How to Record Audio with a USB Microphone

A USB microphone has its own analog-to-digital converter, so the computer receives a digital signal over the cable and treats the microphone as a separate input device. Recording with it takes three things: the system has to recognize it, your recording app has to use it as the capture source, and the input level has to be set so your voice is clear without distorting.

Before you start

Most USB microphones are class-compliant and work with the standard audio drivers in Windows, macOS and Linux. Some models also come with optional control or mixing software. Check the manufacturer's documentation for your model to see whether it needs anything extra.

The built-in recorders and desktop editors in this guide record to a file on your own device. Browser-based or online recorders may process or upload audio on a remote service. Before using one for private material, check its documentation for where files go and how long they are kept.

• The microphone and the cable that came with it
• A free USB port on the computer
• Headphones for monitoring, so speaker sound does not leak into the recording
• A recording app: a built-in recorder or a desktop audio editor such as Audacity
• Enough free disk space, especially for uncompressed formats
• The quietest room available, with fans and other noise sources switched off where possible

Step-by-step instructions

Before you change anything, note your current default input and output devices so you can switch back afterwards. Everything below is a settings change and can be undone.

1. Connect the microphone and select it as the input device

Plug the microphone in and give the system a moment to detect it. Then select it in the system sound settings. On Windows 11, go to Settings > System > Sound and choose the microphone under Input. On Windows 10, use the input device dropdown on the same Sound page. On macOS Ventura and later, go to System Settings > Sound > Input; earlier versions use System Preferences > Sound > Input. On Linux, the location depends on your desktop's sound settings; PulseAudio Volume Control (pavucontrol) lists inputs on its Input Devices tab. Speak into the microphone and confirm that the level meter moves.

2. Allow microphone access

Windows and macOS block microphone access for apps that have not been given permission. On Windows 11, check Settings > Privacy & security > Microphone. On macOS, check System Settings > Privacy & Security > Microphone and turn on access for your recording app. If an app has no permission, it may record silence even though the microphone is working.

3. Choose the microphone in your recording app

Many apps have their own input setting that can override the system default, so check it in the app too. On Windows 11, the Sound Recorder app lets you pick the recording device in its settings. On Windows 10, the older Voice Recorder uses the system default input. In QuickTime Player on macOS, choose File > New Audio Recording, then use the arrow next to the record button to select the microphone. In Audacity, choose the microphone from the recording device dropdown in the Device Toolbar. You don't need a dedicated USB microphone recorder; any app that lets you choose the input device will work.

4. Set the input level

Speak at the distance and volume you will use for the real recording, and watch the app's meter. Adjust the gain knob on the microphone if it has one; otherwise, adjust the input volume in the system sound settings. Leave headroom so that loud moments never reach the top of the meter. A common target is peaks around -12 to -6 dBFS. A signal that hits maximum clips, and clipping cannot be removed afterwards.

5. Check the sample rate

44.1 kHz and 48 kHz are the usual choices; 48 kHz is the standard for video work. Use the same rate for the device and the project in your app so the audio isn't resampled. On Windows, the device's default format is in the classic Sound control panel: on the Recording tab, open the microphone's Properties and go to the Advanced tab. On macOS, use the Audio MIDI Setup app. Only the rates your microphone supports will be listed.

6. Set up monitoring

If the microphone has a headphone jack, plug your headphones into it. This direct monitoring lets you hear yourself without the delay that software monitoring adds. Otherwise, select your headphones as the output device. Avoid monitoring through speakers, because the microphone will pick up their sound.

7. Record and save

Record a short test, play it back, and only then record the full take. When you export or save, pick the recording format based on what happens next. Lossless formats such as WAV or FLAC keep the full quality for editing. Compressed formats such as MP3 or AAC (M4A) produce much smaller files, and their quality depends on the bitrate. Keeping a lossless original and creating compressed copies from it gives you the most options later.

Check the output

Play the recording through headphones from start to finish. Listen for distortion on loud words, hum or hiss, background noise, clicks or dropouts, and room echo. In an editor that shows a waveform, peaks with flat tops are a sign of clipping.

Then check the file's properties in your editor or file manager: format, sample rate, number of channels, and bitrate or bit depth. Confirm they match what you chose. If the audio plays from only one side, the microphone probably recorded to one channel of a stereo track; convert it to mono or record in mono. If playback sounds sped up or slowed down, check that the project and device sample rates match. Converting a compressed file to WAV does not restore quality lost during encoding.

Common problems and next steps

Microphone not listed: try a different USB port and cable, and connect directly to the computer instead of through an unpowered hub. Many apps only scan for devices when they start, so restart the app after plugging in the microphone. In Audacity, you can use Transport > Rescan Audio Devices instead.

Recording is silent: check the microphone permission for the app, confirm the app is using the USB microphone and not a built-in one, and check whether the microphone has a mute button or a gain knob turned all the way down.

Too quiet or too distant: move closer and raise the gain gradually. Check that you are speaking into the correct side. Many USB microphones are side-address, which means you speak into the side of the body rather than the top. The product documentation shows which way yours faces.

Distorted: lower the gain or move back a little, then make a new recording. Noise reduction will not fix clipping.

Background noise: reduce the source first by switching off fans, moving away from the computer, or recording in a room with soft furnishings. If your microphone has selectable polar patterns, cardioid picks up less sound from the sides and rear. Use noise reduction in an editor as a last step, and apply it lightly.

Hearing a delay or echo while recording: switch from software monitoring to the microphone's headphone jack, or turn off monitoring in the app.

Using the microphone in video calls: call apps have their own microphone and speaker settings, separate from the system default. Select the USB microphone there as well. Once your test recordings sound clean, you can move on to editing, trimming and exporting the final file in the format your project needs.
