Sound Designer II Files will not open.

Post by mtunze »

When I try to open my .sd2 files I get a dialog that says: This file does not seem to be a valid SoundDesigner II audio file.

They were always valid before. This happens on my studio iMac running Mountain Lion and on my laptop running Catalina.

Hi, could you send me a link to a zip archive containing a couple of sample files?

Also, please do move over to a different format. SD2 is based on resource forks which have been deprecated by Apple for years now (since 2009 in fact), so there *will* be a version of macOS at some point (and probably sooner rather than later) that *will* break them. Regards,

Martin

Thanks for your response. I figured .sd2 was on it's way out when most of the competitors audio editors don't list the format.

I have .sd2 files going back to 1994. I did find a converter.

I'll get you a file or two over the next couple of days.

Also I noticed that in trying to open .sd2 files, the files I tried to open became unreadable after trying open. The size on one file went from 250 meg to 266 bytes. The converter I found wouldn't recognize the file afterwards. It recognized .sd2 that I had not tried to open with Amadeus Pro.

OK, the version at

http://www.hairersoft.com/Downloads/AmadeusPro.zip

should now again open the SDII files correctly. You should also be able to use it to batch-convert them to a more stable format (I would recommend AIFF unless the files are larger than 2GB in size, in which case CAF is better). Regards,

Martin
