Welcome to my place!

Audio Resource Jan Didden

It's great to have you here!

This place is where I talk about my personal projects, interests and whatnot. Not necessarily related to audio, although it often is. Under the Musings button you'll find things related to perception and conciousness which of course are very much applicable to audio!

My library lists lots of (historic) audio papers and studies that I personally find important to understand many different issues in audio.

I also have collected the interviews I've done with audio luminaries. Take some time to read and digest them - there are very interesting and worthwhile gems in each of them! My projects however is audio stuff - things I designed, wrote articles about, and my personal system. Comments and remarks are always welcome!

Last but surely not least, let me mention my publication Linear Audio. Published twice per year, over 200 pages of technical audio related articles from international authors. Article abstracts and author bio's can be read at the website, and some articles are available for free online.

So, take a look around, explore the various areas and let me know what you think!

Cyril Bateman's Capacitor Sound articles

Update April 2017: I was made aware of another large zip-repository of Cyril's work. Thanks to Kevin Thompson and Sebastion Veyrin-Forrer. 

During 2002 and 2003 Electronics World published a slew of articles by Cyril Bateman on capacitor distortion, dielectric absorption and several other subjects. The series also detailed his purpose-build test equipment and was published under the title 'Capacitor Sound'.

This was a landmark series and is still read and consulted frequently. I asked Cyril to write an update for Linear Audio, addressing new findings and products since the publications of the series, and he kindly agreed. The new article appeared in Linear Audio Volume 9. Sadly, Cyril passed away early 2015 after a life of contributing to technical progress.

As a backdrop for the new material, Cyril has kindly agreed (and the Editor at Electronics World has kindly allowed) to post the original articles on this site.

So here they are - enjoy the read!
