Audio Analyzer
Audio Analyzer is the App that allows you to perform some technical measurements of quality of the audio equipments such as amplifiers, pre-amplifiers, loudspeakers, headphones, receivers, microphones, equalizers, mixers as well as the whole audio track that including all of these audio components. Also the App is capable to measure audio parameters of separate electronic circuit components such as filters, transformers, operational amplifiers in the frequency range from 20 Hz up to 22050 Hz.
The following audio characterictics can be measured by this App: frequency response curve, dynamic range, harmonic distortion, intermodulation distortion and other non-linear distortions.
The idea of the App consists of receiving the input feedback audio signal and compare it with the output audio signal that the same Android device is generating.
The App is capable to form the output audio signal with practically ideal rectangular spectral characteristics in the user-defined frequency band in the two separated bands plus some fixed frequencies simulanuesly.
It takes less than one second to build the frequency response curve in the full audio range of 20-20000 Hz in 2.5 Hz resolution with the wideband audio signal generated by the same device.
An input and output of the signals are provided through the audio jack of the device. The microphone line is used as the input, the headphones line as the output.
Features.
Completely NO ads.
Selectable frequency resolution between 2.5 and 10 Hz.
Separate analysis in the left and right audio channels is possible.
Fine-detailed viewing the frequency response spectrum with up to 16384 spectral points by zooming and dragging.

This app is good but I'm looking forward to seeing you guys making another app . By chancy from Malawi
I see an idiot review that says this app sends recorded conversations back to the developer but that reviewer must be nuts. Test the app and you'll find that it does not have internet access! None!
All I can say is, A HUGE THANK YOU TO THE DEV 😉 👍🏻, and can you please please please please, keep up your fabulous work.. Thank you!!
Doesnt work for me errors blocked apps 2021
Extraordinariiiooooooo absolutely fantasticoooooooooo thank you for sharing this app
Must fully check things out
INEXPERIENCED USERS BE CAUTIOUS! This app detected all sounds below human hearing levels (negative decibel range) emitted from devices connected to your home/business wifi/Bluetooth (including all recorded conversations not disclosed in developers description) and sends them off in to developer via encrypted text/calls/emails. Otherwise, beyond this warning, app does what it states. And then MORE ...
Sergio makes good audio/mic based products. Spectrum display responds appropriately to various sounds, so I don't see how a user can write it off as "bull". Good app coding and aesthetics.
Best of lak.dosto
Its Great
Bull

Not well writen. App can not be moved to external SD memory
My phone's hardware limits the use :-(
couldn't tell how to use it and another thing is pleas don't have it start out at 15000 that's head ache inducing...
The best aa I think the best of this app
Thanks again and I look and let me tell me and I'll send it to you in the morning and then I will get it in and out and let me tell me and I'll send it to you as soon as I get home.
Only detected its own noise, useless. Why was it creating sound? Or is that the only thing it analyzes?
I have no Idea how to use it. I am working with a wired earplug phones with inline push button mic. Any help.???
Short and simple distribution and quality
I enjoy it to the fullest
Nice invented
This is a GREAT app, I have used it for quite a few months, and it is ACCURATE! You could probably use the app in a hospital, the doctors would have a problem with that.
