Welcome to MP3extractor.
This script was created with the aim of simplifying audio extraction with the "ffmpeg library in mp3 format from all the mp4 files present in a folder. Obviously it allows the choice of the input and output folder and the quality of the Bitrate and Hz. The script is constantly updated.
Unfortunately, an installer with a launcher has not yet been created.
Note
You can use the script by starting it from the terminal.
