This is how you can combine audio files

  1. Combine Audio Files With the Command Prompt
  2. Merge MP3s Together With MP3 Merger
  3. Merge Music Files With Audio Joiner
  4. Combine Audio Files With Audacity

Do you have lots of separate music files saved in a Windows 10 folder? If so, it would be better to merge some of those files together so that you can play through multiple music tracks included within a single file.

Then you won’t need to manually select to play each song file separately within your media player. This is how you can merge your favorite music into a single file in Windows 10.

4 solutions to combine audio files on PC

Method 1: Combine Audio Files With the Command Prompt

  • You can utilize the Command Prompt to combine separate audio files. To merge music with the Prompt, right-click the Start button to open the Win + X menu.
  • Select Command Prompt (Admin) to open the window shown below.

  • Open the folder that includes the MP3 files you need to merge in the Command Prompt. You can do that by entering cd in the Prompt followed by the folder path.

  • Enter this command in the Prompt: copy /b audio file1.mp3 + audio file2.mp3 audio file3.mp3. Of course, you’ll need to change the file names there to match your actual audio files.
  • Then press the Enter key. That will combine the two MP3s in the copy /b command into one new output file.

Method 2: Merge MP3s Together With MP3 Merger

MP3 Merger is freeware software that merges one, or more, MP3 files. It is a straightforward utility for merging sound files together that also enables users to edit track data and set up CUE sheets for MP3s. You can combine music files together with MP3 Merger as follows.

  • Click Download Now on this webpage to save MP3 Merger to a folder.
  • Then you can open MP3 Merger from the folder you saved it to.

  • Click Add Files to open the Select files to merge window shown directly below.

  • Then select two, or more, files to join by holding the Ctrl key; and press the Open button.
  • You can adjust the default directory for the output file by clicking the button beside the Output filename text box.
  • To set up a CUE sheet for the output file, click Settings and select the Create CUE sheet for the output file option

  • Then click the Merge files button.
  • A Warning dialog box then opens. Press the Yes button on that dialog box window to confirm.

  • After you’ve merged the files together, close MP3 Joiner and open a media player.
  • Select to play the new output file that includes the two MP3s you merged together.

If your audio files aren’t MP3s, your best bet is to convert them to that format and then merge them together with MP3 Merger. You can convert numerous audio files to MP3s at this webpage. Press the Choose files button there to select source files, and then click Start conversion to convert them. Alternatively, check out the audio conversion software in this post.

Method 3: Merge Music Files With Audio Joiner

Alternatively, you can merge music with the Audio Joiner web app. That app merges MP3, M4A and WAV files together. This is how you can combine sound files with Audio Joiner.

  • Open the Audio Joiner web app in your browser.
  • Click the Add tracks button to select the music files to merge. The web app then displays the selected tracks as in the snapshot directly below.

  • You can adjust the playback order of the tracks by clicking the up or down arrows.
  • The blue sliders on the tracks configures the playback interval when one tracks stops and the other starts playing. That enables you to cut out some of a song if you drag the blue slider away from the far right of a tack.
  • Audio Joiner also includes Crossfade and Fade-out transition effect buttons on the right of tracks. You can click those buttons to toggle their effects off or on.

  • Click the Join button to merge the selected tracks together. Note that it does take a while for the app to merge the files together.
  • Click Download to save the output audio file to a folder.

Method 4: Combine Audio Files With Audacity

Audacity is among the best sound editor software for Windows 10. You can also merge separate audio files with Audacity by overlapping two alternative music tracks. Follow the steps below to combine music tracks with that software.

  • Click Download Audacity on this webpage, select Audacity for Windows and click Audacity 2.3.0 Installer to save the software’s setup wizard to a folder. Then you can add the software to Windows with the installer.
  • Open the Audacity software window.
  • Open the first audio file by clicking File > Open.
  • Click Import Audio on the Project menu to open the second audio file in Audacity. Now you should see two waveforms for the selected audio files in Audacity.
  • Press the Time Shift Tool button (with double arrows on it) to open the Time Shift Tool.
  • Next, place the Time Shift Tool cursor at the beginning (far left) of the second audio track you want the file to play.
  • Click and drag the Time Shift Tool cursor to the right until it gets to the end of the first track’s waveform. Thus, the second track’s waveform should start where the first track’s waveform finishes.
  • Click File and select Export as WAV to export the merged music file.

So you can combine audio files with the Command Prompt, Audacity, MP3 Merger software and Audio Joiner web app.

Merge MP3, MP3 Toolkit and Free MP3 Cutter Joiner are three other software tools you can join sound files with. By merging audio files, you can bring your music collection together.
