Recording a simple file
Audacity makes recording simple. Plug in your headset to the computer so we can practice creating a voice recording. If using this program with students, it is recommended that students have a headset and microphone so that they won’t receive audio interference from others in the class. For most students, I recommend that you provide a scipt or have them read a passage. It is hard for many students to just begin speaking while they are being recorded.
Play it back
How did you sound? And what were those strange blue marks that appeared in
the program? Let’s look at figure to help us understand what is happening:
The default view (with the blue bars) is known as the Waveform view. While you
speak you can see the sound waves as they are processed by the computer and
converted to a digital audio file.
Saving and exporting projects
Now that you know how to create unique audio files, it is important to save the file in a format that you can open at a later point. Audacity files are saved as by default, with the file extension .aup. This means that Audacity is the only program that can open this file at a later time. If you plan on finishing a file on the same computer, use the Save or Save as…options located in the File menu.
However, if you have a finished project and want to play it on another computer or mp3 player, you will need to export the file to a different format. Audacity lets you export your file into different formats- waveform audio (.wav) or a MPEG audio layer 3 (.mp3) It is recommended that you export your project as a .wav file or .mp3 file. These two common formats are compatible with Windows Media Player or QuickTime. Depending on the length of your recording, you may need o convert it to an .mp3 file. A 60 second .mp3 file will be about 1 megabyte in size, while a .wav file the same length will be about 5 megabytes in size. Another benefit to .mp3 files is that you can encode them- which means you can add the artist’s name, genre and other data about the file.
To create an mp3: File menu – export and scroll down in type box to mp3
