Recording sound using Audacity

In-page imageWhy use Audacity?

Audacity is free, open source software for recording and editing sounds.  By creating your own sound recordings you reduce the time searching for suitable, copyright-free sound clips to download from the Internet. It is an easy tool to use to produce narrations to accompany a learning resource or to create realistic language tasks.  The software is user-friendly and has effective editing functions such as:

  • Record live audio.
  • Convert tapes and records into digital recordings or CDs.
  • Edit Ogg Vorbis, MP3, and WAV sound files.
  • Cut, copy, splice, and mix sounds together.
  • Change the speed or pitch of a recording.

The editing functions within Audacity allow you to remove any mistakes from a recording, to enhance a recording and remove ‘white noise’ and you can also  'mix' different sounds together, add music to your recording, or add sound effects and different background atmospheres.

The selection tool

In-page imageThis is used to find specific points in the waveform and to highlight relevant sections so that you can zoom in, cut or copy them.  When this tool is selected and you click on the waveform, you will see a vertical cursor within the wave like this:

The time shift tool

This is used to move the waveform around inside its track. Click on the tool, click on the waveform and with the left mouse button held down, slide the wave along the track into the position you want it.

The magnifier tool

With this, you can zoom in or out of the waveform. To zoom in, select the magnifier and then click on the left mouse button. To zoom out, click on the right mouse button. Copying, cutting and pasting sections of the waveform is just like cutting and pasting text in a word document.

Cutting

In-page imageTo remove a clip of audio that you don't want, highlight the relevant section with the selection tool. The highlighted section will appear darker: Click on 'edit' and 'cut' or press the backspace key to delete the section.

Cutting and pasting

If you want to move one part of the waveform and put it somewhere else, highlight the relevant section, click on 'edit' and 'cut'. Place the selection cursor at the new position for the material, click on 'edit' and 'paste'

Zooming in on the waveform

Sometimes you may need to zoom in on the waveform to find the exact edit point. When you zoom in, you are effectively stretching the wave out. Highlight the part of the wave you want to see in more detail. Click on the 'fit selection in window' icon.  This will stretch your highlighted piece across the whole window. If you need to zoom in any further, click on the magnifier tool.  When you want to see the whole waveform again, click on the 'fit project in window' icon.
