I am hoping someone perhaps could point me to an application that works on the iPhone 4s or iPad 3 that will do all or some of the following -
Meter db levels
record audio from 20-20khz along with frequency range of sound
My goal is to record "noise" levels that exist in a building. It would be useful to be able to tell the frequency levels of the noise, in particular 17-100 but 20-20khrz would work well enough and if possible to stay on for a few hours so that inconsistent noise could be recorded for duration, frequency as mentioned and db. Most of the noise sits at the lower end in the frequency range and I don't know of any app that does the above.
Any help would be appreciated and if this is not available, is there an inexpensive alternative? The noise is mostly coming from a mechanical source and it includes typical audible sound, humming and noise sitting at the infra-sonic range (vibrations etc.).
Thanks in advance.
