Windows installation and virtual microphone output have been tested with iPhone/Safari. Linux and macOS builds pass CI; audio routing on real hardware still needs validation. Android capture also needs device testing. Release notes and checksums
A few things to know.
Do I need a phone app?
No separate mobile app. Micbridge serves the microphone page from your desktop. Open that local link in your phone’s browser, or add it to your home screen.
Can I use it in a meeting or recording app?
Yes. The Windows installer includes optional signed VB-CABLE setup. Click “Enable Micbridge microphone”, then select “Micbridge Microphone (VB-Audio Virtual Cable)” in your meeting or recording app. Existing cables may retain the name “CABLE Output”. macOS requires a virtual audio device; Linux offers a PulseAudio/PipeWire-compatible route. These two desktop routes still need hardware validation.
Why is there a certificate setup step?
Phone browsers require trusted HTTPS to access the microphone. The desktop creates a local certificate, and its setup page walks you through trusting it. On iPhone, installing the profile and enabling full trust are separate steps. See the setup guide.
Will it work with my phone locked?
Keep your phone’s screen awake and the microphone page visible. Safari can suspend audio when the phone locks or the web app is backgrounded. Reliable locked-screen capture would require a native mobile companion.
Where does my audio go?
Between your phone and desktop on the local network. Micbridge has no account system, telemetry, or cloud audio upload. WAV files are saved on your desktop only when you choose to record.
Is it free for commercial use?
Yes. Micbridge is MIT licensed, including commercial use. Preserve the copyright and license notice when distributing it. Third-party dependencies retain their own licenses.
