WiFi Audio Streaming is a versatile Android application that allows you to stream audio over your local network. It works as a multi-protocol audio hub: act as a server to capture and send your Android device's audio, or as a client to receive and play audio from another device. With support for standard protocols, you can even stream directly to a web browser or media player.

Key Features:

• Multi-Protocol Architecture: Stream using the native low-latency protocol (WFAS v2, now an open, documented specification), standard RTP for media players, or HTTP to listen directly from any web browser (Chrome, Safari, Smart TVs).
• Password Protection & Encryption: Control exactly who can connect with Off, Ask, or Key authorization modes, and optionally encrypt the whole stream end-to-end with ChaCha20-Poly1305.
• Internal Audio Streaming: In Server mode, stream your device's internal audio (apps, games, music) to other devices (requires Android 10+).
• Smart Auto-Connect: Automatically connect to prioritized IP addresses as soon as they are detected on the network, even in the background.
• Automation Ready: Trigger the app with shortcuts, deep links, or NFC tags, and save full server/client configurations as one-tap presets.
• Widgets & Quick Settings: Control your server or client directly from your home screen using interactive widgets, or use the Quick Settings tiles for instant access.
• Automatic & Manual Discovery: Clients automatically find available servers on the local network via a lightweight UDP discovery beacon. Manual IP connections automatically detect if the host is using Unicast or Multicast.
• Unicast & Multicast Support: Stream directly to a single device (Unicast) or to multiple clients simultaneously (Multicast), ideal for multi-room setups.
• Advanced Configuration: Customize sample rate, channels, buffer size, latency and payload size, and manually select your active network interface to bypass VPN routing issues.
• Modern Interface: Rebuilt from the ground up with Jetpack Compose and a full Material 3 Expressive redesign, with dynamic colors and a dedicated Dark Screen mode for OLED displays.

The project is also available for Windows and Linux! Turn your computer into a wireless audio transmitter, receiver, or web server. Find the desktop version at GitHub and at GitLab.

The WFAS wire protocol is fully documented and comes with an open-source, dependency-free C99 reference implementation for embedded and firmware projects (ESP32, STM32, RP2040, and more). Find it at GitHub.
