Audio Capture to Micro SD

Hi, thanks for the reply. Sorry yes I am using an arduino uno r3 with a MEMS Microphone. Basically, I just need to capture a few seconds of raw audio at a time in mono with the above microphone. I have the datasheet for the microphone here:

I know when I use the "wavread" function in matlab, I get a 2 column vector of numbers which I can then analyse and plot as a graph. I was hoping I could get the same result by capturing audio from the arduino from an sd card as I know the memory is 1kb.

I've just read about the Adafruit wave shield, but this seems to playback audio and not record.

I could record the audio straight into the computer, but it defeats the object as I'm supposed to be simulating a mobile phone audio recording.
