Podcasting Software Audacity and LAME


 

Minutes to get familiar with


40-50 minutes (5 mins to download over fast network). This is all for Audacity.

 

Ages suitable for

Any but most suitable for Y5-Y9

 

Key Features

  • Microphone – you need one of these!
  • Red button – RECORD!
  • Import Audio – ALLOWS YOU TO ADD SOUND TO YOUR PODCAST.
  • Export as mp3 – sends you to LAME for conversion to mp3 – so you can podcast/email
  • Change volume – on each track so you can turn down music and turn up voice.
  • Help Menu – this has a simple guide to using Audacity and explains all the buttons.

 

Health Warnings

  • There are a lot of technical elements which are best left alone if you aren’t familiar with recording software.
  • This doesn’t create video podcasts but see PICASA page for how to use mp3 files to create videos!
  • Unless you convert through LAME then anyone you email the file to must have Audacity.

 

How to introduce

  • Download Audacity to your class computer and connect a microphone.
  • Open Audacity and explain that the class is going to complete a podcast.
  • Show the class the record button (red one) and record some sound – can be just class singing happy birthday.
  • Once recorded show the class how to increase or decrease the volume on that track.
  • Show them how to import an mp3 file to play music or other sounds over the happy birthday track.
  • Finally show the class how to export the podcast to an mp3 file for emailing or putting onto i-tunes.

 

Quick Activities (skills)

1)      Scripting and Recording :  Working in pairs, ask children to create a script they can use to create a podcast – this could be jokes, revision questions, an interview. Ask them to record the script using both voices.

2)      Editing a Sound File: Using their sound file ask children to cut some sound (using the cursor tool and shift to select, then delete), import an mp3 file (make sure there are some on the computer) and change the volume of a track.

Longer Activities (capability)
