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…

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.…

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…

John Watkinson wonders if accuracy in audio actually matters. I would have to begin by defining what I mean by high fidelity. What I have in mind is a system of sound reproduction that is so realistic that it is indistinguishable from being there. However, the more I think about such a system the less…

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,…

  Real time is one of those phrases that bounces around without it being clear when it applies and what it means. Once upon a time there was analog audio, whereby an electrical waveform was an analog of sound pressure or velocity at a microphone and could produce sound again at a loudspeaker. There was…
