Hear an Airsound system and you immediately know that it plays stereo better than left/right speakers. If it’s so obvious in practice, why prove it? Actually, how do you prove it? It turns out to be a tricky one to capture objectively. Here is my experiment which compares the systems’ abilities at producing stereo.
Yes, you can buy a DAC for less than a round of drinks, but how do these super cheap audio devices perform when compared to professional equipment? In this test, I analyse the performance of a couple of devices bought from Amazon to try to answer if they are usable, and what for?

With the recent completion of another project, and with kind permission of the brand owners, I have been able to update my portfolio for 2020. You can download it here. Continue reading “Audio Portfolio 2020 update”
A 10-year retrospective
Here are some truths:
- In every product development, something unexpected happens
- No two product developments are the same
- There is no such thing as a fixed successful method of product development
The year was 1993. I was 17 years old, and helping my father prepare for a recording we were to do on location of a choir. At the time I recall we had some of the first available low cost large condenser microphones available, and one of these had a pattern switch that allowed cardioid, figure 8 and omni directional recording. In my own work recording bands, I’d only ever used the cardioid setting, and didn’t give a thought to the ‘figure 8’ option.
In November 2018, Ted Fletcher and I gave a talk at the Institute of Acoustics. The subject was achieving higher fidelity audio through the use of Transconductance (current mode) amplifiers. I wrote this paper which is a technical approach to showing how the technology can be used to massively reduce levels of acoustic distortion produced by a loudspeaker / amplifier system.
