Unlimiter

Gives back the attacks a limiter flattened. It tells an attack by how far a fast follower of the level rises over a slow one, and lifts it: adaptive, by what it is missing to reach the crest, so a healthy attack is left alone. It plays the de-limiter of audio.js. It is a device: a state, a panel, an engine and tools, each its own file.

Installation

Copy
pnpm dlx shadcn@latest add @audio-ui/unlimiter

Controls

Panel

The panel draws the lift an attack gets for its size, how far the fast follower is over the slow one, through the package's own curves, with the crest when it is adaptive.

Copy
import { UnlimiterPanel } from "@/components/audio-ui/devices/unlimiter/panel";
import { unlimiterDevice } from "@/components/audio-ui/devices/unlimiter/device";

const [state, setState] = useState(() => unlimiterDevice.defaults());

<UnlimiterPanel onValueChange={setState} value={state} />;

Engine

Create it, connect it and update it as for any device: see The engine.

The browser has no such node. The engine plays the processor of @audio/dynamics-unlimit's manifest as published, in an AudioWorklet fed only while it plays: off, or until the worklet is ready, the sound goes round it. Every value on the panel changes as it plays; its followers' times are the package's. It looks at no sound ahead, so it adds no latency.

Measured on a loop of hits pushed 12 dB into a limiter, which took their crest from 11.6 to 9.9 dB, the adaptive unlimiter gave it back to 11.7 dB. On the loop as it was, it added 0.9 dB.
