Modern smartphones are equipped with high-quality microphones, often outperforming those built into budget webcams and cheap headsets. Using a mobile device as a computer microphone is a practical solution for those looking to improve audio quality during streaming, video calls, or podcast recordings without breaking the bank.
The most convenient way to implement this idea is to use technology WO Mic (Wireless Microphone), which allows you to stream audio from your phone to your PC. Unlike wired solutions, a wireless connection allows for freedom of movement and eliminates unnecessary cables from your workspace, which is especially important for compact setups.
In this guide, we'll cover software installation, router configuration, and optimization to minimize audio latency. You'll learn how to ensure a stable connection and what nuances to consider when working on a local network.
How wireless connection works and its advantages
WO Mic technology is based on real-time audio data transmission over a local network. A smartphone app captures the audio, compresses it into a stream, and sends it to the client software installed on the computer. WiFi connection In this case, it acts as a virtual cable, providing the high bandwidth necessary for transmitting high-quality audio.
The main advantage of using WiFi The advantage of Bluetooth is significantly lower latency and higher signal quality. Bluetooth often compresses audio more heavily and can have noticeable lag, which is critical for synchronous recording or live communication. Furthermore, the Wi-Fi range allows you to move several meters away from your computer without losing connection.
However, it's important to keep in mind that stability directly depends on the quality of your wireless network. If the router is overloaded or the signal is weak, you may experience interruptions. Therefore, before beginning setup, make sure your smartphone and computer are on the same subnet and use the same router.
⚠️ Note: Using public WiFi networks (such as cafes and airports) to connect WO Mic is not possible due to security restrictions that block a direct connection between devices. Use only a home or office network where you control the router settings.
The system doesn't require complex networking equipment. It's enough for both devices to support the standard. 802.11n or newer. This ensures sufficient data transfer speed for lossless audio formats.
Preparation of equipment and installation of the client part
The first step in the setup process is preparing the software on your computer. You'll need to download and install the WO Mic client from the developer's official website. It's important to download the latest version, as older releases may not support new encryption protocols or codecs.
After downloading the installation file, run the installer. During the installation process, the system will ask for permission to install the virtual device drivers. This is a critical step: without correctly installed drivers The computer will not recognize the phone as an audio input device.
During installation, you will be asked to select the driver type. It is recommended to select the option WO Mic Device, as it provides the best compatibility with most Windows operating systems. If you're using Linux or macOS, the process may differ and require manual configuration of ALSA or CoreAudio, respectively.
- 📥 Download the WO Mic Client installer from the developer's official website.
- ⚙️ Run the installation and wait until the files are copied.
- 🔄 Restart your computer to activate virtual drivers.
- 🔌 Make sure your antivirus software isn't blocking the program's network component.
After rebooting, check if the new device appears in the Windows list of sound devices. It may appear as "WO Mic Device" or "Microphone (WO Mic Device)." If the device is visible but marked with an error, try reinstalling the drivers through Device Manager.
Setting up the app on your smartphone
The next step is to install the mobile app. Open the Google Play Store on your Android device or the App Store on your iPhone and search for "WO Mic." Make sure the developer is listed as "WO Mic Team" to avoid installing fake apps with adware.
After installation, launch the app. When you first launch it, it will ask for permission to access your microphone. Permission It's mandatory to provide this information, otherwise audio transmission will be impossible. The app's interface is minimalist and contains basic connection settings.
In the main menu, click the settings icon (usually a gear) or the "Connect" button. Here you need to select a connection method. For our purposes, we'll select WiFiSome versions of the app may require you to manually enter your computer's IP address, but most often, the app automatically detects or displays your phone's IP address for input on your PC.
Please pay attention to the connection port. The default port is 18006If this port is occupied by another program or blocked by a firewall, you can change it in the application settings to any free one, for example, 18007The main thing is that the ports on the phone and in the PC client match.
The process of pairing devices via a local network
Now let's move on to the actual connection. Make sure your smartphone and computer are connected. the same WiFi networkThis is a fundamental requirement: if the phone is connected via mobile internet (4G/5G) and the PC is connected via WiFi, the connection will not be established.
Launch the WO Mic app on your smartphone and press the "Start" button (usually the red button at the bottom of the screen). The phone screen will display the device's IP address on the local network, for example, 192.168.1.45Write down this address or leave the screen on.
Go to your computer. Open the WO Mic client program. In the menu Connection select WiFiIn the "IP Address" field, enter the address displayed on your phone's screen. Make sure the port is correct (default is 18006). Click the button Connect.
Example of connection settings:IP Address: 192.168.1.XX
Port: 18006
Transport: UDP (recommended for speed) or TCP (for stability)
If the connection is successful, the indicator in the client will turn green, and "Connected" will appear on your phone. Now the audio from your phone's microphone is streaming to your computer. All you need to do is select WO Mic as the default recording device in Windows sound settings or in a specific application (Skype, Discord, OBS).
☑️ Connection checklist
Diagnosing problems and optimizing latency
Even with proper setup, audio issues may still occur. The most common user complaint is echo or voice delay. Latency in WiFi networks can vary from 20 to 200 ms. This is acceptable for conversations, but professional recordings may require adjustment.
To reduce latency, try switching the data transfer protocol in the client settings from TCP to UDPThe UDP protocol is less reliable (it doesn't guarantee delivery of every packet), but it's significantly faster, which is critical for real-time audio streaming. Reducing the bitrate in the app settings on your phone also helps.
If the sound is interrupted or stuttering, check the WiFi channel load. Use WiFi analyzer apps to find the least congested frequency. Switch the router to a frequency 5 GHz instead of 2.4 GHz often solves interference problems and improves connection stability.
| Problem | Possible cause | Solution |
|---|---|---|
| No sound | No input device selected | In Windows Sound settings, select WO Mic |
| Severe delay | The TCP protocol is used | Switch to UDP in the client settings |
| Connection error | Blocked by firewall | Add an exception for WO Mic in Firewall |
| A quiet sound | Low level (Gain) | Increase the volume in the Windows mixer |
⚠️ Note: If you're using a third-party antivirus (Kaspersky, ESET, Avast), the built-in Windows firewall may be disabled, but the antivirus's firewall will block the connection. You'll need to add WO Mic to your antivirus's list of trusted programs.
Advanced settings and use in programs
Once the basic connection is set up, you can begin fine-tuning the settings. In Windows, open the Sound Control Panel, find WO Mic, go to Properties, and then the "Enhancements" tab. Here, you can enable noise reduction if the app's built-in algorithms aren't handling background noise.
For streamers and content creators, adjusting levels is essential. In OBS Studio or a similar program, add the "Input Audio Capture" source and select WO Mic. Use noise reduction and compression filters within the recording program to achieve studio-quality audio.
It's possible to use multiple microphones simultaneously. You can combine the WO Mic with a regular microphone, creating a mixer in a Virtual Audio Cable, but this requires more advanced knowledge of Windows audio streaming.
The secret to a stable connection
For maximum stability, secure your smartphone's IP address in your router settings (DHCP Reservation). This will prevent your phone from receiving a new IP address after a router reboot, forcing you to re-enter it in the PC client.
Keep in mind that using WiFi consumes your smartphone's battery. For long sessions, it's recommended to keep your phone charged or use a power bank, especially if you turn off the device's screen to conserve resources.
Frequently Asked Questions (FAQ)
Is it possible to use WO Mic over the internet while in different cities?
The WO Mic's standard WiFi function only works within a single local area network (LAN). Connecting over the internet would require complex port forwarding setup on the router or using a VPN tunnel (such as ZeroTier or Hamachi) to connect the devices into a virtual LAN. A direct IP connection from an external network without port forwarding will not work.
Why does the microphone work in the Windows test, but I can't hear it in Discord?
Most likely, a different default input device is selected in Discord's settings. Go to Discord Settings -> Voice & Video -> Input Device and select "Microphone (WO Mic Device)." Also, check if "Push to Talk" is selected there if you expect it to activate automatically.
Does this app increase my data usage?
When connected via WiFi, traffic goes through your home router and doesn't consume your mobile data. However, the audio stream itself creates a load on the local network. When using the Opus codec, data consumption is minimal (around 20-50 kbps), which is unnoticeable even on weak channels. When choosing PCM, consumption can increase to 1-2 Mbps.
Does WO Mic work on iPhone (iOS)?
Yes, the app is available for iOS. The connection process is identical to the Android version. However, iOS may have stricter restrictions on background app operation. It's recommended to keep the WO Mic app open on your iPhone screen while using it to prevent the system from interrupting audio streaming to save battery life.
How to remove background noise from a computer fan?
WO Mic has built-in noise reduction, but it's basic. For best results, use software solutions like NVIDIA Broadcast (if you have an RTX graphics card) or RTX Voice, which can be overlaid with WO Mic's virtual microphone. Physically positioning your phone away from the system unit will also help reduce noise.
