## What it is
HISE is an open source cross-platform framework and application for building sample-based virtual instruments and audio effects. It lets developers design instruments with samplers, synths, and effects, then export them as VST/AU/AAX plugins or standalone apps for Windows, macOS, Linux, and iOS.

## Use cases
- build a sample library player plugin
- create virtual instruments from sampled audio
- export VST AU AAX audio plugins
- develop hybrid synth-sampler instruments
- make a standalone music app for iOS
- stream large sample libraries with low memory usage

## When to choose
- you want to build sample-based virtual instruments and export them as native audio plugins
- you need disk streaming and a custom lossless codec for large sample libraries
- you want a WYSIWYG UI editor plus scripting and C++ extensibility in one tool

## When to avoid
- you only need simple audio effects without sampling
- you want a lightweight library to embed in an existing codebase rather than a full IDE-like framework
- you need a fully permissive license - the license is custom and not standard open source

## Facets
- artifact type: framework
