===Working with the application===
====Obtaining Audio from different sources====
Audio file can be obtained from many different sources such as audio recorders in phone, camera or laptops. Audio recording in laptops can be done using Audacity which is explained in [[Learn Audacity#Step3|Step 3]] below. Similarly audio can be recorded in other recording devices and transferred to a laptop to edit them using Audacity. Importing audio files from different sources to the laptop is explained in [[Learn_Ubuntu#Step8|Step 8 of Learn Ubuntu page]].
====Recording with Audacity====

[[File:Audacity 3 Start Record.png|left|frame|Step 3]]
To start recording, click the '''red record''' button in the Toolbar as shown in the left image. Begin talking or playing any audio and continue for as long as you want. When you feel you've recorded enough, click the '''yellow stop''' button. Until you stop the recording, other functions on the Menu and Toolbar will be disabled. You can record an audio playing on your computer itself, or playing in an another external audio device

==== Importing audio and multiple tracks ====

File:Audacity_4_Add_New_track.png|Audio track and adding new track
File:Audacity 5 Multipal Track.png| Multiple tracks
</gallery>
To import audio, click File -> Import -> Audio from the menu as shown in the first image above. Choose the music file from your computer, and then click on Open. Once you import an audio clip it will appear in Audacity as an audio track as you can see in second image. If you want to add multiple tracks, you can do so by clicking on Tracks -> Add new -> Audio track from the Menu as shown in the same second image. With use of multiple tracks, you can record and at the same time import several audio tracks to work in Audacity as shown in third image above.
==== Basic audio editing ====

File:Audacity 6 Delete middle Song.png|Selection of Audio
File:Cut selected audio clip for moving to other place - audacity.png|Cutting selected audio
File:Paste selected audio clip to other place - audacity.png| Pasting selected audio
</gallery>Similar to how we do cut (or copy) paste a selection of text in a text document, we can cut (copy) and paste a selection of audio in an audio file in Audacity. To delete a part of the track, we can select the area of track we wish to delete as shown in first image above and then press '''delete''' key on keyboard to delete. To move a part of audio to another place in same track or to another track, we need to select it first as we did before and then click on cut icon on the toolbar as shown in second image. Then the same audio can be pasted by clicking on paste icon on the toolbar as shown in third image above. The usual keyboard shortcuts for cut(<code>'''Ctrl+X'''</code>), copy(<code>'''Ctrl+C'''</code>) and paste(<code>'''Ctrl+V'''</code>) will also work on Audacity. Once you are done with editing, the final audio can be exported to any audio format from the Menu by clicking on File->Export and then Save.
==== Saving and exporting to different formats ====
# All the edits including files can be saved in '''''uncompressed''''', '''''lossless''''' quality using the '''''AU''''' format. An '''''AUP''''' project file is created, along with a folder with the same name as the AUP file that contains the project's audio data. For example, if you save a project as <code>chanson.aup</code>, a folder called <code>chanson_data</code> will contain the audio data. We can save the '''''AUP''''' project file with keyboard <code>'''Ctrl+S'''</code> shortcut or through File->Save from the Menu.
# Exporting to different audio formats can be done with <code>'''Ctrl+Shift+E'''</code> keyboard shortcut or by clicking on File -> Export through Menu. List of all available export formats supported by Audacity can be found [http://manual.audacityteam.org/man/export_formats_supported_by_audacity.html here].
==== Advanced features ====
Audacity is a full-fledge audio editor which has many advanced features. [http://manual.audacityteam.org/man/tutorials.html This page] lists tutorials that provide step-by-step instructions for performing all the interesting things with audio in Audacity.
=== Ideas for resource creation ===
This tool can be used to create own voice recordings, modify existing audio as per academic requirements and to mix multiple audio files together to create educational resources.
