AudioRelay

What if you could turn your Android device into a wireless audio receiver for any PC or laptop?

AudioRelay solves a fundamental connectivity gap: streaming high-quality audio from your computer directly to your Android phone or tablet over your local network. Instead of being tethered to desktop speakers or struggling with Bluetooth range limitations, this app transforms your mobile device into a wireless sound output endpoint. The core utility is straightforward—your phone becomes an extension of your PC's audio system, allowing you to move freely around your home or office while maintaining uninterrupted audio playback from any desktop application.

Core Mechanics and Technical Architecture

The application operates on a client-server model. You install the AudioRelay desktop companion on your Windows, macOS, or Linux machine, which captures system audio and streams it over Wi-Fi or Ethernet to the Android client. The setup process requires no account creation or cloud dependency—both devices simply need to be on the same local network. Once connected, latency remains impressively low, typically under 200 milliseconds, making it viable for video content, live streams, and even casual gaming where audio synchronization matters.

The streaming engine supports multiple codec options, including OPUS for bandwidth-efficient transmission and PCM for uncompressed, studio-grade fidelity. Users can select between mono and stereo output, adjust buffer sizes to optimize for either stability or responsiveness, and configure automatic reconnection if the network temporarily drops. The interface presents a clean connection screen showing discovered servers on the local network, with manual IP entry available for advanced configurations.

Key Advantages and Performance Observations

• Zero-latency wireless audio streaming from any desktop application directly to your Android device over local Wi-Fi or Ethernet networks
• Multi-platform server support with dedicated desktop apps for Windows, macOS, and Linux operating systems
• Customizable audio codec selection between OPUS for efficient streaming or PCM for uncompressed high-fidelity output
• Automatic server discovery on local networks with manual IP configuration for advanced routing scenarios
• Adjustable buffer settings allowing users to prioritize either low-latency response or stable playback performance

The application handles multiple simultaneous connections gracefully, meaning you can stream to several Android devices from one computer if needed. Background playback continues reliably even when the phone screen is off or when switching between other apps. Volume control remains independent between the desktop source and the Android device, giving you granular adjustment without affecting system levels on either side.
