8 Free Ways to Record Computer Audio Perfectly [Full Guide]

You can record computer audio in many ways, including built-in audio capture programs, free open-source audio recording software, and professional sound recorders. Have you found out the best way to record audio in high quality? This article picks up 8 methods and elaborates on them in detail. Let's check for more information.

Quick Answer: How to Record Sound from Computer Efficiently

Ways to capture sound from PC may vary depending on your operating system, the audio type you want to grab, and your recording preferences. Here we offer 8 voice recorders for pc. Let's have a quick navigation, and you may choose the way that suits you most:

1️⃣Windows Sound Recorder. It is a Microsoft built-in audio recorder for Windows 11, 10, 8.1, 8, and 7 PCs (known as Voice Recorder in Windows 10). It can capture the microphone and speaker sound but cannot record system audio.

2️⃣Xbox Game Bar. Win 11 and 10 computers can use this native utility to ;record system audio and microphone at the same time. But it will capture the screen activity as well. Convert the MP4 video file to an MP3 audio file if needed.

3️⃣Stereo Mix. If the sound card of your Windows laptop or desktop supports Stereo Mix (also known as What-U-Hear), enable and use it as the recording device. But it is just a loopback device, not a voice recorder. You can use free open-source audio recording software (such as Audacity and OBS) and select Stereo Mix as the speaker output device to capture audio from PCs for higher quality.

4️⃣Audacity and OBS. They support Windows, Mac, and Linux operating systems. They can capture high-quality internal and external voice from high-quality computers for free. However, it can be a little complicated for novices and requires a longer learning curve.

5️⃣QuickTime Player with extra add-on. Mac users can use this built-in recorder to record MP3 audio files on MacBook. But it only captures the external audio. You need to configure another plugin, such as Soundflower and Black Hole, to record internal audio on Mac.

6️⃣Third-party audio recorders. They are easier to operate and let you capture sound from a pc without losing quality and background noise. You can record computer audio for free and save the audio file at a limited length.

7️⃣Web-based online screen recorder. This is a good choice if you want to record music and voice from the computer without installing apps. You can capture the desktop speaker, microphone, and system sound with a browser directly on Windows, Mac, and Linux. But this often offers limited recording abilities only.
