## What it is
Steinberg's official SDK for developing VST 3 audio plug-ins, including the API, helper classes, AAX/AU wrappers, and example plug-ins. It enables building audio processing components that run inside host applications like DAWs.

## Use cases
- develop vst3 audio plugins
- build audio effects for daws
- create virtual instruments
- wrap vst3 plugins as au or aax
- learn vst3 plugin development with examples

## When to choose
- you want to build VST 3 audio plug-ins or virtual instruments
- you need cross-platform audio plugin support (Windows, macOS, Linux, iOS)
- you need AU/AAX wrappers for DAW compatibility

## When to avoid
- you need a runtime audio engine rather than a plugin SDK
- you target formats other than VST3/AU/AAX
- you want a higher-level framework like JUCE

## Facets
- artifact type: library
- maturity: active
- function: audio-processing, sdk, plugin-system
- domain: developer-tools, cross-platform
- platform: windows, cpp
- tags: vst3, audio-plugins, dsp, steinberg, cmake, audio, macos, linux, ios
