Understand audio editing
While there are many programs available that are specifically designed to automatically split an mp3 into multiple tracks, you should consider learning how to edit audio files yourself. This will be a more versatile and ultimately more valuable method than using a specialized program.
You need to get a program that can do digital audio editing. There are many commercial programs used in professional recording that suit your purpose, but there are also a few more basic programs (GarageBand is one such program, which comes standard with many Apple computers, Audacity is an open source audio tool). In an audio editing program, you can open a file and visualize a song’s waveform. It allows you to manipulate an individual file.
Open the mp3 file in your software. see the song’s waveform, which allows you to visualize the dynamic track of the song. Treat the song as a text, from which you will cut parts. Find the first desired track and select it with the program’s selection tool. You can then edit the track as if you were editing a document. ‘Cut out the first track.
Now you want to create a new audio file within the program (do not save your changes to the original, if you make a mistake). Once you are in a new file, select the ‘Paste’ function and your selection will be displayed. If desired, you can then edit the new track. For example, it is often useful to apply fade-ins and fade-outs to the beginning and end of a track, respectively.
When you have finished editing the first track, save it as a separate file and then repeat this process by opening the original mp3 for as many tracks as you like. Note that this is also a valuable technique to use if you need to cut one as large as to send as an attachment or too large to fit on an audio CD. In the world of digital music, an mp3 file is often a single song. But sometimes an entire album is grouped in an mp3 file. In such cases, the file can be divided into several tracks. This allows the user to easily access individual songs. This method can also be used to divide a single song into several different tracks.
