When you combine audio files, you combine them so that multiple files exist as one audio file. You can use both online audio joining sites and offline audio joining programs.
You can combine two or more songs if you are making a playlist and want them to play one after the other without pauses. It is common for some YouTube albums where the creator uploads all songs combined into one video.
Another reason to combine audio files is if you have recorded voice memos or voiceover, but there are many mmm and other unnecessary parts. You can delete these sections and then combine other clips into one continuous file.
Several ways to combine MP3 and other audio files are detailed below. You can choose whichever method you think is best for your situation.
Tip: If your audio files must be in a different format to work with any of these websites or programs below, or if you want the exported file to exist in some other audio file format, there are free ways to convert audio to a different format

Cut & Mix Sound With Bold

Here’s a quick rundown of how to use Audacity to trim and merge audio files:
- Use the File> Open menu to import the audio file you want to trim.
- Once loaded, click and drag anywhere in the song to highlight what you want to delete, and then press the Delete key.
- Feel free to zoom in as close as you need to to find the exact parts you want to cut.
- Repeat steps one and two to edit another audio file that you want to combine with this one.
- Select the entire second one, copy it, and then return to the first window the one you edited.
- Go to the beginning or end (where you want to place another audio file) and use the Edit> Paste menu item to place the copied clip next to the other.

Use Windows Command Prompt to merge files
This shouldn’t be your first option if you don’t like to mess with the command line, but it’s still handy that you can do it without downloading any software or opening a site to join a song.
One of the drawbacks of this file merging method is that you have to enter the name of each song on the command line, or at least rename the songs so that it is easier to type.
- Open a command prompt.
- Change the directory where your audio files are located. Here’s an example:
cd C: Users Matt Downloads
Enter this command, where each filename corresponds to the files you are dealing with:
copy / b file.mp3 + file2.mp3 + file3.mp3 + otherfile.mp3 finalmerge.mp3
Note that in our example we are merging four songs. The most recent part, named finalmerge.mp3 , is the name we chose as the new file. All other instances are the names of the files we are merging.
Tips for merging audio files
If you need to use audio from a video, you can extract audio from it quite easily. Just make sure you don’t violate copyright by doing this.
Most songs have a bit of silence at the very end. If you want your merged songs to play seamlessly, remove those spaces in Audacity or the other audio editors mentioned above. Just play the song as many times as you like to make sure there are no unwanted quiet spaces before exporting audio.
By the way, if you want to have areas of silence between your songs but don’t have them yet, Audacity is a great way to do it. Use the New> Silent menu item anywhere in the recording to add blank spaces of any length you choose.
