merge music filesWe at MakeUseOf are determined to provide as much breadth in topics as possible so all of our readers’ interests can be addressed. We have explained a handful of ways to easily join and split videos, PDFs (on a Mac even), spreadsheets and other files. If you follow our Sound Sunday feature where our Answers editor lists free and legal MP3s, or just simply own an MP3 player, chances are you might be interested in how to merge music files and/or split audio files as well.

There has been an article on what to use to split and merge audio tracks, but it was more geared for the Windows user. This list will feature a few more programs that Mac and Linux users can use as well.

So whether you’re interested in removing the silent parts of an audio file, splitting audiobooks into more digestable parts, or you want to merge music files to create a long, no-skip playlist-like music file, the five time-saving tools we’ll feature up next might just help you achieve this task quickly.

Use The Command Line To Join MP3s

Using the simple code below, you’ll be able to join .mp3 files quickly and without additional programs.


cd C:\folder\with\mp3\files 

(press Enter)

copy /b file1.mp3 + file2.mp3 newfile.mp3

The new file will be created in the same folder (in this case,


) where the original file1 and file 2 are, unless you specify another directory. You could also use all the mp3s (using

) in one specific folder that you have switched to using the


(i.e. change directory) command:

 copy /b *.mp3 newfile.mp3

merge music files

You can replace


with something like


to include only files that start with the letter m. You’ll notice that this method is incredibly fast but it loads the original audio data so the ID3 tags will be all over the place (e.g. the new file may list the artist data from file1, but different album information from file2).

For a workaround, download the open source Mp3Wrap (available for Windows and Linux) and Mp3Splt (which we discuss later in this article) which serve to join and separate files respectively, while retaining ID3 information.

Mac and Linux users can use the following in the Terminal:

cat file1.mp3 file2.mp3 > newfile.mp3

Available as a portable application, Mp3splt is an open source and cross-platform command line (but we’ll use the GUI version) utility that offers advanced features. Once you download the Mp3splt-gtk version that comes with a GUI, you’ll be able to set splitpoints at specific time frames, split the original file into equal parts, extract the original tracks from an entire MP3Wrap-joined album track, and even play the file to visualize areas to trim.

Use The Simple MP3-Trimming Tool, MP3Cut (Web-Based)

Trimming a single mp3 file couldn’t be easier with Mp3cut. Just upload your file, select the portion of the song you want to save, hit the Download button and off you go!

The site comes with an eye-catching mp3 player and sliders across it so you can quickly choose an interval within the file to trim, which is useful if you don’t know the exact splitpoints.

DIY: Split & Join MP3 Files To Your Liking With Windows Movie Maker

merge music files

With Windows Movie Maker, you can import common audio files (such as .mp3, .wav, .wma), drag them to the timeline and use the Split/Trim functions. To join files, just place them right after the other in the Audio/Music timeline. Whatever’s left on this timeline will be saved as a new .wma file after you hit Publish Movie.

If you don’t mind the .wma file extension, you’re all set; otherwise, use an mp3 converter, such as MediaConverter or another great alternative. This method doesn’t restrict you in number of files you can join, and the timeline makes it very easy to use.

If you don’t want this two-step process that involves converting to mp3, and aren’t too keen on downloading too many applications, try Aviary’s Myna, which is a web-based audio editor.
