Open the app in your browser to record sounds from the computer.

Step 2. Set Up Audio Recording and Record System Sound

To record your PC’s audio, enable the Sound icon. If you need to capture sound from your speakers or microphone, activate the Microphone icon.

Press the Start Recording button to grab the audio playing. Allow access to your microphone and webcam. Your privacy will be quite secure!

Choose the tab to start recording.

The second best way to grab system sounds is to use a desktop program. We recommend you try Audacity. It’s a free program that grabs internal audio on macOS, GNU/Linux, Windows (including Windows 7) and other operating systems.

Advantages of the program:

  • It offers advanced audio editing tools and many audio effects.
  • It has a wide range of output formats, including MP3.
  • The program is absolutely free of charge.

Disadvantages of Audacity:

  • Challenging interface with a daunting number of settings
  • No screen or webcam recording
  • Sometimes audio effects can spoil the sound quality

Now we’ll show you how to record desktop audio with Audacity.

Step 1. Download the App

Go to the Audacity website and download the program onto your computer.

Step 2. Choose the Settings and Record the Audio

Before you start recording, you need to choose the appropriate settings. The main parameters are audio host and loopback device.

If you’re recording sounds on Windows, you need to choose Windows WASAPI audio host. In the loopback device menu choose Stereo Mix to grab internal audio.

When you’re done with the recording parameters, hit the Record button.

Step 3. Save the Recording

If you want to add effects, you can do this right after recording. But we recommend you save the file first.

Open the File tab and select the Save Project option. Now export the file to your hard disk and continue audio editing. Even if something goes wrong, you’ll have an audio copy on your computer.

How to Record Audio on PC with the Built-In Windows Tool

Best for: simple audio recording on Windows

The last option we’d like to suggest is the built-in Windows tool – Windows Voice Recorder. It’s the easiest way for Windows users to grab external sounds. You just need to check the computer microphone accessibility and capture your voice.

But the tool only works for microphone recording. It doesn't capture internal audio playing on your computer.

Advantages of the tool:

  • Simplicity and fast accessibility
  • No installation
  • Can be used offline

Disadvantages of Windows Voice Recorder:

  • No internal audio recording
  • No audio editing tools

Here are step-by-step instructions on how to use this built-in Windows app.

Step 1. Check Your Microphone

First of all, check that your microphone is turned on. Open the system settings and go to the Input tab. Here you need to choose your microphone from the drop-down menu and set the volume.

Step 2. Open Windows Voice Recorder

Launch the Start menu and search for Windows Voice Recorder using the search bar. Click on the program icon to open the app.

Step 3. Make Your Audio Recording

You’ll see the microphone icon on your screen. Hit it and start speaking. Be close to your microphone to get clear sound.

When you’re done, stop recording. The file will be automatically saved to the Sound Recordings folder.
