About this app

Sound Analyzer Basic is an application for analyzing audio signals using only a mobile device.
Its main function is to display frequency (Hz) and amplitude (dB) spectra in real time, but it can also be used to display changes in spectra over time (waterfall view) and to display waveforms (waveform view) at the same time.
The frequency measurement accuracy of Sound Analyzer Basic is very high, and in a relatively low-noise environment, the measurement error is generally within 0.1 Hz. (when measured with default settings)

Main Functions
- Peak frequency display function (displays the frequency [Hz] and amplitude [dB] of prominent spectral components in real time)
- Change of display range by touch operation
- Switchable frequency axis scale between logarithmic and linear scale
- Waterfall view (displays spectral changes over time)
- Waveform view (displays sound waveforms)
- Screenshot function (with timer)

About High Frequency Range Spectrum
The app allows the highest frequency setting to be raised to 96 kHz, but settings above 22.05 kHz are for devices with high-quality audio input and are not intended for general-purpose devices.
In most devices on the market today, data in the high frequency range above about 22 kHz is filtered out. Since it is not possible to acquire data in the removed range even with a higher setting value, it is normal for the spectrum in this range to contain only weak noise of less than -60 dB.
However, depending on the model, larger noise due to filter processing may appear at certain frequencies such as 48 kHz and 96 kHz.

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 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.

I give u 3 stars to get your attention. I will give u 5 stars and buy the pro app , with these conditions : 1. Please add calibration button. If i press this button in super silent room (and i hold my breath too), the graphic will instantly flat. 2. Please add peak hold button. You can see this button in app called "sound spectrum analyzer". Its really needed. 3. Please add : range frequency settings, so i can choose certain frequency range. Example 100 Hz to 2000 Hz.
