Moschops Posted December 17, 2018 Share Posted December 17, 2018 Fourier's theorem is one of the most useful facts in many branches of physics and engineering.This video shows how all complex waveforms (sawtooth/triangle/square/cranial) can be constructed from the simple addition of sine waves (a graphical reprasentation of circular motion). Doing a bit of digging on the subject I discovered reference to a famous paper by J.W. Cooley and J.W. Tukey from 1965. Their work utilised Fourier analysis and led to a radical increase in computing speed by exploiting the binary notation inherent to computers and the symmetry of sine waves. This leap in computing power is what enabled the effective storage and recall of analogue recorded sound via digital bits of information. Nice one lads!

mfsop Posted December 17, 2018 Share Posted December 17, 2018 I had to calculate these suckers by hand some years ago - glad that's no longer necessary!At the time I was wondering if Final Scratch or Serato used them too but never googled it. Well, here it is: http://www.esgrove.fi/analysing-the-serato-dj-timecode-signal/ Quote Link to comment Share on other sites More sharing options...

Guest It'sPhilFromThursdays Posted December 18, 2018 Share Posted December 18, 2018 This is great, i dun this at mind school, too, but just dicking with the basics. I love that graphical representation that dude has made up, that makes it so simple to understand for our mind's brain's thoughts. Quote Link to comment Share on other sites More sharing options...
