How To Merge MP3 Files Into One Long MP3
Merge MP3 is a free (no need to install) utility that is simple to use and does the job quickly. It doesn’t have all the complicated features of some commercial programs but, for the average user, this makes it much easier to use – even without configuring any options it works well.
Merge MP3 Features
- Merge as many files as you like – no limitations by size, length, or number.
- Sort files to be merged by filename (with or without directory), date/time or size.
- Optionally write ID3v1 and ID3v2 tags into the merged MP3 file.
- Optionally write VBR frame into the merged file – useful when merging files with different bitrates.
- Optionally convert the merged mp3 file into an audiobook format (.m4b) for iPod/iPhone.
- View detailed information about MP3 files to be merged, including MPEG header information and ID3v1 and ID3v2 information.
- Choose to use ID3 tag from any of the files to be merged to write into the target file.
- No complicated installation – intuitive interface and fast merge speed.
How To Use MP3 Merge – Download the program in a zip file from the developer here. Extract the zip file and run the MergeMP3.exe program – in our examples, we will use the commands from the File menu but you can also use the equivalent icons on the toolbar.
Choose to ‘Add Files’ (individual MP3s) or ‘Add Directory Recursively’ (add all MP3 files from a folder) from the File menu:
Tip: you can also just drag and drop MP3 files into the program window.
Files will be merged in the order displayed – use the up or down arrows in the toolbar to move tracks up or down the list if you want to change this order. Initially, the fields for Track, Title etc are greyed out – if you want to add them, tick the checkbox near the top left then fill in the details as shown above.
Select ‘Merge’ from the File menu and choose the save location (and filename if you didn’t fill in the fields in the last step) of the merged MP3 to start the merge process:
The merge process is very quick – merging a 13 track album only took about 5 seconds in my tests. Once complete, the merged MP3 is available in the location you specified.
Convert Into Audiobook Format (.m4b) for iPod/iPhone – The supplied program iTunesCoder.exe performs the conversion but you must have iTunes installed for the conversion to work. To convert into .m4b format, select View \ Preferences from the menu to open the Preferences window and select the Audiobooks tab:
Tick the box to ‘Automatically create audiobook…’ and browse/locate the iTunesCoder.exe program (it is in the same directory as the MP3 Merge program) then press OK. Now follow the normal merge process – remember to deselect the Audiobooks choice afterwards if you want to perform additional standard MP3 merges.
Notes – I have tested Merge MP3 with many albums and had no issues except for one particular album where the merging process froze (no progress in the progress window). Clicking Cancel brought up an error “thread error access is denied: error 5” which usually indicates a permissions issue.
The only way to close the program was by closing the MergeMP3.exe process in Task Manager. I checked the problematic album for file permissions and mp3 info/tags etc but have not been able to find any cause – perhaps there was something weird about the encoding. I have contacted the developer to see if he has any suggestions and will update if he does.
However, most users have no problems with it and as it worked fine on 99% of everything I threw at it I’m happy to recommend – the error was most likely due to an unusual mp3 format issue.
Merge MP3 is a simple but effective portable utility to merge MP3 files into one – the program menus and options are also very intuitive. It merges MP3 files without recoding so it is quick and there is no loss of audio quality – it basically just joins them together.
It doesn’t offer the most complex features but that also means no need for lots of tuition and audio tech knowledge – for the average user who wants to quickly merge MP3 files it seems ideal.
