The only problem with using any app. is the fact that no matter how fine the code is written, at the end of the day your still at the mercy of whatever your using collect data. In this case, conduct the vibrations to your device. All vibratometers I know of come with a dedicated "probe" just for vibrations. So what your doing is basically trusting the 23 cent microphone in your phone. Would you trust a frequency analyzer app to do room correction? If you do your probably going to have a dead spot below 40 Hertze. Why? Because your phones mic cannot read at that level.
>>>>>Huh? Whoa! A microphone? I’m afraid the microphone does not (rpt not) have anything to do with it. The microphone is for acoustic waves, you know, like voice, not (rpt not) seismic or mechanical vibration. The accelerometer in the phone is the device that detects and measures mechanical and seismic type motion, for example when you turn your phone on its side, the phone’s accelerometer detects the motion and corrects the screen display orientation accordingly. So the accelerometer(s) measures acceleration and by calculation velocity and direction are obtained. There are several reasons why some or most of these vibration apps won’t work for seismic vibrations, including but not (rpt not) limited to the fact that speakers do not (rpt not) produce any mechanical feedback below say 25 or 30 Hz.
Two turntables and a microphone....where it’s at?
