AURA — Audio Unified Rust Architecture

CLAP-first plugin framework for LX Audiolabs. Runtime + formats + build + CLI. Built on Slint + baseview.

Crates	aura-*
Umbrella	aura → use aura::*
CLI	cargo aura ...
Config	aura.toml
License	GPL-3.0-or-later

Scope

AURA is intentionally narrow:

Committed to	Not shipping
UI: Slint + baseview only (FemtoVG/Skia/software backends)	egui, iced, Vizia
Formats: CLAP, VST3, LV2	AU, AAX, VST2
Hosts: Bitwig-first, REAPER, others	Pro Tools / Logic-only
Platforms: Windows, Linux, macOS	iOS / embedded

CLAP is primary. VST3 and LV2 are supported but not an excuse to grow a kitchen-sink framework.

Design principles

1. Slint + baseview only — renderer is a backend choice, toolkit is not
2. Thin formats — one PluginLogic API, three wrappers (CLAP, VST3, LV2)
3. Framework layout — crates/ · examples/ · tools/
4. One CLI: cargo aura — new, add, build, install, doctor, preview, add-ui
5. Built-in IPC: aura-shm — cross-plugin shared memory (publishers, consumers, spectrum, band energy)
6. KISS for humans and agents — aura.toml, boring paths; orientation in agal
