@audio-ui/core

@audio-ui/core

The logic of audio/ui's primitives with no UI framework in it: values on a grid, linear and logarithmic scales, range geometry, live sources a view can follow outside its render cycle, and frame scheduling.

@audio-ui/react is built on it. Use it directly to build the same controls for another framework, or for the DOM alone.

npm install @audio-ui/core

It has no dependencies.

Layout

Two kinds of module are published, each as its own subpath, and the folders tell them apart:

• primitives/<name>/: the logic of a UI primitive (a knob, a timeline, a piano roll): its controller, geometry and value handling. Imported as @audio-ui/core/<name>.
• audio/<name>/: audio and music logic with no interface in it: analysis (spectrum, waveform peaks, filter and compressor curves, levels), device (an effect or an instrument as named parameters: state, ranges, steps, scales), pitch (notes, frequencies, pitch detection), midi (messages, files, the Web MIDI input) and time (tempo, bars and beats, ticks and seconds, the grid, the look-ahead scheduler). Imported as @audio-ui/core/<name>.

What both build on:

• value/: scales, ranges, formatting, change and commit event details, live sources and stores
• dom/: frame scheduling, pointer release, visibility, data attributes
• shared/: language helpers, math, pitch names

index.ts is the public API of what the primitives share. @audio-ui/core/internal holds helpers for adapters and may change in any release.
