United StatesTurn 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.
Great!
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)
Bought this app in 2018, skip forward to 2024, and it works perfectly, easily, and does exactly what I want if it. An easy 5/5 for both the app and the dev.
It does everything that I need it to do!!!
Not very accurate or consistent, playing the same tones in a sound controlled environment is showing different readings.
An excellent App. I really appreciate how easy it is to record and output a spectrum for further analysis in other software. I also greatly appreciate that the author, having been told that the App didn't work for a version of Android, pursued the problem tenaciously until he solved it - just the kind of attitude which deserves to win and retain a good reputation. Thank you.
Works well, no ads, what else can I say
