Shield
A steady 3D pink-noise shield that masks speech and softens sudden sounds. Doesn't move or change, so it fades into the background and stays comfortable for long sessions.
Generated on the fly by the same engine that powers the app.
dpli validates every preset against a neural mass model — a mathematical simulation of how populations of neurons respond to acoustic input. Only the patterns that drive sustained, distraction-resistant states make it into the app. This isn't guesswork. It's computational neuroscience.
Read the science →Your brain detects looping audio in minutes. Once it finds the pattern, your focus breaks. dpli has no file, no loop, no pattern to find.
Read the science →Every sound is computed on your device's processor. dpli is built with privacy-by-design — ideal for classified, legal, or confidential work environments.
