How it works

From a folder of tracks to a finished mix

No manual editing, no waveform-dragging. WeaveShift scores every possible handoff and renders the best one.

Upload your tracks

Drop in WAV or MP3 files, in any order. Mix formats freely as long as sample rate and channels match.

Pick a vibe

Choose a built-in profile — EDM, vocal trance, lounge, jazz, cinematic, heartbreak — or tune your own.

WeaveShift analyzes every handoff

Beat & onset evidence, key/BPM compatibility, energy and loudness curves, plus vocal-safety scoring.

Get your continuous mix

Download one WAV or MP3, plus a transition-by-transition report explaining every decision.

Features

Built for repeatable, explainable mixes

Everything a manual DJ edit gets right, without the manual part.

Profile-driven engine

Built-in profiles tuned for EDM, vocal trance, lounge, jazz, cinematic, and heartbreak sets — or write your own.

Vocal-safe transitions

Optional neural vocal separation keeps blends from clashing two vocal lines together.

Beat & key aware

Every candidate transition is scored on beat/onset evidence, key & BPM compatibility, energy, and loudness.

Full setlists, not just pairs

Stitch any number of tracks into one continuous mix — not just two-track transition tests.

Explainable results

Every mix ships with a detailed report of why each transition was chosen — no black box.

Your format, your export

Export as WAV or MP3, at original timing and pitch — ready to share or upload anywhere.

FAQ

Questions, answered

What happens when my trial ends?

You automatically move to the Free tier. Nothing is deleted and no mix is taken away — you just keep the stable, generous free allowance going forward unless you choose to subscribe.

Do I need to install anything?

No. WeaveShift runs entirely in your browser — upload your tracks, pick a profile, and download the finished mix.

What audio formats are supported?

WAV and MP3 in, WAV or MP3 out. You can mix formats within one setlist as long as sample rate and channel count match.

What's the difference between heuristic and neural vocal safety?

Heuristic scoring is fast and available on every plan. Neural vocal separation (Demucs) is slower but more precise about isolating vocals, so it's reserved for your trial, Pro, and Studio.

What's the difference between Pro and Studio?

Pro is built for one creator or one channel: full setlist mixing and Demucs, with saved profiles coming soon. Studio adds higher monthly minutes, and — coming soon — priority rendering, more concurrent jobs, and team workflows and shared workspaces for heavier or multi-channel production.

Can I cancel Pro or Studio anytime?

Yes. Monthly billing has no lock-in; annual billing is prepaid for the year at the discounted rate. Either way, if you cancel you keep full Free-tier access — you're never locked out of your account.
