Enion. Sound Meter

             Working as an engineer often has to deal with construction, one of the engineering tasks in my profession is the device of the pile field under the building, during pile driving a hammer blows about the pile, it's a pretty loud sound, the number of strokes per pile can reach 500, counting engineers are knocked off the account and the discrepancy can be in the hundreds of strokes. And once standing, at the foundation pit of the future building, I decided to write a small program for myself and for entertainment, as they say "just for fun". The application implements the principles of machine learning. During the creation of the application, I encountered various tasks and decided to test it on music tracks where the sound wave is much more difficult and it is much harder to capture the peak values.
