(sigh) I think this thread is referring to Jörg Wuttke's essays on microphones, which Schoeps published ~15 years ago as a printed softcover book, and later made available as downloadable PDFs. I translated the essays back then, at least to a preliminary level, but have lost track of the project--I think there was some reason that they didn't get printed or turned into PDFs at the time, or maybe we simply never finished reviewing them all.
Then Jörg retired from the company and set up his own Web site (on
ingwu.de) which carries the essays as PDFs in German, but not in English.
He's coming over for the AES convention in October and I'll see him then--maybe we can revive this project. Some of the essays are of less interest now than in the past (some are based on Schoeps products that are no longer available, such as the original PolarFlex system which he invented and patented), but the majority should still be worthwhile.
Also, he's made a number of educational presentations that have been recorded on video and uploaded to YouTube, and if I remember correctly, he gave at least one such presentation in English. Those are quite good--he has fun with an audience.
