Description
The Test is done at many different frequency so to produce the graph of the audio path response.The purpose of the Test is to compare the audio path gain of a system composed of an amplifier and loudspeaker but you can test also only a loudspeaker or earphone. The phone generate a list of tones(frequencies), the signal is acquired from the microphone and the relative power is calculated for each frequency. Please note that 0dB is an undetermined value so the measures are relative and not absolute values.
A teacher used this App to do an experiment in his class, he was able to find the speed of sound using a phone and a cardboard tube. Determining the loudest frequencies, then these are the resonance frequencies and will lead to the speed of sound because the length of the tube is related to the wavelength of the resonant frequencies.
The tests are in the internal directory of the App to improve compatibility with Android 10 (Android/data/com.fbrlcu.audiotest)

Questions & Answers
Q: What is an APK File?
A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.
Q: If I install an APK from this website, will I be able to update the app from the Play Store?
A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.
Q: Why ApkClean.net can guarantee APK 100% safe?
A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.
Q: What are Android App permissions?
A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.
