Android App of the Week: DecibelX

I haven't done any reviews of Android apps in a while. That's mostly because I haven't been downloading many; I have about 200 installed on my phone already. Still, every once in a while I come across something worthwhile.

Decibel X is one of those worthwhile apps. It's a noise meter and a very nicely designed one. I haven't gone through all of the options yet, and probably never will, as there are quite a few of them, some of which would be of interest only to professional audio engineers.

A few of the key features:

• Trusted accuracy: the app is carefully tested and calibrated for most devices. The precision is matching with real SPL devices
• Frequency weighting filters: ITU-R 468, A, B, C, Z
• Spectrum analyzer: FFT and BAR graphs to display real time FFT. Those are very useful for frequency analysis and musical tests. Real time predominant frequency is also displayed.
• Powerful, smart history data management:
• Recording data can be saved into a list of history records for future access and analysis
• Each record can be exported as hi-res PNG graph or CSV text via sharing services

This should be handy for measuring the volume along our street, which seems to be a haven for testosterone crazed drivers with big engines and small brains.

There is also an IOS version for those of you on the Apple spectrum.
