Merge Audio
Join two or more audio files in input order. Mixed formats are supported because every input is re-encoded into one MP3, WAV, or M4A track.
About Merge Audio
Merge Audio joins two or more audio files — MP3, WAV, M4A — into one continuous track, in the order you drop them. It re-encodes through a proper concat pipeline, so mixed formats and sample rates come out as one clean file. Everything runs in your browser: voice memos and recordings never leave your device.

Frequently asked questions
What formats can I merge?
Any mix of common audio formats — MP3, WAV, M4A, OGG. Because the tool re-encodes into your chosen output format, the inputs don't need to match each other.
What order do the clips play in?
The order you add them. Re-drop the files in a different order to change the sequence.
Does merging lose quality?
The output is re-encoded (that's what makes mixed inputs work), so choose WAV for lossless output or MP3/M4A for smaller files at very good quality.
Are my recordings uploaded?
No. The audio engine runs entirely in your browser — it downloads once on first use, then works offline.
Can I trim the clips first?
Yes — run Trim Media on each clip, then merge the trimmed results.
