Welcome to the Thunderstone Audio Website!
Welcome to the Thunderstone Audio Website!
Thunderstone Audio is what I call myself and my "company" for my audio interests. Currently Thunderstone Audio has not got any products for sale; this may change at some point in time.
Thunderstone is the English rendering of my name, Thorsten. Thor - the Norsk God of Thunder and Sten - the Stone.... So just for fun I included above a picture of a Norsk Amulett depicting Mj�llnir, Thor's might Hammer. Well, now you know why "Thunderstone Audio".
This website really exists only for one reason. Over the years I have produced quite a number of Projects in audio and usually have shared these in one way or another with those interested. Due to a number of reasons this output is widely distributed all over the web. In a number of cases I cannot provide updates to projects on the original sites. Furthermore I regularly get e-mail's moaning "why don't you have all your stuff on one single website, it is so hard to find anything.... So here it is. In the coming month I will start to add material to this site, as, when and if I find the time to do so. For now you will find some very basic info on current projects and collected web pages from previous projects of all sorts. You won't find any flashy graphics or fancy layout, just straight info.
You will not find here at any time a links list section, so while I appreciate anyone placing links to this site on their pages I cannot in return link back. Allmost all links will appear in line in the text only.
There are really only a few links I just had to include here.
