mp3-split is a command-line utility that splits a long MP3 file into smaller files and then tags them with the track name and track number.
It depends on Python 3, ffmpeg, eyeD3, and mp3info.
It was developed on Linux but may work on Windows if the dependencies are all in the PATH and if the script is called from the command line by python mp3-split <arguments> or python3 mp3-split <arguments>
Also, you can try to use the WSL (Bash on Ubuntu on Windows)
Usage: mp3-split MP3_FILE SPLIT_INFO
Example SPLIT_INFO file:
01 Track Name 1 0:00
02 The Second Track 3:26
03 A Third Piece 26:01
