MP3 Cutters: Split MP3 Files Into Multiple Audio Tracks and Vice-Versa

DI Reader Ashish Gupta has an interesting question - "Do you have any easy to use freeware to split mp3 file into smaller mp3 (at user defined points)? I know Virtual Dub that does same to video files."

MP3 Splitter utilities let you easily trim the not-so-interesting portions of a podcast show, music recording or even a CD song. This reduces the file size and your friends won't get bored as they get to listen only the relevant parts of the audio clip.

While there are tons of free and commercial MP3 Trimming software, the most popular ones are MP3Splt and MP3DirectCut - both are free and keep the music quality intact as they directly in the MP3 format without having to decode/re-encode.

Command Line Utility for Splitting MP3 files

MP3Splt is a free but amazing command-line utility that can split mp3 and ogg files from a begin time to an end time. MP3Splt can even detect silent points in your audio clip and split the track accordingly.
