SoundWire Server for Windows

Quick summary

SoundWire Server is a lightweight utility that lets you send audio from a computer to Android devices over a local network. It’s designed to be simple to set up, uses minimal system resources, and supports multiple simultaneous receivers with optional low-latency settings.

How the streaming works

• Install the server component on your Windows or Linux machine (it also runs on Raspberry Pi). It registers a virtual audio device so the PC’s output can be captured.
• Run the Android client and connect to the server by entering the server’s IP address or letting the app discover it automatically on the same Wi‑Fi network.
• Audio played on the computer (any player or system sound) is encoded, transmitted across the LAN, and decoded on the Android device in real time.

Typical ways people use it

• Use your phone or tablet as a wireless speaker for movies, music players, or live streams so audio follows right behind the video.
• Turn a spare laptop with microphone into a monitoring device (for example, a baby monitor) and stream its input to a handheld Android device.
• Stream music from applications such as Spotify, iTunes, or web players directly to your mobile device while the computer remains the source.

Compatible systems and device notes

• Works on Windows (both 32- and 64-bit) and various Linux distributions; supported on Raspberry Pi for lightweight or embedded setups.
• Android clients include phones and tablets. Some Android TV installs require sideloading because the app may not meet Play Store criteria for TVs; regular app updates are provided through Google Play where available.
• macOS is not supported by this application.

Getting started — step-by-step

1. Download and install the SoundWire Server on the computer that will act as the audio source.
2. Launch the server and pick the audio input (usually the system’s default multimedia device). The level meter will confirm audio is being captured.
3. Install the SoundWire app on the Android device and open it.
4. Either type the server’s IP into the client or let the client discover the server automatically, then tap Connect.
5. If you have several servers, choose the correct one from the list. Adjust volume and use the onboard equalizer as desired.

Performance and configuration tips

• The app supports Opus compression and lets you adjust buffer size and codec settings; lowering the buffer and changing compression parameters can reduce latency but may increase bandwidth use.
• Use the Pro/advanced mode to set and display precise buffer latency when tight synchronization matters.
• If you experience dropouts, try switching Wi‑Fi bands or moving closer to the router to improve throughput.

Strengths and limitations

• Strengths: easy to set up, minimal CPU/memory footprint, supports multiple clients simultaneously, and offers a no‑ads experience with configurable latency.
• Limitations: no native macOS version; Android TV installs may require sideloading; performance depends on network quality.

Alternatives worth checking out

• AudioRelay — a modern alternative focused on low-latency phone playback.
• Airfoil — another option for routing audio between devices with extended feature sets.
• Stream What You Hear — lightweight streaming utility for PC audio capture.
• Sockso — a media streaming server that can also serve audio to mobile clients.

Final note

If you want a straightforward way to mirror computer audio to one or more Android devices over Wi‑Fi, this tool is a practical choice: install the server and client, tweak a few settings if needed, and you’ll be streaming audio in minutes.
