I am using pydub to split an audio file, giving the ranges to take segments from the original.

What I have is:

from pydub import AudioSegment

sound_file = AudioSegment.from_mp3("C:\\audio file.mp3")

# milliseconds in the sound track
ranges = [(30000,40000),(50000,60000),(80000,90000),(100000,110000),(150000,180000)] 

for x, y in ranges:
    new_file = sound_file[x : y]
    new_file.export("C:\\" + str(x) + "-" + str(y) +".mp3", format="mp3")

It works well for the first 3 new files. However, not the rest - it doesn’t split accordingly.

Does the problem lie in the way I give the range?

Add-on:

When it's made simple - for example

sound_file[150000:180000]

and export it to a mp3 file. it works but only cuts 50000:80000 part. it seems not reading a correct range.
