My Favourite App For Joining MP3 Files


I've recently been recording some audio onto my PC, and the finished result occupied 10 separate MP3 files.  Having separate files for each track or song can often be a good idea, of course, if you might want to listen to each one separately.  But in some cases, it's useful to be able to merge separate MP3 files into one, to simplify your listening and the storage of the file.  And so it was in this case.  Which meant that I needed to find some Windows software that could do the job.

After trying a couple of programs I eventually opted for MP3 Album Maker, from MakeItOne.  It's a tiny download of less than half a megabyte, is malware-free according to VirusTotal and Web of Trust, and did the job perfectly.  Just fire up the software, choose the MP3 tracks you want to merge, and the program does the rest.  You end up with a single track that you can simply play all the way through without having to repeatedly load up different files into your player.

And it's free too.  So head to and see what you think.

I've been using iwisoft video converter for this. Don't let the name fool you. Works great on audio files too.

Good tip. I already had it installed for converting video. Just make sure to select the MP3 profile and check the Settings before you start.

Or you can just use copy /b command in a CMD prompt:
copy /b "part1.mp3+part2.mp3+part3.mp3" "combined.mp3"
This can give a lot of problems with playback, converting and etc. It sounds like this is the way the above program works.

An old favorite of mine is Merge MP3 from:

This removes the header of each file prior to mergeing, and have never given me any problems.

Yes, I second the use of Merge MP3. Good, simple. does the job.

I was interested in this, so I did a little more digging on the MakeItOne website. Here's what I found.

The app was first released in 2004, and had been updated periodically since. It requires .NET 1.1. (Maybe a later version of .NET would also work... I don't know if all of the different .NET versions are backward-compatible.)

The joining process is reversible. You can get your original separate files back from the joined file if you want to.

If you experience a problem with "hiccups" or clicks between the pieces of a joined file, the author recommends removing your MP3 tags prior to joining the tracks. Apparently, some users have had this problem.

I wanted to find out how this app works in this regard: Does it un-encode and then re-encode the mp3 files (which would create some generational loss of fidelity), or does it join the files without altering the fidelity of each track? I think the answer is the latter, but I never found that to be explicitly stated on the web site.

Wow, good work, Gil.
