Audacity - Creating Audio Files

Recording and editing audio files

Recording audio files to complement written materials is a simple way to add multimedia to your unit. 

A free tool (available to download online) which can be used to record audio files is Audacity. It can be downloaded free from and is available in versions for Windows, Mac and Linux. Audacity is generally considered to be the simplest free application which enables audio to be recorded, edited and downloaded.

While audio recordings do not need to be made in Audacity, they should ideally be created in or converted to mp3 format for uploading to Moodle. A range of alternative tools and apps are available for recording audio files (for example Garage Band (Apple), Windows sound recorder (PC), Voice Record Pro (iOS devices), Smart MP3 Recorder (Android)). While some applications will be easy to use, they may have limited editing functionality and they may not automatically save in .mp3 format. You could also record using a hand held or stand alone voice recorder. A range of converters which allow you to convert various audio file types to .mp3 are also available on the web, for example:

Instructions are presented below for using Audacity.

Getting Audacity

To download Audacity, go to the following website:


Choose the download that suits your computer (eg. if you have a PC using Windows, you choose the Windows icon). Download the program and install it as outlined in the installation instructions.

In addition to Audacity, you will need to download what is known as an “LAMEmp3 encoder”. LAME is a little computer program that converts your Audacity-recordings (these will have the extension .aup) into .mp3 format. To do this go to the Lame download page. Instructions for downloading and installing the LAME MP3 encoder are available from 

The following videos give a demonstration of installation for both Windows and Mac (these relate to a previous version of Audacity, but the process will be similar aside from links, which are included above).

Tutorial for Mac

Atomic Learning also has a series of Audacity tutorial videos which UNE staff and students can access (login with your UNE username and password).


Once you have downloaded Audacity and LAMEmp3, you are ready to start! A headset with a microphone is recommended for making recordings.

Open Audacity:

Recording in audacity

    • to record, click on the big red circle button.
    • to stop, press the pause button (two blue stripes). When you recommence recording, press pause again. This means you continue recording on the same track.
    • when you are finished, press the stop button (yellow square). This ends the recording. If you want to add something after you have pressed stop, you will need to press Record again. A new track will appear and your addition will be on this track. You can copy and paste the new track onto the end of the first one. You might want to practise this.
    • to listen to your recording, press play (green triangle).
    • once you are satisfied with your recording, export the file (File > Export).
    • then choose file type MP3 from the 'Save as type' menu (see below).

save mp3

Note: It is a good idea to save the project file in Audacity as well as exporting to .mp3 in case you want to access it later. To do this, click File> Save Project or File> Save Project as...
