MP3 is a very popular music format which can be played on multiple multimedia devices, such as portable music players, DVD players, smartphones etc. Often, depending on different purposes of using this common audio file, we need to do some basic editing work to fulfill our requirements, such as joining a bunch of MP3 files into one larger file or splitting long files into small segments.

In this article, we will introduce two different ways you can use to merge several songs into one single track with ease:

• 1.Mix several MP3 files by using the Command Prompt interface in Windows(Windows only, free)
• 2.Merging MP3s by utilizing a cool audio editing tool from Wondershare (works on both Windows&Mac)

1. Mix MP3s from the Command line

By utilizing this method, only one line of code is needed to join multiple mp3 files:
copy /b *filename1.mp3 c:\joinedfile.mp3.
The “*filename1.mp3” part defines the source directory of your files. Replacing “filename1.mp3” with the right url path of your files. This will combine all mp3 files in the file alphanumerically. If you only want to join files starting with a letter a, simply add an “a” before “*”, so that’s a*filename1.mp3.
c:\joinedfilename.mp3 defines the target directory for joined files. You can also replace it with any filename you want here.

Though this would take longer time to get your files merged, it is always an available free way for you to try. Be sure to save a copy of the original files so that you won't lose anything if you are not satisfied with the combined files.
