2. One Tool at a Time:Enhancing Learning withAudacity Lawrence Walker University of Canterbury Christchurch New Zealand Webinar 12 January 2011
3. Content Sound and its place in our environment Quick run through on Audacity (screen demo) Using audio self model Working through an example using Audacity (Demonstration used 1.3 beta version)
4. Clean sound in quality out Microphones Speaking into a microphone (see notes in note section) Pop filters Settings (see http://audacity.sourceforge.net/manual-1.2/index.html
5. Setting up Audacity Preferences - Windows – edit menu Using copies of original sound files Use the default CD quality for recording
7. Simple recording Always start the recorder first Turn off the reorder last Easy to cut out extra material
8. What to record Children reading Children speaking Background noises ambient sounds
9. Demonstration Live demonstration showing editing of audio file to create an audio self model that can be played back to a student creating a Feedforward sound file. Sequencing and coping with multiple tracks Export as wav or mp3
10. Audio Self Model Prof Peter Dowrick – “Father of Video Self Modeling". Peter is a Professor of Disability Studies and Graduate Studies in Psychology at University of Hawaii, Professor Emeritus, University of Alaska; Honorary Professor of Psychology, University of Auckland. Feedforward – “A common example of feedforward is a video of a child reading fluently—a passage from a book that he or she actually would read haltingly, requiring quite a bit of help in some of the words. This type of example might be achieved by the child "echoing" one phrase at a time, and video editing used to put all the phrases together as fluent speech. This method works well for physical and motor skills as well.” From http://www.creating-futures.org/keystosuccess/feedforward/ Audio can be used in the same way to create an audio self model

Microphones- a good quaity microphone helps produce quality input. A headset microphone has the advantage of keeping a consistent distance from the mouth whereby ensuring quality voice input. Tabletop and handheld microphones are good for getting other sounds. About a hand width is a good distance from a microphone for recording – further away collects too much background sound.To reduce the popping effect of some sounds use a pop filter between the microphone and speaker. A circular frame about 4 inches in diameter with thin stocking mesh stretched over int worth well. If outside use a wind sock (thick foam over the microphone).
Good advice in the manual – its easier to down grade sound quality – start with good quality.
