beamer-core

Format-agnostic core abstractions for building audio plugins with Beamer.

This crate provides the shared traits and types used by all plugin formats (AU, VST3):

• Plugin traits: Descriptor, Processor, HasParameters, Parameters
• Audio buffers: Buffer<S>, AuxiliaryBuffers<S> with real-time safety guarantees
• MIDI types: Complete MIDI event handling including MPE and Note Expression
• Parameter types: FloatParameter, IntParameter, BoolParameter, EnumParameter with smoothing
• Transport info: DAW tempo, time signature, and position data

Usage

Most users should use the beamer crate instead, which re-exports everything from beamer-core along with the format-specific integration layers.

Use beamer-core directly only if you're:

• Building a plugin format adapter (e.g., for CLAP or AAX)
• Creating a custom plugin framework on top of Beamer's abstractions

Advanced: Manual Parameters Implementation

Most plugins should use #[derive(Parameters)]. However, the Parameters trait can be implemented manually for advanced scenarios like dynamic parameter counts, custom storage strategies, or shared parameter pools across plugin instances.
