When you’re in need of audio merger software to combine your favorite audio files, you’ll want some of the best ones to make it happen. Believe it or not, they’re a lot easier to come by than one might think and all of the examples listed below are free to use at one’s leisure.

Whether you’re looking to cut, merge or split, many of the examples below can do all and some can only merge. You can find a solution below based on your needs.

Merge Audio with Command Prompt

Yes, that Command Prompt, the one you can find if you have a Windows PC. Believe it or not, but there’s a command line that you can punch into Command Prompt that can literally merge audio files together.

What’s so great about it? For starters, you can use it anytime–provided you have a Windows PC–and you don’t have to pay a single penny to make use of it. If you’re looking for one more reason to fiddle with the Command Prompt, then you can find the instructions below. However, if you aren’t comfortable using the Command Prompt, skip this option. It can be very intimidating for people that aren’t familiar with it or don’t use it often.

With that being said, here’s what you do to merge audio files with the Command Prompt:

1. Start by opening your Windows Startup menu, which you can find in the bottom left corner of the screen, provided you never moved it. However, you can also open the Windows Startup menu by tapping the Windows key on your keyboard, as long as you have one on your keyboard to press.

2. In the Windows Startup menu, type into the menu “Command Prompt” and click on it when it shows up in the search results of your Windows Startup menu.

When the Command Prompt starts, you’ll want to first open the directory that contains your audio files. Considering your audio files may be placed in a folder that can potentially be different from others, the images below are used as a placeholder. If your audio files aren’t placed in your (C:) drive, then you need to change it accordingly.

cd C:\Users\USERNAME\Music

3. In the Command Prompt, type this command, however, change the folders and drive if they’re different for you: “cd C:\Users\USERNAME\Music

copy /b audio1.mp3 + audio2.mp3 newfile.mp3

4. Now, to merge a few files, you need to know the names of the audio files you want to merge and use this command to merge them, like so: “copy /b audio1.mp3 + audio2.mp3 newfile.mp3

The above command will merge “audio1.mp3” and “audio2.mp3” into a new audio file called “newfile.mp3.” And there’s virtually no limit to how many audio files you can merge this way, provided you have the room and time for it.

Merge Audio with Audacity

Merge Audio with Audacity

By far one of the most well known pieces of software to merge audio files with is none other than Audacity. It’s often times one of the first programs that anyone with any interest in audio mixing goes to. Why? Because it’s free and has many of the generalized tools that you’ll find in many different audio mergers.

Not only is Audacity user friendly, but you can cut, merge and split audio files over and over again as many times as you want. On top of the great audio tools, you have Audacity’s library of filters and effects to fiddle with while you’re merging audio files, including options for recording audio of your own.

The final start that Audacity gets is its open source nature. You can install a bunch of different plugins that can enhance Audacity’s capabilities, options that aren’t native, but are made native through the use of said plugins.

One of the downsides to Audacity, however, is that it doesn’t come with an entire suite of editing tools; it comes with many of the common features you’ll see on any retail audio mixer. On the bright side is, of course, its plugins. They can certainly soften the blow and expand Audacity’s abilities, but if you don’t like using plugins, that could be a strike against you.

Merge Audio with MP3 Toolkit

Merge Audio with MP3 Toolkit

MP3 Toolkit takes a slightly different approach to audio merging needs by breaking apart their different functions. Take any piece of audio software and examine it. Did you realize that all of their tools are just out in the open? Right, and that can sometimes be user unfriendly. MP3 Toolkit makes it easier on any user by breaking its functions apart into neat little sections, like in the image above.

You have tools such as:

  • MP3 Converter: an audio file converter that can make use of command extensions like MP3 (obviously), WMA, WAV, OGG, AAC and many more. If you have a video file that’s MP4, FLV or AVI–to name a few–you can even rip the audio from it.
  • CD to MP3 Ripper: is essentially CD burner software. Since CDs play their audio formats as .cda, you can’t copy the files and play them from your PC. With the CD to MP3 Ripper, you can pull the files from the CD and convert them into an audio format you can play.
  • MP3 Merger: Contrary to its name, it can do more than merge MP3 files.
  • MP3 Cutter: Again, it does exactly what it advertises, but on more than MP3 files.
  • MP3 Recorder: If you have a microphone, you can use the MP3 Recorder to record said audio directly from the microphone.
  • It’s free: not a tool, but a worthy bullet point.

Merge Audio with MP3Cut

Merge Audio with MP3Cut

This one is an anomaly. Generally speaking, you cut and merge audio with a piece of software. MP3cut.net does things differently by allowing you to do what you would do with software and perform the same actions on their website.

For example, they have an Audio Cutter, an Audio Joiner and Audio Converter (and a few other apps) that can serve you in combining audio files. You simply upload the files to their platform and join the audio files in the way you want them. And it won’t cost you a penny.

On top of that, MP3Cut has a library of free foles, sound effects and background music, to name a few, to mess around with. Not a bad deal at all. There’s a number of different editing tools you can use, too.

Merge Audio with MP3Split

Merge Audio with MP3Split

Sometimes a friend throws you an audio file of an entire album and you’re stuck with this long running file that doesn’t have pause whatsoever. What can you do? Use MP3Split. Its primary function is to split audio, but its GTK version can split and combine audio files.

If you download MP3Split, make sure you download MP3Split-GTK. That’s the version that can merge audio files together.

Merge Audio with mp3DirectCut

Merge Audio with mp3DirectCut

Let’s put this out there right now: mp3DirectCut doesn’t do a whole lot. It can cut, split and merge audio files and that’s just about it. However, the gold lies with its ability to keep your audio files from decompresses, preserving the quality of your audio.

Merge Audio with MixPad

Merge Audio with MixPad

For a piece of software that’s as extensive as Audacity and provides professional recording and mixing, you’ll want to take advantage of MixPad. It’s free to use and its tools have the possibility to rival that of Audacity. While you’re merging audio files, try out MixPad’s editing tools.
