How to Combine Audio Files in Windows 10/11 and Mac: MP3, WAV, M4A and More

By Cecilia Hwung | Last Update:

There are many situations when you want to learn how to combine audio files into one. The how-to tutorial is one part, and the accompanying settings and considerations for various scenarios will largely influence which audio merger tool to use. For instance, here are some of the situations or concerns in between:

  • Merging hundreds of MP3 files/audio files: it would be time-consuming to import and arrange them one after another in video or audio editing software – imagining dragging the clips on the timeline repeatedly.
  • You have audiobooks, but the player cannot play the chapters in the correct order. The solution is to combine audio files orderly or edit their ID3 tags, both can be done with method 1 below.
  • One is mono, the other is stereo audio, or differs in bit rate, sample rate, and codec. In these cases, you can convert them to stereo and parameter settings, and merge audio files into one. In method 1, you can use one tool to complete all the tasks in one go.

With the right tool at hand, you can follow the detailed steps below to merge mp3 files, join WAV lossless, as well as lots of other audio formats from songs, digital audio books, recordings, and more.

No matter it is for combining audiobooks, voice recordings and songs, you can batch import the files into VideoProc Converter AI, with option to adjust their order easily and visually.

Additionally, you can trim, enhance or edit the metadata of these audio files while merging them into one. See how easy it is with detailed steps below.

Note: The Windows version now supports AI-powered Super Resolution, Frame Interpolation, and Stabilization to enhance video and image quality. These AI features are not yet available in the Mac version but will be coming soon.

After you've got VideoProc Converter AI installed on your Windows or Mac computers, fire it up on your Windows desktop, then follow 3 simple steps below:

Step 1: Import multiple audio files into this audio joiner software.

After downloading and installing VideoProc Converter AI, you can click the Video module from main interface, and drag and drop audio files.

Step 2: Manage audio file settings if needed.

You can click the arrow icon on each file to change their order when merging into one file. The top most audio file will be the beginning of the merged audio.

  • To change mono to stereo: Click the gear-shape icon to go inside the codec settings, and change it from the drop down menu in audio channel settings.
  • To change audio cover art: Also inside the gear-icon code settings, click the Name & Tag tab, and change album cover here. You can also change metadata such as title (song name), artist, album, genre, or add comments.

If you want your media player to correctly play a series of audio files, such as all the chapters of audiobooks, besides merging them into one, you can also manage their metadata to get well-organized.

Step 3: Merge audio files into one.

Choose a target format, such as MP3, tick Merge, and click Run to start joining all the audio files in the queue into one track.

2. How to Combine Audio Files in Audacity

Audacity is an open source and cross-platform audio editor. The latest version 2.4.1 can be run on Windows 10/11. It supports for WAV (*.wav), AIFF (*.aiff), MP3 (*.mp3), and OGG (*.ogg) audio files. The tool made to combine audio files is called Time Shift Tool, which can be tuned for multi-tracks. By pressing the Time Shift Tool, you can drag the waveform of the clip forward or backward until it satisfies your ears.

Step 1. Download the latest version of Audacity on your Windows 10/11 computer.

Step 2. Launch & import audio in Audacity: File > Import, pick up audio files from the local file folder.

Notice: There are audio formats unable to be input in Audacity, and you can do nothing with that but to click on OK. Have some audio files other than MP3? You can combine different formatted audio files.

Step 3. Click on Time Shift Tool (with the double-headed arrow), or you can press the keyboard hotkey F5 > drag the Time Shift Tool cursor to the position where you want your second clip to be played after the end of the first clip.

Step 4. Export the audio file: File > Export > choose Export as WAV in the drop-down list.

Things Worth to Note
  • If you want each clip be played in full track, you may drag the cursor of one clip either to the beginning or the end of the other clip. A yellow line will appear when you reach the head or the bottom of the waveform, which is to help you locate the position in a trouble-free manner.
  • If you use the Time Shift Tool to put one audio track within the waveform of the other track, then it'll be another story: two soundtracks will be played at the same time. By adjusting the volume of one track, there will be a mixing effect after the export.
  • The bad news is, however, you are not allowed to listen to the audio files you just combined in Audacity before exporting.

3. How to Merge MP3 Files on Windows 10 with VLC

VLC is an open-source free program that you can free access to. Based on its introduction of how to merge videos, we have tested its capability of combining audio files, and it turns out to be feasible as well. Before we kick off, you need to make sure that all of your audio files have the file extension of .mp3. Otherwise, this method may not work for you. (Notice: if you have different formatted audio files such as .flac and .mp3, see the workaround.)

Step 1. Download and install VLC on your computer.

You are recommended to install VLC locally by its default route.

Step 2. Use the keyboard shortcuts Win+X > click Command Prompt in the pop-up list. Or, you can use the hotkey combination Win+R to open Run > type cmd in the box > hit Enter, then the Command Prompt will be opened as well.

Run Command Prompt
[Win+R] > cmd to run Command Prompt

Step 3. In the Command Prompt, enter the command: cd c:\mp3, then hit the Enter key.

Sidenote: The c:\mp3 command is the file folder directory where your mp3 audio files are kept. If your audio files are kept in C disk, but not with a file folder, you need to enter c:\

Step 4: There will be c:\mp3> command already exists, copy and paste commands as follows:

"C:\PROGRAMFILES\VideoLAN\VLC\vlc.exe" -vv 1.mp3 2.mp3 --sout-keep --sout=#gather:transcode{acodec=mp3,ab=128}:standard{access=file,mux=dummy,dst=combinedout.mp3}


1. The C:\PROGRAMFILES\VideoLAN\VLC\vlc.exe command refers to the directory path where the VLC launching program is located in your Windows computer, which is also the default path of VLC setup. Change it if you've set a different destination path for your VLC installation.

2. The 1.mp3 2.mp3 command refers to the filename of your audio tracks. Customize the part based on your personal demands.

3. The combinedout.mp3 command refers to the file name of the combined file. You can change it to the one you like.

All commands to combine VLC audio files with Command Prompt

As you can tell, to combine audio tracks in VLC is a manual-process intensive and back-breaking work. You need to make sure that each command is flawlessly followed by one another. Otherwise, one step wrong, you need to start from scratch. If you are not familiar with computer codes, chances are that you have trouble in going through all those commands successfully. Another thing worth mentioning, it may not be friendly to users who need to combine dozens of audio files saved in different names at one time. You may have to manually enter the command for each audio file, and one code wrong, the failure is doomed.
