Recording Studio

Obviously I know that this isn't the most ideal way to make a recording studio but I figured it would be cool to try... Is there a way to buy a wireless or wired microphone and hook it up to an Arduino so it can record singing and then save it to somewhere and replay it later? what would be the best way to save the recordings? Also, I have built one of those beat boards (launchpads), is there a way to automatically put that in the background?

Thanks,

An Arduino is a microcontroller. It was designed for controlling IO: read buttons and sensors, drive LEDs or motors, etc. It is not suited for recording, storing or playing audio.
Its ADC is way too slow for recording high-quality audio, it has not nearly enough memory (both RAM and permanent) to save or encode the recorded data, and it doesn't have a DAC for playing it back.
