Hi everyone!
I've created an open-source desktop app called VoxShare — a Push-to-Talk voice communication tool that uses UDP Multicast and the Opus codec for fast and efficient audio streaming over local networks. It’s designed with simplicity and privacy in mind — no servers, no accounts, just instant LAN voice chat.
Key Features:
Real-time audio streaming with Opus codec (via PyOgg)
UDP Multicast — works without centralized servers
️ Modern GUI built with CustomTkinter
Push-to-Talk (PTT) with optional keyboard shortcut
Visual audio level meter
Multiclient audio mixing (each peer is both sender and receiver)
Configurable INI file (with GUI options coming soon)
Nicknames and active speaker display
100% open-source, cross-platform (Windows for now, Linux support in progress)

This project was born out of my personal need for a lightweight, LAN-based voice chat tool, especially for offline setups, local team coordination, or internal networks without access to Discord/Zoom/etc.
Any feedback, testing, suggestions — all are welcome!
Happy to answer any questions or collaborate with others.
