After pairing, you can send your PC’s sound to your PC-connected Android device—without being restricted by cable length—so you can enjoy your audio from anywhere. The app is built for broad compatibility and works with most Android phones and PCs. With the included tutorials, setup is straightforward, and you can fine-tune both sound quality and connection stability to suit your needs.

AudioRelay also lets you sign in across multiple devices, so you can keep your connection to your PC and switch smoothly when you need to.

Key Features of AudioRelay

• Wireless speaker mode: Turn your Android device into a Wi‑Fi or USB wireless speaker for your PC.
• Low-delay playback: Receive PC audio over your network with minimal latency—ideal for gaming and movie watching.
• USB tether support: Using USB tethering can reduce lag risks and provide a more stable connection than Wi‑Fi in some setups.
• Opus audio compression: Compresses audio to lower network usage, which helps when bandwidth is limited or when several devices share the same network.



• Custom buffer settings: Adjust buffer sizes to balance smooth playback, stability, and audio quality based on your environment.
• Microphone mode: Use your Android phone as a microphone for your computer (useful for voice chat, online games, or recording). You can switch between listening and using the phone mic without extra hardware.
• Audio sharing: Route your phone’s audio to your PC or share audio with another Android device. This requires Android 10 or later.
• Remote volume control: Change your device volume directly from your PC, so you don’t need to jump between screens just to adjust levels.

FAQs

Is your audio sent anywhere?

No. The server only forwards your audio data to devices on your local network that are connected to it. Your audio isn’t sent elsewhere.

Can I connect multiple devices?

Yes. You’ll need to purchase Premium on one Android device. After buying Premium, connect that device to the server to enable multi-connection. The multi-device feature stays active until the server is restarted. It also remains unlocked even if the Premium device disconnects, but it will lock again if you stop the server application.

Does performance drop when the app runs in the background?

Some phone manufacturers aggressively optimize battery usage, which can negatively affect long-running apps like AudioRelay.

Why is there a lot of latency with Bluetooth audio devices?

Bluetooth audio typically has inherent delay. You can notice it using a soundboard app or the provided test method. If you don’t feel much lag on YouTube, that’s usually because video apps sync visuals and audio to hide the delay. You can still detect the issue by pausing and resuming a video.

How can I listen to music or calls at the same time as AudioRelay?

By default, AudioRelay will stop streaming whenever another app requests audio playback. This follows Android’s Audio Focus behavior. If you want to override it:

• Open Settings inside the Android app.
• Tap Exclusive aud and disable the behavior.

Note: If you want version-specific details (e.g., current APK version/build), tell me what version info you have and I’ll format it into the same structure.
