🔧 How it works

1. Audio Input: VoxShare captures audio from the selected microphone in real-time.
2. Push-to-Talk: Audio is transmitted only while the push-to-talk button (space) is held down.
3. Multicast UDP: Audio packets are sent over a multicast UDP channel to all clients in the local network.
4. Volume Meter: A volume meter displays your current speaking volume.
5. Audio Output: Received audio packets are played through the selected output device.
6. Client Discovery: Clients periodically broadcast small PING packets to detect active peers.
