FASTEST CONTROLLED PATH
STUDIO PAIR
Vocals / InstrumentalFor clean production review, performance isolation, remix preparation, and karaoke workflows.
LOCAL-FIRST AUDIO INFRASTRUCTURE / WINDOWS FIRST
STEMVAULT separates audio without treating the original like disposable fuel. Every job carries its source, rights statement, model, settings, outputs, hashes, state, and recovery path.
PUBLIC SHOWROOMThe protected engine, uploads, jobs, and delivery records remain private on the production workstation.
01 / OPERATING POSITION
Real separation work begins before inference and continues after export. The source must be authorized, immutable, inspectable, recoverable, and connected to every result.
STEMVAULT turns that discipline into one operating room: intake, model selection, queue control, progress, validation, audition, manifests, and handoff.
02 / CHAIN OF CUSTODY
Validate file type, signature, size, ownership statement, and source hash before the queue sees it.
Choose a separation objective, output format, model adapter, and compute path deliberately.
Run one controlled job with visible phase, progress, interruption state, and cancellation.
Reject empty output, hash every stem, preserve the manifest, and expose evidence before delivery.
Compare outputs in the same workspace without disconnecting them from their production record.
Deliver a recoverable project package instead of a folder full of anonymous audio files.
03 / SEPARATION MODES
FASTEST CONTROLLED PATH
For clean production review, performance isolation, remix preparation, and karaoke workflows.
CORE SESSION PATH
For arrangement, mix diagnosis, reconstruction, and detailed creative work.
DEEPEST ARRANGEMENT PATH
For precise rebuilding when the recording and the model support meaningful detail.
MULTI-PASS PRODUCTION PATH
Retains the full drum bus, then separates kick, snare, toms, hi-hat, ride, and crash with a dedicated second model.
Model separation always contains uncertainty. STEMVAULT records the method and exposes the outputs for listening; it never labels model inference as a perfect studio multitrack.
04 / PROTECTED FOUNDATION
Uploads, jobs, logs, results, manifests, and controls live behind server-side session checks.
State writes use temporary files and atomic replacement. Interrupted work is identified instead of pretending to be complete.
Every asset and output path is resolved inside its intended storage boundary.
Every intake requires an explicit authorization statement before audio enters the system.
Significant actions append to a durable record with actor, timestamp, action, and identifiers.
The interface, records, and governance survive when models or compute backends change.
05 / THE HONEST BOUNDARY
CURRENT ENGINE TRUTH CPU execution is validated. CUDA acceleration on the current GTX 1080 remains unverified. Four-stem catalog support remains staged, and owner listening on a commercial-length song is still a separate artistic review—not a reason to misstate the working system.
