The class have been working with audacity to create a pod cast. Today we exported our completed work as an MP3. This lossy compression standard is used by many people to share audio files.
BGE – Postcast

BGE – Media Type (Audio)
In class today we used Audacity to explore how sound is stored inside a computer.
The sound wave energy is converted into electricity by the microphone, which is in turn converted to binary by the sound card.
We used Audacity to capture our voices then apply digital effects to them to change the sound.
You can use specialised websites and software such as http://sfbgames.com/chiptone , to create purely digital noises. These can then be saved and used inside other programs such as games.
Website split
We have decided to move the Broad General Education (BGE) computing course to its own web site. This will allow this site to focus more on the senior phase and it’s assessment.
Higher – Responsive web design in PagePlus X8
Not everyone uses a desktop computer to view web pages. A significant proportion of the population now uses mobile devices to view websites. This means that designers have to use a website design that can respond to these devices by changing page size, position of elements, etc. Normally this would be done with CSS scripting however the process is slightly different in WebPlus.
WebPlus
Classes have now started using WebPlus for website development.
BGE – Top Trumps Database
Today we analysed a pack of top trumps Beano cards. Pupils were asked to identify field names and types. This was then put into a table before we created the database in Access.
How do you think you would turn this database into a game?
BGE – Databases
This week we are going to create a database using Top Trumps as the information source.

3G JPEG Investigation
Today the class carried out an investigation into the JPEG image compression technique. The pupils were tasked with finding out.
- Why we use JPEG compression on images?
- How does JPEG compression work?
- What is JPEG good at?
- What is JPEG bad at?
- When would we use JPEG compression?
The Pupils had to report on a powerpoint slide and include an example of a good and bad use of JPEG.
