The widener
you can see.
Most wideners are a knob and a promise — turn it up, hope it holds together in mono. DeltaWidth shows the width you’re making, band by band, and draws what it costs when the mix folds to mono. Build believable stereo from a narrow source, and keep it mono-safe unless you decide otherwise.
Every widener sounds huge — until it hits a mono system.
Stereo tricks are cheap and mono is unforgiving. The wide mix that filled the room turns thin, hollow or gone on a phone, a club sub, a Bluetooth speaker — and most tools give you no way to see it coming.
DeltaWidth is built on one truthful promise: no free width. Decorrelation always trades mono-compatibility for space — so instead of hiding that, DeltaWidth draws the cost and hands you the meter. You widen with your eyes open.
Two stages. Make width, then shape it.
Stage one stays deliberately octave-stepped — the coarse bands are exactly why generated width sounds solid instead of smeared. Stage two is where you get surgical: a resolution switch (post-v1) opens ⅓-octave and finer for mixing and mastering. Finer is not always better, and DeltaWidth says so.
See the width, and what it costs — per band.
Hit MONO and the wings collapse — the plot paints in red exactly what’s lost per band. Not a guess, not a promise: a measurement. That truthfulness is the product, and it’s the same thesis behind every Delta tool — see what it does, measure the cost.
Width, not a room — and that’s deliberate.
DeltaWidth makes something sound like it was recorded wide — the same direct sound reaching two microphones slightly differently, the way an ORTF or spaced pair captures a real performance. That’s width, and it holds no room.
Rooms, early reflections and reverb tails are a different tool’s job. Keeping them out is what lets DeltaWidth stay clean and mono-safe. A future PHASE ↔ CAPTURE blend will move from a surgical phase rotation to a modeled mic-pair for extra realism — still no room at either end.
Another living tile on the wall.
Like every Delta plugin, DeltaWidth reports to DeltaWall — so its width and mono-risk show up on the session wall next to your spectra, EQ ghosts and compressors. See at a glance which tracks are super-wide and fighting in mono, and narrow the offender from mission control.
Every DeltaWidth license includes DeltaWall.
A free standalone app that shows every Delta plugin in your project on one wall — one live tile each, no routing or setup — so you can watch the whole session from one window.
In development.
DeltaWidth is the fourth Delta product, in active development after DeltaMeter, DeltaEQ and DeltaComp reach the market. The engine already generates and measures width with a null-tested transparent core; the gorgeous UI, the PHASE↔CAPTURE convolution and the fine-resolution mode are on the way.
