Windows 11 includes a built-in Voice Recorder (also called Sound Recorder) app that allows you to record audio easily. However, it can only capture sound from a microphone and cannot record system audio directly.
If you want to record audio playing on your computer—such as music, streaming audio, browser read-aloud voices, or online radio—you will need a third-party tool.
In this guide, you will learn how to record internal audio on Windows 11 using Audacity with the WASAPI loopback feature.
Why You Can’t Record System Audio with Voice Recorder
The built-in recorder in Windows 11 is limited to microphone input and does not support recording:
- System sound
- Streaming audio
- Browser audio (such as Edge read-aloud)
- App audio output
To capture these types of audio, you need software that supports loopback recording.
Best Free Tool: Audacity
Audacity is a free, open-source, and powerful audio recorder and editor available for Windows, macOS, and Linux. It supports multi-track recording and allows you to capture internal audio using Windows WASAPI loopback.

How to Record System Audio on Windows 11
Follow these steps to record internal audio using Audacity:
Step 1: Enable Device Toolbar
Open Audacity, click View in the top menu, then select Toolbars and enable Device Toolbar.
