Slaying Dragons #14 – Digital Deflation

John Watkinson considers deflation in the digital world. Since the economic crash of 2008 it has become clear that it was not a temporary event, but a correction whose results would be near permanent. Corrections take place when the wrong road has been taken for too long. In this case the wrong road was excessive…

Slaying Dragons #13 – What is Science?

I got to thinking about science, and how much better my life has been because of it; how much better things work. Yet I realise that I am in a minority and that we don’t live in a scientific world. Am I a scientist? Frankly no; that word doesn’t describe me. My life is not…

Slaying Dragons #12 – Is Digital Automatically Wonderful?

John Watkinson wonders whether digital is automatically wonderful. I have lived long enough to have seen the so called digital revolution take place, not just in audio but in life. In one sense I feel very fortunate to have lived through that era and to have made a living documenting it. Being in the right…

Slaying Dragons #11 – Computer and Network Security

John Watkinson wonders about computer and network security A long time ago when Pontius was still training to be a pilot, it was possible to consider audio as a separate topic. Today such a separation is impossible. Audio is just another form of information that can be conveyed over some network or other and we…

Slaying Dragons #10 – A Fan of Analog

John Watkinson is a big fan of analog audio. An analog is a phenomenon that behaves similarly to another. In speech we have similes and education is full of parallels. Whilst a painting or a sculpture can last thousands of years, in audio we have a problem that sound cannot be preserved at all in…

Slaying Dragons #9 – Radio History

John Watkinson relates a personal history of radio. The family radio in the kitchen churned out uninspiring stuff most of the time, but I remember in 1962 it emitted a song called “Love Letters” by Ketty Lester, and when I listened to it I felt, probably for the first time, that here was a song…

Slaying Dragons #8 – Rational

John Watkinson tries to be rational. Sometimes I like to discuss topics that are not immediately identifiable with audio. Audio is part of the world and is not the only discipline in which excellence is pursued, and achieving excellence by rejecting the mediocre takes place in many other endeavours that are worthy of study. We…

Slaying Dragons #7 – Transforms

Transforms are very useful in audio, but John Watkinson argues that they are just as useful for understanding audio as they are for processing it. Let’s look first at the Fourier transform. The whole basis is that any periodic waveform can be broken down into a set of harmonically related pure tones, or sine waves.…

Slaying Dragons #6 – Where now for Audio?

John Watkinson looks at evolutionary forces. Nothing is for ever and the only certainty is change. The endless march of evolution in the biosphere is paralleled by evolution in technology. The audio industry is only part of the world, yet the extent of the changes that have been seen in audio are such that they…

Slaying Dragons #5 – Audio as Information

Photo John Watkinson

John Watkinson looks at audio as Information Allegedly we now live in an information society. I don’t accept that. In fact there has been information for as long as or longer than there has been society; indeed the cohesion of society depends upon information. Optical fibres descend from the use of smoke signals and semaphore;…
