00:01	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 LinuxOS 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.
