I would like to build a recording software, for my own purposes, I would like it to be deployable on multiple systems (Windows and Unix) I am also building an application first time. So any help you would be able to provide on that topic as well it would be appreciated.
Please and thank you.

I haven't seen any API for dealing with Microphones explicitly, but the Java Sound API should be able to see it as an input. Specifically, the javax.sound.sampled classes.
Oracle has a (not-so-quick) Java Sound Programmer Guide which includes Chapters on Accessing Audio System Resources and Capturing Audio.
