Join MP3 Files Together with Merge MP3

Mark O'Neill 21-12-2008

merge mp3 files together Whenever I buy a CD, I immediately burn a backup copy onto my computer so I can listen to it on my iPod and on WinAmp while I am working on the computer. But if it is a comedy concert or music concert, one of the things that annoys me is how the end of each “chapter” of the CD can cause a break in the audio. If the comedian or singer / band is in full flow, I don’t like how the “atmosphere” of the concert is suddenly broken because it is the end of track 2 or track 3.


So Merge MP3 helps by allowing me to join all MP3 files together into one big MP3 file. This means that they can all play one after another without a break. I don’t have to think about whether the track is about to end or not. I can just hit “play” and enjoy the music / comedy.

The only slight snag with this app is that you can hear a very slight “jump” where the audio files connected with one another. The merging isn’t totally seamless. But this is a very minor thing as far as I’m concerned. Audio quality fanatics on the other hand will have high blood pressure problems and go totally off their heads.

What I particularly like about Merge MP3 is that it is a portable app, no installation required. So just download the app, transfer it to your thumb drive and you can merge mp3 files together on any Windows PC.

When you double-click on the .exe file, it opens up the interface:

join mp3 files together


Then either navigate to the MP3 files you want to merge, or (even easier), drag and drop the MP3 files onto the Merge MP3 app :

merge mp3 - freeware to join mp3 files

After choosing a target folder, a name for your newly merged file and completing the new ID3 tag, the app gets to work joining all the files together one by one. In my case, it took less than 5 seconds.

Now I have one big file, instead of 14 little ones! So another advantage is that it tidies up your computer folders!

Do you use another free app to merge MP3 files?

    I use Joyoshare Video Joiner. That's a lossless video/audio merging tool.

    Perfect! I needed to merge two mp3 files - parts 1 & 2 of an interview - and this did it seamlessly.

    Thanks for recommending this app.

      That's probably because it's a Windows program.:-)

    I eagerly downloaded this app but it doesn't work. Just freezes every time I click on start converting. If I press cancel I get the message Thread Error Access is denied(5).

    I have tried it twice and have to shut down my laptop both times as this program doesn't work, won't cancel and won't close.

    Any ideas...?

    I tried joining two mp3 files from a cd using the dos cmd above and the file that was created was only about 200k instead of 5MG.
    Any ideas what happened?

      You did it directly from the CD?

      Try putting the MP3 files onto your computer (or a USB drive) then do it. See what happens then. It might not have liked the CD disk.

    I use Easy CD-DA Extractor when ripping, as there is an option to merge all files ripped (during a session) into one large file. Supports all popular audio file formats such as 3G2, 3GP, MP1, MP2, MP3, Windows Media Audio (WMA), Ogg Vorbis (OGG), MP4, M4A (iPod AAC and Apple Lossless), AAC, aacPlus (AAC+ and eAAC+), FLAC, Musepack (MPC), WavPack (WV), WAV, AIFF, Monkey's Audio (APE), CUE and M3U. (and no,I don't work for them)

    Use MediaJoin at your own risk. I had to re-install it on XP Pro multiple times, and each time, it quit working after 1 to 2 days. When it *does* work, it's awesome, but it may be hit or miss for each user.

      Don't know why MediaJoin has been problematic for Aaron. I've not had a moment's bother with it and it's certainly had a caning on my computer.

    I use MediaJoin. Seems to have gone missing from the developer's site, Mystic Media,
    but is around on:
    and other sites on a Google search.
    Very rarely gives any sort of glitch at all and I have used it to make comedy programmes continuous for PC/mp3 player use without the slightest hint of a join. The originals were burnt audio CD's made on a Pioneer hi-fi stand-alone recorder which was set to insert a track marker automatically every three minutes (seamless, as far as the sound is concerned), so, just like a commercial spoken-word CD, it makes it easier to pick up from the same point again, if interrupted. As you say, a PC infuriatingly treats them all as separate tracks and I've found MediaJoin to be superb in what it does in stitching them back together again for use with whatever player you have. It will also output in mp3 and other formats, saving the aggravation of converting.

    Total Commander (if you have!) merges the files (need not be MP3 alone) on the go - excellent.

    DOS command (copy /b file1.ext+file2.ext newfile.ext) will also do the same (as given in the earlier comments) and one can automate by incorporating in to a batch file.

    That dos command makes us to combine MP3 files into a single one manually,do automatically preferring Mp3merge is good option.

    Wow...incredible. I was just thinking how nice it would be to find an app like this for all the DJ Mixset CD's I have that I've ripped and then tracked out, but want to re-join to copy to my Sansa for the gym. Big ups!

    Mark is correct, quality is untouched.

    Does this app transcode the files?
    I'd love to do this but not if it lowers the quality of my music tracks.

    • Mark O'Neill

      It doesn't touch the quality of the music tracks in any way. All it does is join the files together, nothing more.

      If you're still a bit apprehensive and want to test it, just make copies of your MP3's and test the app on the copies. If you're not satisfied in the end, then delete the MP3 copies. Then you've lost nothing.

    I've been using this one for a couple weeks after a couple other free MP3 merger's left me wanting more. I've had zero problems with Merge MP3, and it works incredibly fast.

    Could you just tell Itunes and winamp that that album is a gapless album,? it should therefore play and cue the next track to play without a space between.

    You can use an old DOS command like:

    copy /b 1.mp3 + 2.mp3 3.mp3

    I've used Audacity in the past to do the same thing, but this looks like a slick alternative.
