01
Bring your track
Upload one 44.1 kHz stereo pre master (WAV recommended), or up to 60 original stem files, and choose the result you want.
02
Let the checks run
A stereo pre master is separated by our separation engines, verified and mastered automatically, with no review step. Original stems are organised into 6, 8 or 12 groups and checked, then you listen to them in your workspace.
03
Download your result
Stereo: download one mastered stereo (24-bit/44.1 kHz). Original stems: download the groups you approve, plus a mastered stereo if you added it at checkout (+£24.99).
Original stems: listen before you approve.
For original-stem projects, your upload remains the reference, approved stem groups stay downloadable, and an added mastered stereo begins only after the groups pass their checks and are approved. Stereo masters are released only after automatic production checks.
Stem-aware mastering
Mastered with the stems in mind.
Every stereo pre master is separated by our separation engines, verified and mastered, bringing the final track’s tone, dynamics, level and playback together in one 24-bit/44.1 kHz master. For original stems, add a mastered stereo at checkout for +£24.99 while your approved groups stay protected in the same project.

StemMasterPro™
For a reliable production handoff
Choose this when you want a checked, automatically mastered stereo, or organised original stems with listening approval and private delivery.
One-click separation
For quick experiments
Useful when broad isolation is enough for a demo, rough edit or creative test.
Engineer + DAW
For fully bespoke direction
The strongest route when you need conversation, manual intervention, revisions or restoration.
Separation quality depends on what is present in the supplied audio. No system can recreate information that is not there, and engineer-led outcomes depend on the source, brief, time and practitioner.
