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!

A solid state switched attenuator

Remember the great journal Wireless World? That's where I published my first articles when I started to write audio stuff. In May 1980 they published my design for a Solid State Switched Attenuator. The design was for a 60dB range auydio attenuator where the attenuation was set with a 6-dit data word. The idea was to automate it but the initial design was with a left/right up/down 4-switch array, and it never developed beyond that.

But it documents a lot of issues reletaed to CMOS switches used in audio, and how to minimize their impact on noise and distortion. Those issues are still valid almost 40 years later, because basic solid state physics is still the same!
