How to Record Desktop Audio with Audacity on Linux

Meanwhile, recording computer audio with Audacity on Linux can be a bit more challenging than those first two operating systems. Linux does not have support for recording audio in the same way. To do so, you need some specific tools and configurations, e.g., PulseAudio, to route your system audio into Audacity for audio recording.

To understand it more, here’s how to record computer audio with Audacity on your Linux system:

Step 1.Install Audacity on Linux using your distribution’s package manager.

For Ubuntu/Debian: sudo apt install audacity. For Fedora: sudo dnf install audacity; and for Arch Linux: sudo pacman -S audacity.

Step 2.After that, install the PulseAudio Volume Control, depending also on your distributor.

For Ubuntu/Debian: sudo apt install pavucontrol. For Fedora: sudo dnf install pavucontrol, and for Arch Linux: sudo pacman -S pavucontrol.

Step 3.Now, launch the PulseAudio Volume Control, head to the "Recording" tab and ensure Audacity is running. There, choose "Monitor of Built-in Audio Analog Stereo" as your input device.

Linux Select An Input Sevice

Step 4.Run Audacity, click the "Device Toolbar" above, and set the "Audio Host" to "PulseAudio". Then, make sure the "Monitor of Built-in Audio Analog Stereo" is chosen in the "Recording Device", and the "Stereo" as your input channel. Click the "Record" button on this Linux screen recorder.

Fix Audacity Won't Record Computer Audio with Those Solutions

Sometimes, even after setting it up correctly to start the desktop audio recording, you may still face issues when recording computer audio. These issues can be no audio, laggy audio, low-quality sound, or others that are, luckily, solvable with the right adjustments.

Fix 1. Check Output Device.

When Audacity records nothing, ensure your system audio is outputting to the correct device. For example, if you use Soundflower on macOS, ensure the correct routing. Also, check on your system volume and the application’s audio output and make sure they are not muted.

Fix 2. Disable Audio Enhancements.

For fuzzy, distorted sound in Audacity, you can try disabling any enhancements in the Sound settings, then right-click on the icon and head to Playback Devices, then Properties. Otherwise, you can ensure that the sample rate matches your audio system.

Fix 3. Lower Latency.

If your audio is out of sync with the playback, lessen the buffer size under Latency, which you can see in Edit, then Preferences to Devices. Here, you can adjust with smaller sizes, but not too small since it may lead to glitches.

Conclusion

Recording computer audio with Audacity on all platforms offers a powerful solution for everyone looking to capture high-quality sound. Whether you want to record system sound and content or create podcasts, Audacity has a range of tools to enhance your recording experience. However, its setup is complex, so the AnyRec Screen Recorder emerges as the best alternative.
