How it works

Three steps. No DAW.

No chopping, no counting bars, no spending an hour on every track.

Upload a track

MP3, WAV or M4A, straight from your phone or computer, up to 10 minutes. It detects the BPM, key and beat grid.

Mark the section

Drag the start and end. The markers snap to the downbeat and to 8-bar phrases, so the mix comes out clean.

Get your Extended Mix

A 16- or 32-bar intro and outro built from the song's stems. Download an MP3 with the BPM and cue points inside.

Features

Built for DJs

Everything a track needs to come in and out of your set the right way.

124.0BPM

BPM and key

Automatic tempo and key detection, including the Camelot code (like 8A), so you know right away what it mixes with.

BAR 1BAR 9
✓ 8 BARS

8-bar phrase snapping

The markers snap to bars, and a live counter shows how many bars you've selected. One tap rounds it to a multiple of 8.

VOCALS

Extended from the stems

The track is split into drums, bass, music and vocals. The intro and outro are built from the drums, bass and music, with no vocals, at the same loudness as the song.

FAQ

Frequently asked questions

Is it really free?+

Yes. During the beta everything is free, with no credit card needed. And if a version doesn't sit right, tell us what to change and you'll get a second version free. Re-uploading a track you've already done doesn't count again.

What exactly is an Extended Mix?+

A longer version of the track with a clean, rhythmic intro and outro, so it's easy to mix in and out of your set without the vocal landing in the middle of the blend.

Does it change the song itself?+

No. The part you picked stays exactly as it is. The intro and outro are built from the song's own drums, bass and music, with no vocals, locked to the beat and at the same loudness.

What files can I upload?+

MP3, WAV, M4A and more, up to 10 minutes and 80 MB per track. Full sets and long live recordings aren't supported yet.

How long does it take?+

A typical track takes a few minutes from upload to finished mix. When several people upload at once, tracks join a queue and are processed one after another.

What happens to my tracks?+

Files are deleted from the server automatically within 12 hours. No library, no sharing. Only upload music you have the rights to use.

Does it work on my phone?+

Yes, it was built phone-first. You can also install it as an app straight from your browser.

Found a bug / have an idea?+

Great, that's what the beta is for. Send us a WhatsApp message and we'd love to hear it.
