I'm wondering if there's any way of recording low frequency noise, bass specifically, with a just the capabilities of a phone. To give y'all a better idea, I've got a neighbor that sucks in all the stereotypical ways, constantly playing loud music, raucous late night gatherings, etc. What is most annoying, is the music, or more specifically, the constant thumping bass that manages to travel through the walls. Its loud enough to hear with the naked ear, but not loud enough to pick up on a mic and then play back in a recording. I know its a strange request, but i need legal proof that they are ignoring the formal complaints that have already been presented to them. Basically, i'm inquiring about the most affordable course of action. Since I'm sure some one will ask, I'm using a Samsung Galaxy S3. Side question: it occurs to me as i'm typing this, that there is the possibility of my phone not having the initial ability of even being able to pick up the noise. If that's the case, is there a way to boost its power and/or affordable alternatives.
