Stitch any number of tracks together with crossfades between each pair. Build mixtapes and continuous sets.

About this DJ mix builder

Drop in N tracks in the order you want them to play, set a global crossfade length, and the tool stitches them together with smooth equal-power crossfades between each pair. The result is a single mixtape file.

Useful for DJ podcasts, workout playlists, sleep mixes, road-trip soundtracks and any case where you want continuous music without DJ software.

DJ mix builder FAQ

Will the BPMs match automatically?

No — crossfades are time-based, not beatmatched. For a continuous beatmatched mix, run each track through the Speed Changer to align BPMs first.

How many tracks can I add?

No fixed cap. Available memory limits how many can be processed at once — 10-20 tracks is comfortable on most machines.

Will the audio quality drop?

Output is a 192k MP3. For lossless mixtapes, ask and we can add a FLAC-output variant.

Are tracks rendered in the order I dropped them?

Yes — first dropped first, last dropped last. Use the up/down buttons next to each track to re-order before rendering.
