Getting started

Introduction to RAVET Getting started with RAVET Independent project starters RAVET architecture RAVET feature catalogue Small examples and use cases

Processing & events

Extended portable processing Parameters, state, bypass and metering Parameter attachments CLAP gain editor control bridge Control-thread data services Building an audio processor Sample-timed events and automation Audio-thread ownership and control handoff

DSP

Prepared signal processing Prepared processor routing graphs Stereo delay: controls, timing and feedback

Instruments & MIDI

Portable MIDI short messages CoreMIDI UMP endpoints Bounded OSC packets and explicit UDP MIDI sine CLAP reference Native sidechain CLAP reference Subtractive synth: voices, envelope and filter

State & files

Observable state, undo and presets Coherent control/audio snapshots Gain session state Explicit preset-file libraries WAV/AIFF streams and audio handoff buffers

Editors & graphics

Native embedded-editor prototype Portable layout, SVG drawing and animation Reusable local web controls Native UI messages, device settings and snapshots

Devices & plug-in formats

Standalone audio devices Explicit CLAP discovery and trusted loading REAPER host validation VST3 gain reference AudioUnit v2 gain reference AAX references LV2 gain reference
