Micbridge v0.4.0 — Windows virtual microphone

Micbridge 0.4.0 — Windows virtual microphone setup

The Windows x64 installer now bundles the Microsoft-signed base VB-CABLE driver
with an optional setup page, VB-Audio attribution, donation links, and licensing
information. No Windows test-signing is required.

Complete the official VB-Audio setup when prompted, restart Windows, then click
Enable Micbridge microphone. A fresh installation receives the display name
Micbridge Microphone (VB-Audio Virtual Cable). Existing installations retain their names;
select their recording endpoint, usually CABLE Output, in the consuming app.
An optional rename button is available in Micbridge. The shared VB-CABLE remains
installed when Micbridge is removed.

Setup preserves available speaker/microphone defaults when the new cable replaces
them. Check your Windows sound settings after restarting. The official setup and
driver package are preserved unchanged with their original publisher signatures.

Validation includes 14 application tests, Windows app installation/uninstall,
fresh signed driver installation, endpoint naming, existing-driver reuse, and a
real 48 kHz stereo tone recorded through the cable on a disposable Windows runner.
The Windows installation and phone-to-virtual-microphone path have also been
confirmed on the maintainer's PC. Broader Windows 10/11 hardware testing remains
ongoing.

The desktop app also includes setup/retry buttons and a Start menu setup shortcut.
Automatic routing targets the base CABLE Input, with silence during switching and
no intentional fallback to default speakers when the virtual device is missing.

VB-CABLE retains its own donationware terms. Professional/organizational use may
require a paid VB-Audio license. Micbridge remains MIT, copyright Iñaki Abadia.
The Microsoft-signed driver does not sign the Micbridge app: the app and its setup
remain unsigned and may receive Windows SmartScreen warnings. macOS builds remain
unnotarized. Linux/macOS hardware routing and Android capture remain unverified.

On iPhone/Safari, keep the phone page visible and the screen awake. Pair once and
follow the desktop's HTTPS certificate setup instructions.

Micbridge v0.3.1 — preview

Micbridge 0.3.1 — independent desktop preview

Micbridge uses independent virtual audio routes. The legacy native adapter and its bundled .NET helper have been removed from source, runtime, installers, and CI.

Downloads

• Windows x64 setup wizard and portable EXE.
• Linux x64 AppImage and Debian package.
• macOS Apple Silicon (arm64) and Intel (x64) DMGs.
• Per-platform license notices and combined SHA256SUMS.txt.

The Windows setup wizard supports current-user or all-users installation, a custom destination, desktop/Start menu shortcuts, and uninstall. CI checks silent current-user installation and uninstall. Interactive wizard navigation and all-users elevation still need manual validation.

Changes

• Independent Windows audio routing through Desktop output and an externally installed virtual audio cable. No other phone microphone application is required.
• Linux keeps its PulseAudio/PipeWire-compatible virtual microphone route. macOS routes through an independently installed virtual audio device.
• New animated GitHub Pages homepage with setup guidance, downloads, and honest platform limitations.
• No .NET SDK or bundled native helper is needed to build Micbridge.

Preview limitations

The packages are unsigned; macOS packages are unnotarized. Hardware audio routing on Linux/macOS, Android capture, and fresh-machine conferencing compatibility still need validation. A Micbridge-owned Windows virtual microphone driver is not implemented: monitoring and recording work without a virtual device, but other applications need an independent virtual audio cable.

Safari can interrupt recording when the phone locks or the browser moves into the background. Keep the phone page visible and the screen awake. Follow the desktop's local HTTPS certificate setup and pair once using its six-digit code.

Micbridge 0.3.0 — early preview

Archived release: downloads have been withdrawn. Use Micbridge 0.4.0. The historical feature notes below do not describe the current release.

Micbridge 0.3.0 — early preview

Historical notes: the device adapter described below was removed in v0.3.1. Use v0.3.1 or later for an independent build.

Turn your phone into a microphone for your desktop over your local network.

Downloads

• Micbridge-0.3.0-windows-x64.exe: portable Windows x64 desktop. Download and run; no separate phone app is required.
• Micbridge-0.3.0-notices.zip: MIT license, dependency inventory, and third-party license texts. These are also included inside the portable application's resources.
• SHA256SUMS.txt: checksums for the executable and notices archive. On Windows, compare with Get-FileHash -Algorithm SHA256.

Included

• Browser microphone capture and desktop audio monitoring, gain, mute, and WAV recording.
• Fixed HTTPS port 8443 and a clean /phone URL suitable for bookmarking or adding to the iPhone home screen.
• One-time pairing codes with persistent secure cookies; paired phones can be revoked from the desktop.
• Local certificate setup with an iPhone installation profile and trust instructions.
• Integrated desktop window controls, tray icon, and original Micbridge branding.

Getting started

Run the desktop on the same local network as your phone. Follow its certificate setup instructions, open the phone URL, pair using the desktop code, and start the microphone. Use headphones when enabling desktop monitoring to avoid feedback.

Preview limitations

• This Windows build is unsigned. Windows may display a SmartScreen warning.
• Windows monitoring with iPhone/Safari has been tested. Fresh-machine setup and virtual microphone consumption by conferencing apps still need validation.
• Safari may stop microphone streaming when the phone locks or the web app moves into the background. Keep the app visible and the screen awake.
• Windows virtual microphone routing requires a separately installed virtual audio cable or another compatible virtual audio device. The included independent user-mode adapter supplies no proprietary kernel driver and does not install one.
• Linux and macOS source support is included, but downloadable binaries and hardware audio routing validation are not part of this release.
• Neural noise reduction and compressed WebRTC/Opus transmission are not implemented. Browser audio processing is used where supported.

Audio stays on your local network. Recordings are saved locally when requested. The application is released under MIT, copyright 2026 Iñaki Abadia; dependencies retain their own licenses.
