My friend needs to be able to record preferably 5 separate audio sources to separate audio files on an sd card, using the sparkfun sound detector (EN-12642). We know absolutely nothing about Arduino and have under a month to get this working. He's in rockets through his 4H group and they need to record 5 (or 3, if 5 isn't possible) for the duration of the flight. someone help please!

sample rate?
bit depth?
sounds challenging without a native SDcard interface.

The Arduino isn't really optimized for audio recording (or playback).    I know people have tried  to make a recorder, but it's really not a job for a beginner.

...I'd look for a stand-alone sound recorder chip/module that doesn't need a microcontroller or software.

From 5 sound sensors???   I can't imagine why you'd need 5 channels from a model rocket or that you could even get a useful 5-channel recording, especially with no fixed/controlled orientation and omnidirectional microphones.
