Have you gnawed to an unnatural attenuated sound by auto gain control?
If it is a Android 7.0 or later model this application may be able to solve that problem!
(Android 6 and below will not work!)
By not carrying out preprocessing, the volume goes down and noise tends to occur, but it can be controlled anytime later.
The motive for development is that the sound of ZenPhone 3 Ultra you use is too bad, thinking you can manage it somehow and as I looked it out, I noticed that a certain number of people have this problem.
However, I am an amateur of the level "What is java?" One month ago. There might be a problem etc.
In case
This application uses a wonderful open source application called Easy Sound Recorder. How to use is the same.
However, Raw Sound Recorder is the only application that does not use auto gain control.
So, Easy Sound Recorder owns copyright and other things other than being able to select unprocessed audio.
Easy Sound Recorder's name will also appear frequently in the app, but the original was Easy Sound Recorder.
