How to Use WO Mic on Discord (Windows 10 & 11 Setup Guide)

If your headset microphone broke before a raid or a voice call, WO Mic lets you turn any Android phone or iPhone into a low-latency microphone for Discord on Windows. Because WO Mic installs a kernel-level virtual recording device (WO Mic Virtual Device), Discord treats your phone like a physical USB microphone.

Step 1: Connect WO Mic Before Launching Discord

Discord enumerates audio input devices when it starts. Always establish the WO Mic connection first so the virtual device is active:

1. Install and open the WO Mic Windows Client on your PC and the mobile app on your Android phone or iPhone.
2. Select your transport: USB gives the lowest latency (18–30 ms) for competitive gaming, while 5 GHz Wi-Fi (35–80 ms) works well for casual voice channels. Avoid Bluetooth for Discord if possible — Bluetooth SCO adds 120–220 ms of delay.
3. Click Connection → Connect in the PC client and verify the status bar reads Connected.

Step 2: Select WO Mic Inside Discord Voice Settings

1. Open Discord and click the gear icon (User Settings) next to your username.
2. Navigate to App Settings → Voice & Video.
3. Under Input Device, change Default to Microphone (WO Mic Device). Explicitly selecting the device prevents Discord from switching back to a webcam or monitor microphone after a Windows update.
4. Click Let’s Check under Mic Test and speak into your phone held 15–20 cm from your mouth.

Step 3: Optimal Discord Voice Processing Settings for Phone Mics

Phone microphones have higher sensitivity than dynamic desk mics and pick up room reflections easily. Use this tested configuration inside Discord’s Voice & Video tab to eliminate robotic artifacts and keyboard clicks:

Discord Setting	Recommended Value	Why It Matters
Input Sensitivity	Manual: −55 dB to −48 dB	Auto-sensitivity clips the first syllable over Wi-Fi
Noise Suppression	Krisp (ON)	Filters PC fan hum and mechanical keyboard noise
Echo Cancellation	ON (if using speakers) / OFF (with headphones)	Prevents double compression when you wear headphones
Automatic Gain Control	OFF	Stops Discord from boosting background hiss during silence
Audio Subsystem	Standard	Best compatibility with the WO Mic WDM virtual driver

Troubleshooting Discord + WO Mic Issues

• Discord shows “No Input Detected” even though WO Mic says Connected: Open Windows Settings → Privacy & security → Microphone and confirm both Let apps access your microphone and Let desktop apps access your microphone are enabled.
• Voice sounds robotic after 10 minutes: Android is throttling Wi-Fi when the phone screen turns off. Exclude WO Mic from battery optimization and switch to a USB cable or 5 GHz Wi-Fi. See our full WO Mic troubleshooting guide.
• High ping or voice lag in game: Switch transport from Wi-Fi to USB with USB Debugging. USB uses local ADB port forwarding and never touches your router.
