Audacity 2.1.3 Released! Install it in Ubuntu 16.04 & Higher

Last updated: March 18, 2017

After more than one year of development, the Audacity audio editor has reached the 2.1.3 release. Here’s how to install it in Ubuntu 16.04, Ubuntu 16.10, and their derivatives.

Thanks to an upgrade of the PortAudio library, Audacity 2.1.3 now properly supports Windows 10. It also features:

Added support for Magic Mouse/Trackpad on mac OS.
New Distortion effect, Rhythm Track (was called Click Track) and Sample Data Import. Also effects are no longer grayed-out when in pause.
New scrub ruler and ‘pinned’ option so the waveform moves and the recording/playing head stays still.
New features in Timer Record.
On Mac, audacity.app is now added to /Applications/ directly rather than adding a folder there.
Over 60 bugs fixed, including five longstanding bugs.

How to Install Audacity 2.1.3 in Ubuntu via PPA:

The Audacity Team does not offer official builds of DEB packages. Besides building from source, you can install Audacity 2.1.3 from my PPA (unofficial). Ubuntu 14.04 is excluded due to requirement of GCC >= 4.9.

1. Open terminal by pressing Ctrl+Alt+T or searching for “Terminal” from Unity Dash. When it opens, run command to add the PPA:

sudo add-apt-repository ppa:ubuntuhandbook1/audacity

Type in your password (no visual feedback due to security reason) when it asks and hit Enter.

2. After that, upgrade Audacity via the Software Updater (Update Manager) utility:

Or you can run the commands below one by one to install or upgrade the audio editor:

sudo apt update

sudo apt install audacity

Uninstall:

For any reason, you can easily remove the PPA and downgrade Audacity to the stock version in Ubuntu via the ppa-purge tool:

sudo apt install ppa-purge && sudo ppa-purge ppa:ubuntuhandbook1/audacity

Stop Onscreen Keyboard ‘Onboard’ Auto-Starting in Ubuntu 16.04

Last updated: March 17, 2017

After first time launching the onscreen keyboard in the login screen, the ‘onboard’ onscreen keyboard automatically starts up every time when I login, or backup from suspend.

The software does not offer an option to enable / disable the auto startup feature. So here’s how to stop Onboard onscreen keyboard from auto-launching using the Startup Applications utility.

1. Open terminal by pressing Ctrl+Alt+T or searching for “Terminal” in Unity Dash. When it launches, run command:

sudo sed -i "s/NoDisplay=true/NoDisplay=false/g" /etc/xdg/autostart/*.desktop

Type in your password (no visual feedback due to security reason) when it asks. The command will show hidden startup applications in the Startup Applications utility including Onboard.

2. Launch Startup Applications utility, find out “Onboard” and un-check or remove it:

3. (Optional) You may re-hide these hidden startup applications by running the command below in terminal:

sudo sed -i 's/NoDisplay=false/NoDisplay=true/g' /etc/xdg/autostart/*.desktop

That’s it. Enjoy!
