Okay, I realize that this is really left field, but I have to ask...
Is/was there such an animal as a microphone that was designed and built to interface to a Mac serial port?
I trust there would probably be special software for such a creature to function, so this would be helpful to share if you know as well.
In the event that none exists, what must I do to build my own?
I have never done anything like this, but I have a special application for which a serial based microphone is the best possible soultion. If it exists, that helps, if I must build it, that sux, but learning could be fun.
