How to Merge Multiple Audio Files Into One for Free (With Optional Crossfade)
How to join several audio files into a single track for free in your browser, with an optional crossfade so the join doesn't sound like an abrupt cut.
Joining audio files sounds trivial until the seam between them is audible — a hard cut between two tracks, or two takes of a voice recording, can sound jarring even when each file is clean on its own. A crossfade at the join point is what fixes that.

When crossfade actually matters
A hard cut is fine when both files already start and end on silence — two separate voice memos with clean gaps, for example. It's noticeable when a file ends mid-sound (music that hasn't faded out, a voice mid-word) — that's when a short crossfade at the join point makes the seam disappear instead of popping.
Joining video clips instead of audio files?
This tool works on standalone audio. If you're combining video clips, use Join instead — same idea, built for video files.
