trimp3, the best free command line tool for cutting and trimmimg mp3 files in Windows. It is a simple command line tool specifically designed to trim MP3 files without decoding and re-encoding, thus maintaining the original audio quality. It works by copying portions of the MP3 within the specified time range internally but hides the complexity behind an easy interface.

Step 1: Install trimp3 globally using npm.

npm install -g trimp3

Step 2: This tool is efficient, fast, and keeps original audio quality intact while trimming a mp3 file.

trimp3 input.mp3 output.mp3 beginTime [endTime]

input.mp3: The original MP3 file.

output.mp3: The trimmed MP3 file to create.

beginTime: The start time of the segment you want to keep (in seconds or mm:ss or hh:mm:ss format).

[endTime] (optional): The end time of the segment (same format as beginTime). If omitted, the trim will start at the beginTime and go to the end of the file.
