Hybrid Wi-Fi Audio Streamer (Android)

A high-performance Android application that streams high-quality audio (Movies, Games, Music) in real-time over local Wi-Fi to other Android devices and Web Browsers.

• Zero-Lag Android Streaming: Uses a custom Raw TCP socket protocol (~44.1kHz 16-bit PCM) for ultra-low latency playback on the Android "Listener" app.
• Browser Compatibility: Parallel HTTP Server that keeps a connection open, streaming infinite WAV audio to any web browser (Chrome, Firefox, Safari) without installing an app.
• Internal System Audio: Capture internal device audio (requires Android 10+ and Permission) for streaming movies and games.
• Microphone Support: Fallback to microphone capture for voice or external sounds.
• Local Wi-Fi Only: Fully offline; no internet or external servers required.

The "Host" device runs two parallel servers:

1. Port 50005 (Raw TCP): Optimized for the Android client app. No buffering, raw PCM data.
2. Port 8080 (HTTP): Serves a standard WAV header followed by a continuous stream of PCM bytes. Works with <audio> tags in browsers.

1. Silent Movie Night: Stream your TV/Tablet audio to your phone + headphones so you don't wake the house.
2. Multi-Room Music: Turn old phones into wireless speakers.
3. PC/Console Audio: Use an Android device to capture audio from a specific source.

• Android Studio Hedgehog or newer.
• Android SDK API 34.
• Two Android devices OR one Android device + a PC/Laptop on the same Wi-Fi network.
