How to set up your microphone

Complete guide to connecting, installing, and configuring your microphone. Covers USB, XLR, and analog microphones on Windows, macOS, and Linux.

Whether you have a USB microphone, XLR setup, or simple analog mic, this guide will help you get it working and sounding great on any operating system.

Connection types

USB microphones are the easiest to set up — they include a built-in sound card:

Plug the USB cable into an available USB port (USB 3.0 recommended for lower latency)
Wait for your operating system to detect and install the device
Select the microphone as your input device in system settings

Tip: Connect directly to your computer, not through a USB hub, to avoid potential audio issues and latency.

XLR microphones need an audio interface to connect to your computer:

Connect your audio interface to your computer via USB
Install audio interface drivers if required (check manufacturer website)
Connect the XLR cable from your microphone to the interface input
Turn on phantom power (48V) if using a condenser microphone
Set the interface as your audio input device in system settings

Popular interfaces: Focusrite Scarlett series, PreSonus AudioBox, MOTU M2, Universal Audio Volt

Analog microphones connect to the pink 3.5mm microphone jack on your computer:

Locate the microphone input (pink jack, often marked with a mic icon) — not the headphone output (green)
Plug in the microphone connector
The system should detect it automatically

Note: Audio quality depends on your computer's built-in sound card. For better quality, consider a USB microphone or external audio interface.

Headsets can connect via USB, 3.5mm, or both:

USB headset: Plug in and select as input/output device
Single 3.5mm (TRRS): Use the combo jack on laptops, or a splitter for separate mic/headphone jacks
Dual 3.5mm: Pink plug to mic input, green plug to headphone output

Driver installation

Windows 10/11 automatically installs drivers for most USB microphones:

Connect your microphone
Wait for the "Setting up device" notification
Once complete, the mic appears in Sound settings

To verify: Right-click the speaker icon → Sound settings → Input and check that your microphone appears.

macOS has built-in support for most USB microphones through the USB Audio Class standard. Simply plug in and it should work immediately.

To verify: System Settings → Sound → Input tab and select your microphone.

Most USB microphones work out of the box with PulseAudio or PipeWire:

# List audio input devices
pactl list sources short

# Set default input device
pactl set-default-source <source-name>

# Test recording
arecord -d 5 test.wav && aplay test.wav

Some devices, especially audio interfaces, require manufacturer drivers:

Visit the manufacturer's website (Focusrite, PreSonus, MOTU, etc.)
Download the latest driver for your operating system
Run the installer and follow instructions
Restart your computer if prompted
Connect your device and verify it appears in sound settings

Note: Always download drivers from the official manufacturer website, not third-party sources.

System configuration

Windows 11:

Right-click the speaker icon in the taskbar
Select Sound settings
Under Input, click the dropdown and select your microphone
Speak into the mic — you should see the volume bar respond

Windows 10:

Right-click the speaker icon → Open Sound settings
Under Input, choose your microphone from the dropdown
Click Device properties for additional settings

Open System Settings (or System Preferences on older versions)
Go to Sound
Click the Input tab
Select your microphone from the list
Adjust the input volume slider while speaking to set the level

Tip: Option-click the Sound icon in the menu bar to quickly switch input devices.

Using PulseAudio/PipeWire:

Open Sound Settings or pavucontrol
Go to the Input Devices tab
Find your microphone and click the checkmark to set as default
Adjust the volume slider as needed

# Or via command line
pactl set-default-source <source-name>
pactl set-source-volume @DEFAULT_SOURCE@ 80%

Proper input level is crucial for good audio quality:

Too low: Your voice will be quiet with audible noise when amplified
Too high: Audio will clip (distort) on loud sounds
Ideal: Peaks at about 70-80% when speaking at normal volume

Tip: Speak at your normal volume and adjust until the meter peaks in the upper third without hitting the maximum. Leave headroom for louder moments.

Access advanced microphone settings:

Right-click speaker icon → Sound settings
Click More sound settings (or Sound Control Panel)
Go to Recording tab, double-click your microphone
Levels tab: Adjust volume and microphone boost (+10/+20 dB if too quiet)
Enhancements tab: Enable noise suppression, acoustic echo cancellation if available
Advanced tab: Set sample rate (44100 Hz or 48000 Hz recommended)

macOS provides basic input controls in System Settings. For advanced features, use the Audio MIDI Setup app:

Open Audio MIDI Setup (search in Spotlight)
Select your microphone in the left sidebar
Adjust format (sample rate) and input channels

Note: For noise reduction and enhancements, use third-party apps like Krisp or your DAW software.

Use pavucontrol for GUI or command line:

# Install pavucontrol for GUI control
sudo apt install pavucontrol

# Adjust volume via CLI (100% = 0dB, 150% = boost)
pactl set-source-volume @DEFAULT_SOURCE@ 100%

# Enable echo cancellation module
pactl load-module module-echo-cancel source_name=noechosource

Positioning and technique

Distance: 4-8 inches (10-20 cm) from your mouth for most microphones. Dynamic mics can be closer (2-4 inches).
Angle: Slightly off-axis (not directly in front of your mouth) reduces plosives (p, b sounds)
Height: Position at or slightly below mouth level, angled up toward your mouth
Consistency: Maintain the same distance throughout your session

Tip: A boom arm allows precise positioning and keeps the mic off your desk, reducing vibration noise.

Close windows and doors to reduce outside noise
Turn off fans, AC units during recording if possible
Use a cardioid microphone and position it away from noise sources
Add soft furnishings — rugs, curtains, and furniture absorb echo
Enable software noise suppression — RTX Voice, Krisp, or built-in filters

Troubleshooting

Try a different USB port (directly on motherboard, not hub)
Open Device Manager and look for unknown devices or warning icons
Right-click the device and select "Update driver"
Check Sound settings → More sound settings → Recording tab — right-click and enable "Show Disabled Devices"
Restart Windows Audio service (services.msc)

Try a different USB port or remove USB hubs
Check System Information → USB to see if the device is detected
Reset Core Audio: sudo killall coreaudiod
Reset NVRAM/PRAM (Intel) or restart (Apple Silicon)
Check for manufacturer-specific drivers

Check if device is detected: lsusb and arecord -l
Restart PulseAudio: pulseaudio -k && pulseaudio --start
Check if your user is in audio group: groups $USER
View system logs: dmesg | grep -i audio

Enable microphone boost in sound settings (+10 or +20 dB)
Move closer to the microphone — 2-4 inches for dynamic mics
Check gain on audio interface if using XLR
Verify phantom power is on for condenser mics (48V)
Check the cable — try a different XLR or USB cable

Lower the input gain — you're likely overloading the input
Increase distance from the microphone
Check for USB bandwidth issues — try a different port
Disable microphone boost if enabled
Update audio drivers to latest version

Use headphones instead of speakers to prevent mic picking up output
Disable "Listen to this device" in microphone properties (Windows)
Enable echo cancellation in your app or system settings
Lower speaker volume if you must use speakers
Check for monitoring enabled in your audio interface software
