moving devices closer to the router or switch to a less congested Wi‑Fi band (5 GHz).
For best latency, use a 5 GHz network or wired Ethernet for the PC.

Enable Developer Options on Android: Settings → About phone → tap Build number 7 times.
In Developer Options enable “USB debugging” and, if needed, “USB tethering.”
Connect the phone to the PC with a USB cable.
In the AudioRelay PC server choose “USB” as a connection method (or the mobile app may detect the USB connection).
Connect from the app — USB typically gives lower latency and more stable throughput than Wi‑Fi.

On the PC server you can select which audio device to stream (default playback device, specific apps, or virtual audio cables).
Use virtual audio cable tools (e.g., VB‑Cable on Windows) if you need to stream a specific app only. Route system audio to that virtual device and select it in AudioRelay.
Volume controls exist both on PC and mobile — adjust whichever is most convenient.

Sample rate and bit depth: increase for higher fidelity, decrease for lower latency and less CPU usage.
Buffer size: smaller buffers lower latency but may increase dropouts; find a balance for your network.
Bitrate: higher bitrates yield better sound but consume more bandwidth.
Use UDP mode (if available) for lower latency; TCP is more stable but slightly slower.

For gaming, prioritize low latency: use USB or 5 GHz Wi‑Fi, reduce buffer size, and disable unnecessary network traffic.
For voice chat apps, consider routing only the game audio through AudioRelay while keeping microphone and chat app on the phone or PC to avoid echo and double audio paths.

No connection detected: verify both devices are on the same network and firewall allows the server.
App can’t find server by name: use the server’s IP address and port manually.
High latency or stuttering: switch to USB, use 5 GHz Wi‑Fi, reduce buffer size, or close bandwidth‑heavy apps.
No sound from certain apps: use a virtual audio cable to capture that app’s output specifically.
Permission prompts on Android: allow microphone or USB debugging prompts when requested.

Virtual audio cables (VB‑Cable, Jack Audio, PulseAudio) — for fine‑grained routing on PC.
Bluetooth speakers/headphones — simpler but often higher latency than AudioRelay.
Other streaming apps — compare latency, features, and platform support.

If you want, I can:

provide step‑by‑step commands for installing the server on a specific OS (Windows/macOS/Linux), or
write instructions for setting up a virtual audio cable for streaming only one app.
