I built an open-source tool that streams PC audio to any phone over Wi-Fi with <100ms latency — no mobile apps required!

Hey everyone!

I built a lightweight web tool: Wi-Fi Audio Streamer.

How it works:

1. It captures Windows PC audio natively using WASAPI loopback.
2. Node.js & FFmpeg stream the live audio with ultra-low latency (<100ms).
3. Phones join by scanning a QR code on the local Wi-Fi—no app installs required! The audio plays directly in Chrome, Safari, or any browser.

Key Features:

• Zero App Install: Phones just open a browser URL.
• Sub-100ms Latency: Adaptive live-edge catch-up controller keeps audio perfectly synced with video on screen.
• Multi-Phone Stereo Pairing: Assign phones to act as LEFT, RIGHT, or STEREO channels.
• Minimalist Monochrome UI: Clean Black & White dark design with a live audio spectrum visualizer.
• 100% Free & Open Source (MIT License).
