Audio copy methods and their uses were examined in Conor’s class.  The differences in sound quality and sizes when compressing by bit size, 128, 192, and 320.  Also the comparison with wav download.   Sizes of files varied from 2.9 , 4.7, 5.8 to 25.9 MB for the wav.   These were lossy compression with the exception of wav which is a lossless compression which copies sound and quality exactly.   This is however a much larger file.   Previously due to storage sizes the mp3 was the best option for compressing however now due to larger storage options i.e terrabyte etc the wav format will allow better quality music with no loss of sound etc.

We also disucssed different formats and methods for compressing audio.   The origins and the first mp3 song Tom’s Diner by Suzanne Vega.

RADAR People of the Year Human Rights Awards 2010

December 7th, 2010

On Monday 29th November 2010 despite the deep snow and travel disruptions I managed to get down to London to attend the RADAR PEOPLE OF THE YEAR HUMAN RIGHTS AWARDS.  I, alongwith other young members of the Council for Disabled Children Steering Group had been shortlisted for the Young Person of the Year Award. Whilst we did not win the award it was a real honour just to be there on the night, with lots of inspiring speakers, fine food and glittering lights.  Please have a watch of my video from the event.
