Free Audio Joiner - Merge Audio Files Online
Arrange compatible audio files, trim each clip, adjust volume, and apply fades. Preview your sequence, then export one merged WAV directly in your browser.
Merge Audio Files Online for Free
Use Vamriko Audio Joiner to combine multiple audio files into one track. Add your recordings, arrange clips in the order you want, preview the sequence, and export the finished audio as a WAV file directly in your browser.
Combine voice recordings, podcast segments, interviews, lessons, or music clips. File compatibility depends on your browser's ability to decode each recording.
How to Join Audio Files
Add your files
Select multiple audio recordings or drop them into the file area. Wait for the files to decode before reviewing or exporting the project.
Arrange and edit
Reorder clips using drag and drop or the move buttons. Select a track to trim its start and end, adjust volume, or apply fade-in and fade-out settings.
Preview the sequence
Listen to the assembled audio and review the clip order and transitions. Pause playback before making further changes, then preview the updated sequence.
Render and download WAV
Click Render WAV and wait for processing to finish. Download the merged file and listen to it before using it in another project.
Edit Audio Before Merging
Adjust individual clips so the final sequence follows your preferred order. Use the trim controls to exclude unwanted beginnings or endings, and lower the volume of louder recordings when needed.
Fade-in and fade-out settings soften a clip's beginning or ending. Keep a copy of your original files and check the downloaded result, especially when combining recordings made at different levels.
Export Your Combined Audio as WAV
The current Audio Joiner creates a 16-bit PCM WAV file. MP3 and M4A export are not available in this version, even when you add MP3 or M4A recordings.
The renderer determines the output sample rate and channel count automatically from the decoded tracks. The WAV file size depends on the duration, sample rate, and number of channels.
WAV provides an uncompressed output for compatible editing and production applications. Joining recordings does not restore quality already lost in the original files.
Audio Processing and Privacy
Audio decoding, playback, and WAV rendering are implemented with browser audio APIs. The tool's processing functions read and combine your selected files locally rather than uploading them for processing.
The page also loads third-party services such as analytics and advertising scripts. Local audio processing does not mean the entire page makes no network connections; review the site's privacy information for those services.
Keep the browser tab open while the project renders. Processing requirements depend on the recordings, project duration, and available device resources.
Audio Joiner FAQ
Can I merge multiple audio files online?
Yes. Add multiple files that your browser can decode, arrange their order, and export them together as one WAV file.
Is Vamriko Audio Joiner free?
Yes. You can use the browser-based Audio Joiner to arrange compatible recordings and create a downloadable WAV file for free.
Can I merge MP3 files?
You can merge MP3 files when your browser can decode them. The current export format is WAV rather than MP3.
Can I combine different audio formats?
Yes, if the browser can decode each file. Compatibility depends on the format, codec, and browser, not only the filename extension.
Can I reorder the audio clips?
Yes. Drag tracks in the track list or use the move-up and move-down buttons to change their sequence.
Can I trim audio before joining it?
Yes. Select a track and adjust its Trim start and Trim end controls. The editor also provides volume, fade-in, and fade-out settings.
Can I download the merged audio?
Yes. Render WAV creates the combined file, and Download WAV saves the result to your device.
Does joining audio improve its quality?
No. The tool assembles decoded recordings and exports WAV; it does not restore detail lost in low-quality or previously compressed source recordings.
Are my recordings uploaded for processing?
The tool's file-reading and audio-rendering functions process the recordings locally in the browser. The page separately loads analytics and advertising services.
Why will an audio file not load?
The browser may not support its codec, or the file may be damaged. If decoding fails, try another compatible recording and review the message shown by the tool.
