Security

Safe initial state

• Launching alone captures nothing
• AI audio starts OFF in listen-only
• The physical microphone and AI gate are independent
• Kill immediately stops AI without dropping the microphone

Speak once

The gate does not open until AI audio actually begins. Start wait, silence grace, and maximum transmit time are bounded, and completion returns the gate to OFF.

Stop and restore

MCP EOF, cancellation, Stop, and app termination close AI audio and destroy temporary taps and aggregate devices. If the app changed the default input, it restores the previous input when possible.

Drivers

Persistent public inputs are user-space AudioServerPlugIns, not kernel extensions. Initial installation and updates require administrator approval.

Report a vulnerability

For sensitive audio, gate, signing, or installer findings, do not post confidential details publicly. Email info@brainfiber.net with the subject “Viyv Meeting Bridge Security”.
