Common mistakes
- Trying to merge with only one file loaded and not understanding why the button is disabled.You need at least 2 files to merge. Add another audio file before continuing.
- Merging files with a different number of channels (one mono, one stereo) expecting a result with no adjustments.The tool uses the first file's channel count as the reference; if another file has fewer channels, it reuses its single available channel for the missing ones to avoid unexpected silence.
- Not checking the file order before merging them.Files are combined exactly in the order shown in the list. Use the up and down arrows to adjust the order before pressing 'Merge audio'.
Frequently asked questions
No. The entire decoding, merging, and re-encoding process happens entirely in your browser. The audio never leaves your device.
No. Files are concatenated directly one after another, with no silence gaps or transition effects (fades) between them.
Yes. Each file is decoded independently before merging, so you can combine files of different formats as long as your browser can decode each one.
There's no fixed limit on the number of files, but merging many long files increases processing time and the result's size, since everything happens in your browser's memory.
Alternatives
Editors like Audacity let you merge audio tracks by dragging them onto a timeline, with more control over transitions and overlaps. This tool is handy for a quick, sequential merge without installing additional software.
