AudioRelay for Windows 7: The Ultimate Guide to Streaming Audio from Legacy PCs Introduction: Breathing New Life into Windows 7 with AudioRelay Windows 7 may have reached its End of Life (EOL) in January 2020, but millions of users still rely on this stable, lightweight operating system for legacy hardware, audio production, or industrial use. One of the biggest challenges for these users is modern connectivity—specifically, how to stream low-latency audio from an old Windows 7 machine to modern smartphones, speakers, or other computers. Enter AudioRelay . This powerful, free (and open-source) utility allows you to stream any audio from your Windows 7 PC over a local Wi-Fi or Ethernet network to an Android or iOS device. Whether you want to use your phone as a wireless headset, turn an old tablet into a remote speaker, or monitor system sound from another room, AudioRelay is the solution. But does AudioRelay work on Windows 7? Yes—with a few important caveats. This article will walk you through everything: installation, setup, troubleshooting legacy drivers, and optimizing performance for Windows 7.
What is AudioRelay? A Brief Overview AudioRelay is a cross-platform audio streaming application. It consists of two components:
The Server (this runs on your Windows 7 PC): Captures the system audio output (or microphone input) and sends it over your network. The Client (Android / iOS / Another PC): Receives the stream and plays it through the device's speakers or headphones.
Unlike Bluetooth, which introduces significant lag and compression, AudioRelay uses OPUS codec over UDP, achieving latencies as low as 10-50 milliseconds on a good network. This makes it viable for watching movies, gaming, or monitoring DAW (Digital Audio Workstation) outputs. Key Features for Windows 7 Users: audiorelay windows 7
Low latency (adjustable buffer size). High audio quality (up to 48000 Hz stereo). Supports both output streaming (PC sound to phone) and input streaming (phone mic to PC). No cloud servers —everything stays on your local network. Completely free with no ads (donation-ware).
System Requirements: Can Your Windows 7 PC Run AudioRelay? Before downloading, verify your specs. AudioRelay is lightweight, but Windows 7’s older audio stack can be a hurdle. Minimum Requirements:

Step 2: Install Required Windows 7 Runtimes AudioRelay depends on modern C++ redistributables. Windows 7 does not include these by default.
Download and install Visual C++ Redistributable for Visual Studio 2015-2022 (x64 and x86 both). Install KB2670838 – this is the Platform Update for Windows 7 that adds improved DirectX and audio APIs. Without it, AudioRelay will crash on startup.
