Great and fun app

This is really cool if youre an engineer or geek. Well worth $.99..

Im sure the iPhones mic has a certain frequency range, but does it really cutoff at 100hz? Would be nice if it could go lower, preferably down to 20 or so hz, which Im sure the mic isnt capable of. Maybe with an external mic the scale could shift down to 10hz?

Please make it as low as possible!
