- Stand (obv :D)
- Something to basically connect the mic into computer (via usb or firewire)
example:
http://line6.com/podstudioux1/Tons of this kind of audio interfaces exist.
(Required cable to connect mic to your audio interface, that would be the line6 in this case. Obv. :D)
- Software required to run the interface, usually comes with the package and / or is downloadable from manufacturers homepage.
- Software to record your piece. There is also tons of recording programs, go for a free one like Reaper. Its decent enouch for you.
Other good ones would be Cubase, Nuendo, Pro Tools, Logic, Ableton etc etc.
That should do it. Total cost ~100$, unless you DONT have the microphone yet.
