measureing frequency and ampliture with an iPhone app.

Hello, I need to create a iPhone app to:

a) identify and measure the frequency and amplitude of a rhythmic vibration in the 2-20 htz for a fixed interval of time (ie 10-20 sec)

b) and provide a moving average of the frequency and amplitude over a time period. For example it may be over 30 sec with a moving average over 3 sec.

It helpful if you are familiar with accelerometers, particularly the iPhone’s . If you can program it yourself even better.

([url removed, login to view] features/[url removed, login to view] ) and yes I am aware of the opensource apps that record accelerometer data and display it.

We can program our selves, but are not quite up to par with the math and physics. So we will probably be utilizing high pass filters w/ FFT.

I’m looking for someone with experience in these type of measurement w/ accelerometers, the math & the programming. If you have experience specific on the iPhone even better.

Thanks
