Development of functionality to work with unencoded audio files

This article discusses possible scenarios with uncoded audio file in wav format, PCM (Pulse-code modulation). The paper deals with the methods of reading data from a file, methods of building a frequency-wave spectrum, methods of changing the amplitude of the wave audio file and methods of saving the result. A simple audio editor was created as a result of this research. It can be useful as a base for the development of software solutions in the field of working with sound.
