It is necessary to record sound in WAV format, forming a waveform according to a certain law. I figured out how the WAV header works, but I don't understand how the sound is recorded in any way. I chose a 32-bit recording per sample, here is an example of sample from a real file:

55 73 0A 0D 32 33 30 3D

In theory, it should be a fractional number from -1.0 to 1.0. There are questions: how is the sign stored here? I also wonder where the comma stands here.
