Hello Everyone. Welcome to this tutorial on Installation of Audacity in Linux OS.
In this tutorial, we will learn about installation of Audacity
Lame library and FFmpeg library in the Linux Operating System.
To record this tutorial I am using Ubuntu LinuxOS version 14.04
Audacity version 2.1.2 And a working Internet connection
Audacity is a free and open source software.
It is used for multi-track audio recording and editing.
It is available for Mac OS X, Microsoft Windows, GNU/Linux and other operating systems.
Now let’s learn how to install Audacity in Linux OS.
Audacity comes pre-installed in Ubuntu Linux OS version 14.04 and above.
However, if it is not installed on your machine, follow any one of the below methods:
Go to the terminal and type sudo apt-get install audacity and press Enter.
Go to Ubuntu Software Center or Synaptic Package Manager, search for Audacity and install it.
To know how to install software in Linux, refer to the Linux spoken tutorials on this link
Audacity is already installed in my Linux system.
To open Audacity in Linux OS, click on Dash Home at the top left corner of the Desktop, And type Audacity and click on the icon.
This is how the Audacity interface looks like.
To cross-verify the installation, we will do a small demo recording.
Click on the button with the red dot.
Narrate a sentence - For eg: Welcome to Audacity.
Now, click on the yellow button to stop the recording
If you see waveforms below, then your Audacity installation is successful.
Let’s close this window now, without saving the recording.
This completes the demo for Linux OS.
Some important things to know about Audacity.
By default Audacity, will export the audio files in few formats only. Like dot ogg, dot mp3, etc.
A plugin called "Lame" is needed in Audacity, to export into mp3 format, in Linux OS.
It also uses the "FFmpeg" plugin to be able to read/import dot mp4 files in Linux OS.
Now let us learn about Lame installation in Linux OS.
Lame allows Audacity to export audio.
In Linux OS, Audacity has built-in Lame support for .mp3 export.
Hence a separate installation of Lame is not required.
So, you should be able to export to mp3 format in Audacity in Linux OS.
Let’s move on.
FFmpeg library allow Audacity to import audio from video files.
In Linux OS, Audacity has built-in FFmpeg Library support.
Hence a separate installation of the same, is not required.
This means that you should be able to import audio from video files using Audacity in Linux OS.
Let me show you a small demo of the same.
Note: I will import the audio from a video file named as Introduction-to-LibreOffice-Writer.mov in my Desktop.
Now, click on the Dash Home and type Audacity. And click on Audacity icon.
This will open an empty Audacity project on your screen.
Go to the Main menu, click on the File.
Now click on Import and then on Audio.
A dialog box will appear.
It will ask you to choose the location of the file.
I will choose Desktop and select my file Introduction-to-LibreOffice-Writer.mov.
Then click on Open.
It will import only the audio from this particular video.
You can see the audio track here.
This brings us to the end of the tutorial.
