Great App to Analyze a Strange Noise in Home

We had encountered a buzzing noise that came and went. The noise was coming from the ceiling my office like it was originating in attic. Was it a bee hive or hornet infestation, wind causing vibrations in eves or loose roof components or more serious issue some kind of electrical hum or buzz. I thought if only I had a spectrum analyzer I could rule out an electrical issue if the noise was 60 HZ or a 120 Hz harmonic. So I thought my phone has a microphone and it certainly could analyze sound . So I found this App for my iphone.
It showed the primary vibration was 101 HZ so I felt relieved. But what was it? The room next door was a bathroom and the noise was louder but still coming from the ceiling. So then I thought toilets can cause funny noises. I took off the tank lid and waited until the noise was loudest and touched the float arm hitch was connected to the auto shutoff valve . It was vibrating like crazy and the noise went away . But I still could not understand why the noise was coming from above. Then I thought the plumbing stack vent was just like a pipe in a pipe organ. The vibration in the tank made the column of air in the stack vent resonate.
Strangest annoying sound and plumbing issue I have ever heard of in my life. I fixed it by turning the float adjustment screw just a bit.
The technology in a smart phone seems to be unlimited.

Works Great

I use this to help ring out every room before performers ever get to the show. Maximizing gain before feedback is as simple as pushing the fader nice and slow until you hear the ringing start, then the app tells you exactly what you need to take out. Invaluable if you don’t have a digital mixer with a spectrum analyzer built in.

Developer Response ,

Thank you for your review. And absolutely great way of using the app.

Clean Design... but wanted Line In option

It gets four stars because IF you only wanted to use the not so great built-in microphone of your device then it seems to work very well. I was actually willing to pay for a way to unlock a Line-In feature but nothing told me that the feature exists. The fact that the spectrum plot can hold the peaks is a real nice and makes your app more useful. The pop up is super annoying, but being an App developer myself...I understand how selfish people just expect a great feature rich App to be all for FREE (i gave up thinking i could be paid for all my hard work). Just for fun, you can check out my Free iPhone App FlipNshare ProVideo. I did uninstall the app only because i need Line-In feature, please let me know if it’s actually available.
