sinewave application

[spike00olds]

hey, im looking for a modification of sorts,

i like alot of my friends have subs in my car, and often times i like to play test tones which are used alot in DB drag.

well when i saw the sinewave app for my ipod i was excited, but come to find out that it only goes down to 80hz.

my request is if someone could make an app, or modify "sinewave" to go from 10hz - 200hz and have 2 buttons, one being a momentary switch when you hold the button on the ipod (not the home one) it would play the tone selected on a slide bar (or preferably a digital # pad input) and one button be a toggle so it continues to play after being switched. any help would be great

sincerely

is the phones mic even close enough to be able to capture that range?

no, i mean i want the phone to output a sinewave tone of my choosing ( the frequency that is) with a momentary switch and a toggle
