About this app
Turn your phone into a Spectrum Analyzer. Speccy is an Audio Spectrum Analysis tool, which visualizes the spread of frequencies detected by your microphone. It uses an FFT signal processing algorithm and supports the most languages of any similar app. It's also the only app of its kind allowing you to export audio snapshot data to the clipboard, for plotting in Excel, etc.
It has a wide range of uses, such as: assessing environmental noise, tuning speaker systems, identifying audio signals obscured to the human ear by noise or simply testing the microphone on your device. You could use Speccy to compare the quality of different types of headphones, test signal generators or measure audio signals just outside human perception. It apparently has also been used successfully to find gas leaks.
Speccy provides the most 'analysis window functions' (the 13 most popular for audio engineers) and, for your added peace of mind, the only permission Speccy needs is microphone access.

Beautiful piece of work, very configurable. It's a real–time audio spectrum analyzer, I'd say professional grade, although reading exact peak frequencies could be easier, perhaps. Non–technical people might want to learn more; such magic happens when deep understanding gives us such as this. Nevertheless, the essentials should be self–evident.

Thank you. I'll have a think about the easiest way to enable an exact frequency entry field for the 'inspector line'. Though bear in mind that a Fourier Transform is a mathematical model of the weight within a given frequency band. Setting the highest 'FFT length' of 16384 gives a resolution of around 3Hz. Higher than this might be impractical.

Appreciate the efforts that has gone into the making of this feature rich app. The two finger swipe option for zooming the frequency scale is quite useful. Would like to suggest a couple of additional feature that may be added: If it is possible to add more number of marker lines by the user for the frequency scale, people like me can use this app for extracting notes from the bass line of music. Also, if possible, displaying the musical notes on the peaks itself will be extremely useful.

Nice idea. Displaying notes (at concert pitch) in the peaks. I'll look into doing that :)

It's a good app so stop looking at the 1 star comments also if it's not 100% accurate, you can normally adjust settings till it is. Be respectful with your comments cause last time I checked even if it's 50%, that's more accurate than your one (Unless you've actually developed one and are testing others then that'd be kinda funny but regardless)
