About this crossfade joiner
A crossfade is the simplest DJ trick: as track A fades out, track B fades in over the same period, so there's never a moment of silence between them. This tool takes two audio files, applies a clean equal-power crossfade with the duration you set, and writes a single combined output.
We don't analyse or index your files.

Crossfade FAQ
What's a good crossfade length?
For full-song transitions, 8–12 seconds usually feels musical. For spoken-word edits, 0.5–2 seconds is plenty. Above 20 seconds you start losing the second track's intro.
Will the audio quality drop?
It's re-encoded to MP3 at 192k. For maximum-quality DJ work, prefer FLAC inputs and ask us if you'd like a FLAC-output version of this tool.
Will the BPMs match automatically?
No — this is a straight crossfade, not a beatmatched DJ mix. For BPM matching, use the Speed Changer or Pitch Shifter on one track first to align tempos.
Can I crossfade more than two tracks?
Right now it does pairs. Run the result back through with a third track for a 3-track mix.
