Nelipa Tools is an independent laboratory of precision instruments for audio post-production — built by a working re-recording mixer, for the professionals who carry a film through its final mix. We turn the daily chaos of sound delivery into legible, repeatable systems.
Not a suite. Not a platform. Five small, exact instruments — each built to remove one specific point of friction from a real session, and nothing more.
Analyses the files, applies a declarative naming formula, builds a fractal folder structure and distributes everything into it — one button, the entire package. The folder constructor has no real equivalent on the market: cross-product distribution, combination pruning, asymmetric branches, and a live colour-keyed preview that links every rule to the folders it produces.
Batch stem rendering for Pro Tools. Files = tracks × intervals: ten tracks across twenty intervals become two hundred files in one run. Speaks to Pro Tools through the official PTSL SDK over gRPC — offline bounce, configurable bit depth and sample rate, every plug-in resolved on the way out.
Carries timecoded notes out of online review platforms and text files into the Pro Tools session itself. Assembles an AAF of empty regions whose names hold the note text, each pinned to its frame. A standard Import → Session Data brings every comment onto a dedicated track — beside the picture, not in a browser tab.
Matches stills to audio takes by capture time, then writes the chosen image into the audio file's own metadata. On-set photographs travel with their recordings from then on, readable by any application that respects the standard. The archive answers questions the file list alone never could.
Batch replacement of an audio track inside a video container without re-encoding the video stream. Subtitles, chapters and every other track stay intact; only the sound is swapped. If the new audio doesn't fit the container, the audio alone is transcoded. Drop in a video and a WAV — seconds later a clean file appears. Name builder, presets, task queue.
Precision is a form of respect. We build order, and give the hours back to the work that deserves them.
Every instrument grows from one conviction: mechanical work has no place in a creative room. Removing it well — without new rituals to learn — is its own discipline.
Imperative scripts age badly — they encode one studio's habits and forget the rest. These tools are declarative: describe what the delivery should be, and the same rule holds for any project that comes through the door.
Anyone can pile on complexity. A clear, predictable result — reached by removing everything that doesn't serve it — takes years on the floor. That reduction, learned through Lean practice and real deliveries, is the whole point.
Only the work a machine can do should be automated. The judgement, the taste, the years behind a decision — those stay with the people. The time saved goes back into the conversation and the craft.
I'm a working film sound designer. I build the instruments I needed to finish my own mixes — and good enough to hand to the people I work beside.
Not a startup — a workshop. Run by someone still on the dub stage every week, building the small, sharp tools the work demands, and quietly putting them in the hands of other professionals. The method comes from years on real productions, and before that, from a factory floor where Lean discipline was the difference between order and chaos.
It's a small shop, so the message reaches the person building the tools. Bring a session, a problem, or a delivery you've been dreading — we'll find out together whether one of these instruments fits.
