Audacity, a freely available audio editing program, is one of my essential, go-to teacher tools – so much so that it is pinned to my taskbar and enjoys almost daily use.
There are many things you can do with Audacity that is useful for teaching. For example, you can slow down audio or speed it up; you can cut, shorten, and manipulate audio (such as TED Talks!); you can record your own audio samples; you can record students; students can make their own podcasts; you can analyze waveforms and spectrograms in a pronunciation class; and you can make really cool listening quizzes (an idea for a future blogpost of mine). Really, the list is endless.
The point of this blog post is to show you how I use Audacity to quickly cut up audio for vocabulary, transcription, and paraphrasing practice.
The first thing you need to do is download Audacity. In addition, you’ll need to download and install the LAME MP3 codec in order to save .mp3 files (Windows users click here, Mac users click here). Once installed, you’re ready to go.
The quickest way to cut up audio is the use of labels. This allows you to select a section of audio, label it with a name, and then later export all the sections as separate files with a few clicks. I’ll try to give step-by-step instructions with pictures.
- Open the program and load the track you want.
- Listen to the track until you find a clip you want. Then highlight the clip and press CTRL + B. Give the label a name. In my example, it is “v – addictive”. This means the clip contains a short phrase with the vocabulary word “addictive” in it.
- Continue labeling. If there are two sections together or nearby, you may have to zoom in to be more accurate.
- When you are finished, Audacity should look like this (zoomed out).
- Next, go to File -> Export Multiple. This will allow you to export each clip/label you made separately.
- You’ll see a dialog box. Make sure to select “MP3 Files” under format, select a location, and choose whatever other options you’d like. The setup below is what I typically use. It will produce MP3 files in the folder I specified that are named only by the label I used.
- Press “Export” and you will see the box below. This will appear for EVERY label you created, so all you have to do is click “OK” multiple times in succession – unless you wish to read the information for each file.
- When the process is finished, you’ll see a list of your files.
- Open the folder, and you’ll see something like this:
- Now, the fun part…what to do with all those files? Here is an example – a game I play called “Popcorn Vocab“. I simply drag the files I want into a PPT and then arrange them to be easy to use. In class, I’d set up the popcorn game by telling students to list for the vocab (which we have already studied) and JUMP in the air and shout the word when they hear it. The first to jump/shout gets a point. OR, if two students jump/shout at the same time, they are both out. This last change is adapted from the Korean nun-chi game. Check the blog post I linked to to get a better explanation.
