About this tool
Combine any number of tracks into a single file. Drag them into order, trim each one, and choose what happens where they meet — a crossfade of any length, a gap of silence, or a straight join. Everything is previewed before you export.
FAQ
Can the tracks blend into each other?
Yes. Every junction has its own crossfade control with a choice of curve. Equal-power keeps the loudness steady through the overlap, which is what you want for music; linear is the simpler straight fade.
Do the files have to be the same format?
No. Anything your browser can decode can be mixed with anything else — different formats, sample rates and channel counts are all matched up automatically before they are joined.
