Record/edit/format audio

What you need:

To record (or capture) audio you need a microphone attached to hardware that can save the microphone input.  Voice recorders, iPods with recording accessories, laptops, some mobile phones can all be used to record audio.  To edit and format audio you need an audio editing tool such as Audacity.

How you do it:

Most audio recorders have buttons for record, pause, stop and save.  If you are recording from a mobile device such as a voice recorder or mobile phone, you may also need to transfer your audio file to a computer if you want to edit or format it.

Audio editing tools such as Audacity allow you to playback the audio in a file, select portions of the audio and copy, paste, edit or delete your selection (in much the same way you can copy, paste, edit or delete text you select in a text editing program such as Microsoft Word).  When you're done editing, you'll need to save your audio is a format appropriate for where you plan to use it.

Tips and suggestions:

Save as .mp3: MP3 is an open standard audio format that is widely supported.  Most audio editing tools allow you to save in this format and nearly all media devices can handle this format.

Add metadata: Most audio editing tools will allow you to add more information about your audio file that can be used by media applications such as a iTunes to organize your audio.  The standard for this information (ID3) was originally created for music files but conventions are emerging for using these fields for storing information about podcasts, audiobooks, lectures as so on.  Here are some tips:

  • Name: title of audio that best represents what is it
  • Artist: instructor, speaker, performer, author...
  • Album: course, department, conference...
  • Genre: subject, department, organization...
  • Comments: additional information about audio

Case Studies

Faculty teaching languages often record audio of the language they are teaching.  These recordings range from those containing a single word to recordings of conversations, performances or the reading of literary works.  For case studies of recording audio for curricular use, see:
