A while ago, I saw a video about a break-beat known as the Amen break on YouTube. It’s a fascinating 20 minute slice of your life for an insight into a world you may not have a view into, that of sampling and how a single sample can go though the world. I favourited it and forgot about it. I do things like that.
Anyway, a maths professor was shown a waveform of it recently, and recognised its peaks as an example of the Golden Ratio in action, which he’s written an article about.
