That's not necessary today. Look how cheap USB keyboards are. Many microprocessors in the $1 class can run slow-speed USB just fine. Microphones should use USB for their button interface, and implement the HID protocol as keyboards, mice, dials and joysticks do. This allows the device to discover what's plugged into it, and use it appropriately. You can also digitize voice right in the microphone, and use the standard USB connector.
For an example, see http://www.americandictation.com/olympus-dr-1200 They don't really have to cost $250 the way that one does. Thanks Bruce
