The simplest way to record sound on Windows or Mac

The easiest way to record sound on your PC is to use the built-in recording tool that comes with your operating system. On Windows, that tool is the Voice Recorder app. On Mac, it's the Voice Memos app. Both are free, require no setup, and work when ready—you open the app, press the record button, and your microphone captures audio to a file you can play back or share.

If you want to record audio from your speakers instead of your microphone—for example, to capture music playing from a website or a video call—you'll need a different approach. Windows doesn't include a built-in speaker-recording tool, so you'll use free software like Audacity. Mac users can use QuickTime Player, which is already installed.

The method you choose depends on what you're recording: your voice through a microphone, audio from your speakers, or both at once. Each has a different set of steps.

Key Takeaways

  • Windows Voice Recorder and Mac Voice Memos are built-in apps that record your microphone with a single click and save files automatically.
  • To record audio from your speakers on Windows, read the free software Audacity and configure it to capture system audio.
  • Mac users can open QuickTime Player, select File > New Audio Recording, and choose their microphone or system audio from the dropdown menu.
  • Before you record, test your microphone or speaker volume by speaking or playing audio and watching the level meter move.
  • Audio files are saved as .m4a files on Mac and .m4a or .wav files on Windows, depending on the app you use.

Recording your microphone on Windows with Voice Recorder

Open the Voice Recorder app by typing "Voice Recorder" into the Windows search box at the bottom left of your screen and clicking the app when it appears. The app opens to a straightforward window with a large circular record button in the center and a microphone icon.

Before you record, speak into your microphone at normal volume and watch the blue waveform on the screen. If the waveform moves up and down as you speak, your microphone is working and the volume is set correctly. If nothing moves, check that your microphone is plugged in or connected, and that it's not muted. On a laptop, the microphone is usually built in; on a desktop, you may need to plug one in.

Click the large record button to start recording. The button changes to a pause button, and a timer appears showing how long you've been recording. Speak or play audio near your microphone. Click the pause button to stop recording. The app saves the file automatically with a timestamp as the name—for example, "Recording 2024-01-15 10-30 AM.m4a"—and stores it in your Recordings folder.

To find your recording later, open File Explorer, click "This PC" on the left, then double-click the "Recordings" folder. All your Voice Recorder files are there.

Recording your microphone on Mac with Voice Memos

Open Voice Memos by clicking the Launchpad icon (a grid of dots) in your dock, typing "Voice Memos," and clicking the app. The app shows a large red record button and a microphone icon. If you don't see Launchpad in your dock, open Finder, click Applications, and double-click Voice Memos.

Before you record, speak at normal volume and watch the meter on the left side of the screen. The meter should show green bars moving as you speak. If the meter doesn't move, your microphone may be muted or disconnected. Check System Settings > Sound > Input and make sure your microphone is selected and the input volume slider is not all the way down.

Click the red record button to start. The button changes to a pause button, and a timer shows how long you've been recording. Speak or play audio near your microphone. Click the pause button to stop. Voice Memos saves the file automatically and lists it by date and time. To find it later, open Voice Memos and scroll through the list, or use Spotlight search by pressing Command+Space and typing the date or time you recorded.

Recording audio from your speakers on Windows with Audacity

read Audacity from audacityteam.org by clicking the read button for Windows. Open the installer file and follow the on-screen steps to install it. Once installed, open Audacity from your Start menu.

Audacity opens to a blank project with a toolbar at the top. Before you record, you need to tell Audacity to capture audio from your speakers instead of your microphone. Look for the dropdown menu that says "Microphone" or shows a microphone icon. Click it and select "Stereo Mix" or "What U Hear" or "Speakers" (the exact name depends on your sound card). If you don't see any of these options, your sound card may not support speaker recording—see the FAQ section below for alternatives.

Once you've selected the correct input, click the red record button in the toolbar. Audacity starts recording. Open the website, video, or app that's playing the audio you want to record. The waveform appears in the project window as audio is captured. When you're done, click the pause button or press the spacebar. To save your recording, go to File > Export > Export as WAV (or MP3, depending on what format you prefer). Choose a location and filename, then click Save.

Recording audio from your speakers on Mac with QuickTime Player

Open QuickTime Player by clicking Launchpad, typing "QuickTime," and clicking the app. If you don't see Launchpad in your dock, open Finder, click Applications, and double-click QuickTime Player.

Click File in the menu bar at the top, then click "New Audio Recording." A small window appears with a red record button and a dropdown menu showing "Microphone." Click the dropdown and select "System Audio" to record what's playing from your speakers. If you don't see "System Audio" as an option, your Mac may not have that feature enabled—see the FAQ section for details.

Click the red record button. QuickTime starts recording all audio coming from your speakers. Open the website, video, or app that's playing the audio you want to record. When you're done, click the stop button (a black square). QuickTime shows a preview window. Click Save, choose a location and filename, and select the format (usually .m4a is fine). Click Save again to finish.

Common mistakes and how to avoid them

The most common mistake is forgetting to test your microphone or speaker volume before you start recording. If the level is too low, your recording will be quiet and hard to hear. If it's too high, the audio will sound distorted or "clipped." Always speak or play audio at the volume you plan to use, watch the meter or waveform, and adjust your microphone position or speaker volume until the meter shows a healthy level—usually somewhere in the middle of the green zone, not all the way at the top.

Another mistake is closing the app or shutting down your PC before the file is saved. Voice Recorder and Voice Memos save automatically, so this is less of a problem with those apps. But if you're using Audacity or QuickTime, always go through the File menu and explicitly save or export your recording before you close the app. If you close without saving, your recording is lost.

A third mistake is recording in a noisy room. Microphones pick up everything—keyboard clicks, fan noise, traffic outside, people talking in the background. If possible, record in a quiet room, close windows and doors, and ask people nearby to be quiet while you're recording. If you can't control the noise, you can use Audacity's Noise Reduction tool after you record (go to Effect > Noise Reduction), but it works better if the background noise is minimal to begin with.

Understanding audio file formats and where your recordings are stored

When you record sound on your PC, the app saves it as a file in a specific format. The most common formats are .m4a (a compressed format that takes up less space), .wav (an uncompressed format that takes up more space but sounds slightly higher quality), and .mp3 (a compressed format that's widely compatible). Voice Recorder saves as .m4a. Voice Memos saves as .m4a. Audacity and QuickTime let you choose the format when you save.

On Windows, Voice Recorder saves files in your Recordings folder, which is usually located at C:\Users\[Your Username]\Recordings. You can find it by opening File Explorer and clicking "This PC," then double-clicking the Recordings folder. On Mac, Voice Memos saves files in the Voice Memos app itself, but you can also find them in Finder by going to Locations > iCloud Drive > Voice Memos (if you use iCloud) or in your Music folder if you've exported them.

Audacity and QuickTime save files wherever you choose when you click Save. It's a good idea to create a dedicated folder for your recordings so you can find them easily later. For example, you might create a folder called "My Recordings" on your Desktop and save all your audio files there.

Frequently Asked Questions

Why can't I find "Stereo Mix" or "System Audio" in my recording settings?

Not all sound cards support recording from speakers. If the option doesn't appear in Audacity or QuickTime, your hardware may not have that feature. On Windows, you can try installing the latest audio drivers from your sound card manufacturer's website. On Mac, system audio recording is built in, but it may be disabled—check System Preferences > Sound > Input to confirm your microphone is selected. If you still can't record speakers, consider using a cable to connect your speaker output to a microphone input, or use a virtual audio cable tool like VB-Audio Virtual Cable (Windows) or Loopback (Mac).

How do I record both my microphone and my speakers at the same time?

In Audacity, you can create two separate tracks—one for microphone input and one for system audio—and record them together. Click Tracks > New > Stereo Track, then set one track to Microphone and one to Stereo Mix or System Audio. Click record and both will capture simultaneously. In Voice Recorder or Voice Memos, you can only record your microphone, not speakers. If you need both, Audacity is your best option.

Can I record a phone call or video meeting?

Yes, but the method depends on the app. For Zoom, Teams, or Google Meet, check the app's settings for a built-in recording option—most have one. For phone calls on your PC, use Audacity set to Stereo Mix or System Audio, or use a dedicated call recording app. Always check your local laws and the other person's consent before recording a conversation.

What should I do if my recording sounds muffled or too quiet?

If the recording is too quiet, your microphone was too far from your mouth or the input volume was too low. Re-record with the microphone closer to your mouth and the volume turned up. If it sounds muffled, the microphone may be blocked by dust or fabric, or you may be speaking too softly. Clean the microphone and speak clearly and directly into it. If the problem is with a speaker recording, make sure the speaker volume was turned up when you recorded.

Can I edit my recording after I save it?

Yes. Audacity is a free editor that can trim, cut, copy, paste, and explore effects to audio files. Open Audacity, go to File > Open, and select your recording. You can then edit it however you like and export it as a new file. Voice Recorder and Voice Memos have limited editing—you can trim the beginning or end, but not much else. For detailed editing, Audacity is the tool to use.
