Independent Pitch

Shift pitch in semitones or cents while tempo stays exactly where you set it.

Audio quality detection

Spot low-bitrate and transcoded files before they ruin your set.

Track rename

Clean up messy filenames and tags in seconds, right from your library.

Waveform display

A crisp, responsive waveform view that makes cueing and beatmatching effortless.

Tempo & Pitch

Speed and key, fully independent.

Push the tempo without your vocals turning into chipmunks. elian decouples BPM and pitch so you can adjust each one separately, with studio-grade time-stretching that stays clean at any setting.

Harmonic Mixing

Know every key, instantly.

elian detects the musical key of every track and maps it to the Camelot wheel, so you can find harmonically compatible tracks at a glance and build sets that flow.

Audio Quality

Know your files before you play them.

A built-in analyzer flags low-bitrate files, upscaled MP3s, and other quality issues before they make it into your set — so every track sounds as good as it should.

Track Organisation

Your library. Perfectly labelled.

Clean up messy filenames and tags directly inside your library. No more digging through Finder or third-party taggers to get your collection in order.
