Crazy… Those files are in the SD2 format, which can’t be read by OSX (now “MacOS”) because they have resource forks. But they can be read by an app called Sound Grinder, which will convert them with their folder structure intact to wav. The original files were 48/24. Since I own Sound Grinder and a de-archiver that can read the old Mac stuff-it format (.sit) files, I was able to download and open the sit files and convert them to stereo 48/24 wav files which are here:
I didn’t take too long, once I remembered how it all worked. Enjoy!
Edit: Actually, two of the folders couldn’t be seen by Sound Grinder, so they aren’t present here. They are the Fostex 3180, and Masterroom II IR’s. Oh, well.
