Free Audio Merger Online — Combine MP3 WAV and AAC Files
Combine multiple audio files into one seamless track. Reorder clips by drag & drop, choose output format and download. Up to 10 files per merge. No software, no account.
How audio merging works
Files are joined end-to-end in the order you specify — creating one continuous audio track without any gap or click between segments. The output uses the format and bitrate of the first file by default, or you can select a custom output format. For files with different sample rates (e.g. 44.1 kHz and 48 kHz), the tool automatically resamples to a consistent rate to avoid speed-up or slow-down artifacts at the join point.
Practical use cases for audio merging
Podcast production: join intro music, main interview segments and outro music into one publishable episode. Audiobook assembly: combine individually recorded chapters into complete chapters or a full book file. Music production: merge stem files or combine multiple recorded takes into a single track for mixing. Voice-over work: join individually recorded sentences or paragraphs into a continuous narration. Sound design: sequence multiple sound effects into a composite audio clip for games or video.
FAQ
How many files can I merge at once?
Up to 10 audio files in one merge operation.
Can I merge files of different formats (e.g. MP3 and WAV together)?
Yes. Files of different formats are automatically converted to a consistent format during merging. Select your desired output format before merging.
Will there be an audible click or gap between merged tracks?
No. The files are joined seamlessly without any audible gap or click. For smooth crossfades between tracks, add a short silence clip between them.
Can I reorder the files before merging?
Yes. Drag and drop the file cards to arrange them in any order before clicking Merge.
What is the maximum total file size?
Up to 200 MB total across all merged files.
Does the output file retain the metadata (artist, album, title) of the first file?
The output retains basic format metadata. For detailed metadata editing, use an audio tag editor after merging.
