About this app

- Wide range of analysis parameter settings
- Frequency (horizontal axis) can be switched between logarithmic and linear scales
- Display range can be changed (zoom, scroll) by touch operation
- Automatic screen rotation (can be fixed by setting)
- Real-time display of peak frequencies and amplitudes (up to 10)

Analysis parameters
- Maximum frequency: Selectable from 2 kHz to 96 kHz (The frequency that can be set depends on the model you are using.
- Minimum frequency: 0.25 Hz, 0.5 Hz, 1.0 Hz, 2.5 Hz, 5 Hz, 10 Hz, 25 Hz, 50 Hz
- Update rate: 45fps, 30fps, 15fps, 5fps, 1fps

This app allows you to increase the maximum frequency up to 96kHz, but please note that the settings above 24kHz are mainly for high-performance microphones, not for built-in microphones of common devices.
(In general devices available on the market today, data in the high frequency range above about 22 kHz is pseudo-created by interpolation processing on the hardware. Normally, the spectrum in this range contains only a faint noise of less than -60 dB, but depending on the model, Larger noises may appear at certain frequencies such as 48 kHz or 96 kHz due to the interpolation process described above.

This app is the best! It detects bone rattling frequencies on my Skullcandy Crusher Evo's as low as 10Hz!! It has all the features you need, just one of them is missing. Holding the current lowest sound/frequency, basically a threshold for lower frequencies. Everything is perfect except for that, I love this app. 10/10 recommend it!

I'm a studio musician, guitar, keyboards, drums and I have to say I am very impressed with this apps. I don't mine the small advert at the bottom of the window, just don't start doing full page ads or my 5 star changes to a 1.

I needed an analyzer to fine tune a subwoofer using DSP. Some other analyzers wouldn't measure below 25Hz, but this one does. I couldn't tell you how accurate the decibel measurements are, but I don't need it to be. I just need to see which frequencies are lower or higher than the average so I can tweak them with PEQ filters for a level response in the 15Hz to 80Hz range and this should do that with enough accuracy for home theater needs. It reads 20Hz on a 20Hz sine wave. Good enough for me.
