A Mr. Randy Harris comments about Voice Candy at MacUpdate:
I've been using Voice Candy for a few weeks now and I really like it a lot. I bought it with the intention of using it like a voice version of Apple's PhotoBooth, which my kids love.
After using it a little I quickly realized that Voice Candy is about the best and easiest to use Voice eMail program that I've run across.
This put a broad grin on my face because while the effects are cool, we really wanted to make a general purpose voice recorder that is useful in addition to being fun. It is satisfying to see someone reaching that conclusion.
In any case, there actually is something helpful in this post.
If you are sending voice emails (or really just any attachments), like Mr. Harris here, and some of your recipients are Windows users, you will want to do this in Mail.app:
If you don't do that, Mail.app will send two attachments: a "Recording.mov", which is the real thing, and a "._Recording.mov"—what we have come to call the "shadow file".
"Uhm, Randy... I get no sound?", will be the response you get invariably because for some reason, they never click on the real file first. Part of the reason is because the shadow file shows up first in the attachments list. The other reason I won't say out loud.
So what is this shadow file? Why is it there? Well, the file contains resource fork data. Windows users have no use for it, and frankly, I don't think Mac users have much use for it either these days.
