Functions of AudioRelay:

Real‑time PC audio to your phone: AudioRelay lets you stream any PC audio to your Android phone over Wi‑Fi or via USB. The connection is designed for low delay, so music, movies, and games feel responsive. You select the source on the desktop app, then listen on your phone as if it were a wireless speaker. This makes the AudioRelay app useful when your computer speakers are broken or you want sound in another room.

Route phone audio back to the computer or another Android: AudioRelay supports routing your phone’s audio back to the PC for recording or monitoring. You can also share audio to another Android device, which helps in basic monitoring or quick listening setups. This routing option is helpful when testing a source, tracking a recording, or sharing audio in a nearby space. It keeps the workflow simple while avoiding extra cables.

Quick setup with desktop companion and stable connections: AudioRelay pairs with a desktop app that works across Windows, macOS, and Linux. You connect over Wi‑Fi for convenience or use USB tethering to cut down on lag and dropouts. USB is the better choice when you need tighter timing, such as gaming or live monitoring.

FAQs of AudioRelay:

How to improve audio quality?

To reduce latency, AudioRelay sends the audio data on your device's "fast path". But on some devices, this results in a quality loss. (Confirmed on Xiaomi phones)

To fix this, try the AudioTrack output in the Android app settings. Note that this could increase the audio latency.

Inside the Android app, go to settings

Audio output

Select AudioTrack

Uncheck low latency

Otherwise, check that Windows is emitting the sound to a format of at least 48kHz

Type sound settings in the Windows search bar

Device properties

Click on Additional properties at the bottom

Advanced

Change the default format

Why is the volume so low?

The audio's volume received by AudioRelay can sometimes be tied to the volume of your PC.Try to increase the volume in Windows before muting your PC.

Why is there a lot of latency when listening through a Bluetooth device?

Unfortunately, audio played over Bluetooth is inherently going to have latency. You can observe the delay of your headset by playing with a soundboard app, or using this one.If you don't notice any latency when using YouTube, it's because videos apps can compensate for the lag by synchronizing both the image and the audio. You can still notice the audio delay by pausing and resuming a video.

Is your audio sent anywhere?

The server only sends your audio data on your network to your connected devices. It's not sent anywhere else.

Conclusion:

AudioRelay can give a second life to any old Android device you have lying around your home. All you have to do is install the app, connect the device to your PC using a USB cable, and just like that, you'll have a fully functional microphone or new speaker. It's that easy.
