SUMS: Garner -- On dithering, uncertainty and loping basslines

For this week’s SUMS talk we are lucky to have as speaker Dr Richard Garner from
Macquarie University.  Pizza and drinks will be available following the talk.  

Abstract: 

Nowadays, almost every picture you see or piece of music you hear will, at some point,
have passed through a computer.  In this talk, I will discuss a seemingly paradoxical
fact: that, in turning a sound or image into a digital file, the best possible quality
is often obtained by deliberately adding random noise to your signal.  I will illustrate
this phenomenon by doing awful things to some unsuspecting pieces of music.
