Want to hear your sound in microphone? Here’s a stupid simple tool to the job in Linux.

It’s Whisper, a new free and open-source GTK4 application, allowing listen to microphone through your speaker. Which, is useful for testing your microphone or for listening to your voice.

As the screenshot shows, the app is quite easy to use. Just select the microphone and speaker from the list, and click ‘Connect’. Then, you can say something or make some noise through microphone to see the magic.

As a GTK4 application, it follow system color scheme by switching between light and dark automatically. However, it needs both PulseAudio and Pipewire to make things work, which is default in Pop! OS 22.04, Ubuntu 22.10, Ubuntu 23.04, Fedora 35/36/37, etc.

How to Install Whisper in your Linux

As mentioned above, this application requires Pipewire audio server. For current Ubuntu 22.04 LTS, it’s NOT the default, though you can enable it by following this tutorial (NOT recommend for beginners).

Whisper is available to install as universal Flatpak package. You can install it by following the steps below one by one:

1. First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to install Flatpak daemon:

sudo apt install flatpak

Other Linux can follow this setup guide to enable Flatpak support.

2. Then, run command to install Whisper as Flatpak package:

flatpak install https://dl.flathub.org/repo/appstream/it.mijorus.whisper.flatpakref

3. After installation, search for and launch it from start menu (Show Applications) like normal app and enjoy!

How to Remove Whisper

To remove the software package, also open a terminal window and run command:

flatpak uninstall --delete-data it.mijorus.whisper

Also run flatpak uninstall --unused to remove useless runtime libraries.

Ubuntu by default play a short alert sound when you plug in/out USB drive, power supply, or hit tab function key in terminal.

This is useful for indicating certain type of system messages and events, but it’s easy to mute these type of sounds in case you don’t like them. And, here’s the quick tutorial show you how.

Single command to disable event sound

There’s a dconf database option to toggle on/off this feature for GNOME and Cinnamon desktop.

Simply, press Ctrl+Alt+T key combination on keyboard to open terminal. When it opens, run command:

gsettings set org.gnome.desktop.sound event-sounds false

Not only for Ubuntu, this command should also work for Fedora workstation, Debian, Arch and other Linux with GNOME desktop.

For Linux Mint cinnamon desktop, use the command below instead:

gsettings set org.cinnamon.desktop.sound event-sounds false

Disable event sound via Dconf Editor (graphical way)

In case for those who hate Linux commands, there’s an advanced configuration tool Dconf Editor, that provides a graphical interface to do the job.

1. Firstly, search for and install Dconf Editor from Ubuntu Software (or your system package manager).

2. Then launch Dconf Editor, and navigate to org/gnome/desktop/sounds. Finally, turn off the option for ‘event-sounds’.

Similarly, navigate to org/cinnamon/desktop/sounds or org/mate/desktop/sounds and set the key depends on your desktop environment.

That’s all. Enjoy!

Want to display audio/music visualizer on the desktop? This extension can do the job for Ubuntu 22.10, Fedora 37, Arch/Manjaro Linux with GNOME.

It’s “Sound Visualizer” extension for Gnome Shell based on Gstreamer specially for Wayland. And, it’s working good in my case in Ubuntu 22.04, though it’s said for Gnome v43.

Besides for music playback, it works when any sound play from your computer. And, it has a right-click menu to switch between input/output audio sources. Meaning, it supports sounds input from microphone.

How to Install this “Sound Visualizer” desktop widget

1. (For Ubuntu 22.04 only) As mentioned, the extension supports GNOME v43 at the moment of writing. If you want to try it out in 22.04, first disable extension version validation.

To do so, press Ctrl+Alt+T on keyboard. When it opens, run command:

gsettings set org.gnome.shell disable-extension-version-validation true

2. Next, open Ubuntu Software. Search for and install ‘Extension Manager‘ tool for installing and managing Gnome Shell extensions. Or, run command in terminal in case the Software App does not work.

sudo apt install gnome-shell-extension-manager

Install Extension Manager in Ubuntu 22.04+

3. Finally, launch ‘Extension Manager‘, and navigate to ‘Browse‘ tab. Search for and install the ‘Sound Visualizer‘ extension. (For Ubuntu 22.04, just click on Unsupported button)

For Fedora 37, Arch and Manjaro Linux with GNOME, visit this page in web browser and use the ON/OFF switch to install it.

4. After installation, try playing some sounds and see your desktop for the result. To move the widget, you have to temporarily disable “Desktop Icons NG (DING)” under ‘Installed’ tab in Extension Manager.

You can also adjust the visualizer size by opening the extension preferences either via widget’s context menu or by clicking the gear button for that extension in Extension Manager.


Audacity audio editor got a new major update few days ago, features real-time effects and VST3 support.

In the new 3.2.0 release, there’s a new “Effects” button in the tracks menu, allowing to place realtime effects. However, it does not yet ship with any effect so far. User has to get effects via plugins, though only Audio Units (macOS only), VST3, LV2, and LADSPA formats are supported at the moment.

The release also merged the mixer bar with the meter bars. The device tool-bar has been replaced with a new Audio Setup button, though it can be re-enabled via “View -> Toolbars” menu.

As the screenshot above shows you, there also introduced a new “Share Audio” button, allowing to upload audio into audio.com either with login account or anonymously, then share the link with your friend.

Other changes in Audacity 3.2.0 include:

  • Apple Silicon (arm64) is now supported on macOS. Though, need arm64 versions of FFMPEG and plugins.
  • Add support for Wavpack
  • Possible to compile without JACK present in Linux.
  • Use XDG directories on Linux. Need to delete .audacity-data and .audacity folders in user home if exist.
  • Use mpg123 as mp3 importer instead of mad.
  • Update license to GNU General Public License V3, though most code files remain GPLv2 or later.
  • Update icons, remove Zoom tool and various bug-fixes.

How to Install Audacity 3.2.0 in Ubuntu Linux

There seems no native .deb package for the latest Audacity. User can however get the application via the universal AppImage, Snap, or Flatpak that works in most Linux.

Option 1: AppImage

For the non-install AppImage, go to the github releases page and grab the package under “Assets” section:

Then, right-click on the package and open “Properties” dialog. Add executable permission under ‘Permissions’ tab and finally click run the package to launch Audacity.

Audacity AppImage

Option 2: Flatpak

User can also install Audacity via universal Flatpak package that runs in sandbox.

First, press Ctrl+Alt+T on keyboard to open terminal in Ubuntu, then run command to make sure the daemon package is installed:

sudo apt install flatpak

Then install the audio editor as Flatpak by running command:

flatpak install https://dl.flathub.org/repo/appstream/org.audacityteam.Audacity.flatpakref

Like normal applications, search for and launch it from system start menu (‘Activities’ overview) after installation.

Option 3: Snap

Audacity is also available as Snap package that runs in sandbox. I put this method as last choice because it does not yet update to v3.2.0 at the moment of writing.

However, it’s quite easy to install for Ubuntu users. Simply open the Software App, search for and click install it:

Uninstall Audacity

Depends how you install the software package, uninstall the editor via:

  • For AppImage, just remove the package file.
  • For the Flatpak package, open terminal and run command:
    flatpak uninstall org.audacityteam.Audacity
  • And remove the snap package by either using Ubuntu Software or running command in terminal:
    sudo snap remove audacity
