PhoneMic
Use your iPhone as a wireless microphone for your Windows PC. Free, works over your own Wi-Fi, nothing leaves your network.
Setup
- Run PhoneMicSetup.exe. Leave "Start PhoneMic at login" ticked.
- Install VB-CABLE (free virtual audio cable — the installer points you there if it's missing), then reboot once.
- Open the PhoneMic app on your iPhone, pick your PC from the list, and start streaming.
- In Zoom, Discord, or any app, choose "CABLE Output (VB-Audio Virtual Cable)" as your microphone.
Phone and PC must be on the same Wi-Fi / LAN. If Windows asks about network access on first run, allow it for private networks.
