09/04/2017 | 0 Comments

Where is it all going? John Watkinson fails to learn from history. Nothing is for ever and the upheavals we have seen over the last decade are a taste of what is to come. Those of us who work in audio often do so because it’s a bit different from the rest of the world,…

15/01/2017 | 2 Comments

John Watkinson looks at the relationship between science and beliefs in the context of an on-line society. Audio is not a world of its own, it is part of the world, and as such displays characteristics that have parallels in the rest of the world. Like any high-tech industry, today’s IT-based audio industry depends totally…
