|  Hello Everyone. Welcome to this tutorial on '''Installation of Audacity in Linux OS.''' 

|- 
| 00:09
|  In this tutorial, we will learn about installation of 

'''Audacity''' 

|- 
| 00:16
|  '''Lame library'''  and '''FFmpeg library''' in the '''Linux Operating System.''' 

|- 
| 00:23
|  To record this tutorial I am using 

'''Ubuntu Linux'''OS version 14.04 

|- 
| 00:30
|  '''Audacity '''version 2.1.2 

And a working '''Internet '''connection 

|- 
|00:38
|  '''Audacity '''is a free and open source software. 

|- 
| 00:42
| It is used for multi-track audio recording and editing. 

|- 
| 00:47
| It is available for '''Mac OS X, Microsoft Windows, GNU/Linux''' and other '''operating systems'''. 

|- 
| 00:57
|  Now let’s learn how to install '''Audacity''' in '''Linux OS'''. 

|- 
| 01:02
|  Audacity comes pre-installed in '''Ubuntu Linux OS version 14.04''' and above. 

|- 
| 01:09
|  However, if it is not installed on your machine, follow any one of the below methods: 

|- 
| 01:16
|  Go to the '''terminal''' and type '''sudo apt-get install audacity ''' 

and press '''Enter.''' 

|- 
| 01:28
|  Go to '''Ubuntu Software Center''' or '''Synaptic Package Manager''', search for '''Audacity''' and install it. 

|- 
| 01:37
| To know how to install software in '''Linux,''' refer to the '''Linux '''spoken tutorials on this link 

|- 
| 01:45
|  '''Audacity''' is already installed in my '''Linux '''system. 

|- 
| 01:49
|  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. 

|- 
| 02:02
|  This is how the '''Audacity''' interface looks like. 

|- 
| 02:06
|  To cross-verify the installation, we will do a small demo recording. 

|- 
| 02:12
|  Click on the button with the red dot. 

|- 
| 02:15
|  Narrate a sentence - For eg: '''Welcome to Audacity.''' 

|- 
| 02:21
|  Now, click on the yellow button to stop the recording 

|- 
| 02:25
|  If you see waveforms below, then your '''Audacity''' installation is successful. 
 
|- 
|02:31
|  Let’s close this window now, without saving the recording. 

|- 
| 02:36
|  This completes the demo for '''Linux OS.''' 

|- 
| 02:40
| Some important things to know about '''Audacity'''. 

|- 
| 02:44
|  By default '''Audacity,''' will export the audio files in few formats only. Like '''dot ogg, dot mp3''', etc. 

|- 
| 02:57
| A plugin called "'''Lame'''" is needed in '''Audacity, '''to export into '''mp3''' format, in '''Linux OS.''' 

|- 
| 03:06
| It also uses the '''"FFmpeg'''" plugin to be able to read/import '''dot mp4''' files in '''Linux OS.''' 

|- 
| 03:15
|  Now let us learn about '''Lame '''installation in '''Linux OS'''. 

|- 
| 03:20
|  '''Lame '''allows '''Audacity''' to export audio. 

|- 
| 03:24
| In Linux OS, Audacity has built-in Lame support for .mp3 export. 

|- 
| 03:32
| Hence a separate installation of Lame is not required. 

|- 
| 03:37
|  So, you should be able to export to '''mp3''' format in '''Audacity '''in '''Linux OS'''. 

|- 
| 03:45
|  Let’s move on. 

|- 
| 03:47
|  '''FFmpeg library''' allow '''Audacity''' to import audio from video files. 

|- 
| 03:54
| In '''Linux OS, Audacity''' has built-in '''FFmpeg Library''' support. 

|- 
| 04:00
| Hence a separate installation of the same, is not required. 

|- 
| 04:05
|  This means that you should be able to import audio from video files using '''Audacity''' in '''Linux OS'''. 

|- 
| 04:14
| Let me show you a small demo of the same. 

|- 
| 04:18
| Note: I will import the audio from a video file named as '''Introduction-to-LibreOffice-Writer'''.'''mov''' in my '''Desktop'''. 

|- 
| 04:29
| Now, click on the '''Dash Home''' and type '''Audacity'''. 

And click on '''Audacity '''icon. 

|- 
| 04:38
| This will open an empty '''Audacity''' project on your screen. 

|- 
| 04:43
| Go to the '''Main menu''', click on the '''File.''' 

|- 
| 04:47
| Now click on '''Import''' and then on '''Audio.''' 

|- 
| 04:53
| A '''dialog box''' will appear. 

|- 
| 04:56
| It will ask you to choose the location of the file. 

|- 
| 05:00
| I will choose '''Desktop '''and select my file '''Introduction-to-LibreOffice-Writer'''.'''mov'''. 

|- 
| 05:09
| Then click on '''Open'''. 

|- 
| 05:12
| It will import only the audio from this particular video. 

|- 
| 05:17
| You can see the audio track here. 

|- 
| 05:21
|  This brings us to the end of the tutorial.
