Output of the audio file when using wavfile.read() does not originate from zero

All of my audio files that I am using producing an output that does not make sense for me when using wavfile.read() I do not why. For example output of one file is

why is it not originating from zero like a normal audio for instance :-

I wanted to ask why my output in the first link is not read normally and how to display it normally so I can analysis the audio properly. I have been searching for a couple of days and could solve it so I would appreciate it if someone can guide me or provide me with useful links

It seems that it depends on the library that is reading the audio file which can produce different outputs, I shifted to read my audio files by:-

import soundfile as sf
data, samplerate = sf.read(audioFile)

and now the output representation is originating from zero.
