Twisted Wave on the iPad with the iRig microphone

This morning I have bought the application Twisted Wave to use on the iPad for recording audio. I have the iRig microphone which is a very good microphone for using with iOS devices and I have compared it with recording directly into my iMac using a Sampson condenser microphone. I am quite pleased with the results from the iRig microphone on the iPad, it just needs a little bit of tweaking to give it a richer more for sound. I can do this by applying a couple of filters and may be using a dynamics processor.

Most often I record my Audioboo's directly into my iPhone and while I am out walking the dog, but sometimes it is quite nice to sit down as the computer and use good software and better microphones.

What sort of microphones are you use when you are recording your Audioboo's?
