Regroove
A recorded set is one flat stereo file. Regroove opens it back up — track by track, tempo by tempo — and repairs what needs repairing without disturbing what doesn’t.
The whole set. The recorded master is displayed at the top, and every original track is placed beneath it, on one shared timeline. Markers are displayed where Regroove found a potential imperfection in the mix. 
The Remixer. Each mix can be rebuilt from the tracks that composed it, with gain and the EQ bands shaped to match your original mix.
Align
Find every track inside the mix.
Regroove locates each original track within the finished set, works out how fast it was played and whether its pitch moved with the tempo, and lays the source underneath the master on a shared musical timeline. Sets drift, ramp, and change key; the timeline follows them rather than assuming one fixed BPM. Every placement carries a confidence figure you can see — and correct by hand when the room got the better of the algorithm.
Review
Evidence, not opinions.
Regroove reads the finished mix for the things that actually go wrong in a set — a transition that lands hard, one track sitting on top of another, beats pulling apart — and lists them with timecodes you can jump straight to. Nothing is changed for you. Plenty of what it flags will have been deliberate, and dismissing a patch is a normal outcome.
Repair
Fix the handover, not the whole mix.
Open a rough patch and the Remixer rebuilds just that passage from the source tracks beneath it. Balance one record against another across the overlap, shape it separately through low, mid, and high, choose a gradual or abrupt fade, and snap the moves to the bar. Everything outside the region you opened is left exactly as you played it.
Preserve
Your recording stays your recording.
Regroove never writes to your files. Placements, tempo corrections, and treatments are project data held alongside the audio, reversible at any point, and rendered only when you export. The recorded master is the base of every export, so the performance you actually played survives intact between the parts you chose to repair.
It all runs on your own Mac. Regroove contains no networking code, so your sets and your record collection never leave the machine.
Status
In development — arriving soon.
Regroove is being built and tested now at Atelier Advani in New York, on real recorded sets. Questions, or interest in testing a pre-release build? Write to raj@atelieradvani.com, or see the support page.
