⚠️ Important Requirements

This app requires a virtual audio cable device to work!

AndroidMic streams audio from your phone to your PC, but your PC needs a way to recognize this audio stream as a microphone input. This is where virtual audio cables come in.

Virtual Audio Cable Setup

On Windows:

Install Virtual Audio Cable (VAC) or VB Cable (both free options available)
These tools create virtual audio devices on your system
Once installed, you'll have a virtual output device (speaker/playback) and a virtual input device (microphone)
AndroidMic plays audio to the virtual output, which is internally wired to the virtual input that your apps can use as a microphone

On Linux:

Use PulseAudio or PipeWire to create virtual audio devices

Example with PulseAudio:

bash
pactl load-module module-null-sink sink_name=virtual_mic
pactl load-module module-remap-source master=virtual_mic.monitor source_name=virtual_mic_source

On macOS:

Use BlackHole or similar virtual audio driver

Setup Guide

Step 1: Install Virtual Audio Cable

Follow the instructions above for your operating system to install a virtual audio cable solution. This step is required before proceeding.

Step 2: PC Application Setup

Download and install
- Get the latest release from the releases page
- Install and launch the app
macOS users: You may need to run this command to allow the app to run:
```
sh
xattr -c /Applications/AndroidMic.app
```
See this discussion for more details.
Select output audio device
- Choose the virtual output device (e.g., "VB Cable Input" or "Virtual Audio Cable") from the dropdown
- This is the playback device that's wired to your virtual microphone
- Do NOT select your regular speakers or headphones
- On Linux change channel count to "Mono" when you select PipeWire or PulseAudio
Choose connection method
- TCP/UDP (WiFi):
  - Connect your phone and PC to the same network
  - No additional setup required
- USB ADB:
  - Install Android Debug Bridge (ADB)
  - Enable USB debugging on your phone (Developer Options)
  - Connect phone via USB cable
- USB Serial:
  - Connect phone via USB cable
  - Set phone's USB mode to "Charging only"
  - Windows:
    - Close Android Studio and ensure ADB process is not running
    - Your phone must use the WinUSB driver (required for all Android phones)
    - Use Zadig to replace the current USB driver with WinUSB if needed
    - On first connection attempt, the phone will switch to accessory mode - click Connect again to establish the connection
  - Linux: Configure udev rules for USB permissions
Configure audio settings (Advanced)
- Click to open advanced settings
- Choose format supported by your virtual audio device
- Common settings: 44.1kHz or 48kHz sample rate, mono channel, 16-bit or 24-bit depth

Step 3: Android Application Setup

Install the app
- Download the APK from releases or F-Droid
- Install and open the app
Configure settings
- Open the side drawer menu
- Select the same connection method chosen on PC
- Configure audio settings (sample rate, channels, bit depth) - these can be adjusted independently from PC settings
Connect and start
- Grant required permissions:
  - Microphone: To access your phone's mic
  - Notification: To show recording status in background
- Start recording
- Connect to PC:
  - TCP/UDP: Enter PC IP address and port (shown in PC app log)
  - USB ADB: Just click connect
  - USB Serial: Allow accessory mode when prompted

Using AndroidMic in Other Apps

After setup, the virtual microphone will appear in your system's audio input devices. Select it in any application:

Discord, Teams, Zoom (voice chat)
OBS, Streamlabs (streaming)
Audacity, FL Studio (recording)
Any other app that accepts microphone input

Troubleshooting

Can't hear audio / No microphone detected

Verify virtual audio cable is properly installed
Ensure you selected the virtual output device in AndroidMic PC app
Check that applications are using the virtual input device as microphone
On Windows: Check that VAC/VB Cable devices are set as default in Sound Settings

Windows Defender flags the app as malware

Usually this is a false positive due to Windows Defender's ML algorithm
Please report to Microsoft to help get it fixed

USB connection not working

USB ADB: Ensure USB debugging is enabled and ADB is installed
USB Serial: May need Zadig to change USB driver to WinUSB
USB Serial (Linux): Configure udev rules for USB permissions

Audio quality issues

Match audio settings between PC and Android app exactly
Try different sample rates (44.1kHz or 48kHz)
Turn on/off noise cancellation in the app

Project History

The PC app originally started as a WPF application written in C# for Windows only. Most features have been recreated in Rust (thanks to @wiiznokes) for cross-platform support. The WPF app branch is still available for reference.

Note: Bluetooth support was removed in favor of USB Serial connection, which provides better bandwidth.
