## What it is
Ableton Link is a C++ header-only library that synchronizes musical beat, tempo, and phase across multiple applications and devices over a local network. It enables peer discovery and session participation so apps can start, stop, and change tempo together in real time.

## Use cases
- synchronize tempo and beat between multiple music apps
- sync a DAW with a DJ application over local network
- keep multiple devices playing in musical phase together
- integrate Ableton Link support into my audio app
- let apps join and leave a shared musical session without disruption

## When to choose
- you need tempo/beat/phase sync between music applications on a LAN
- you want a header-only C++ library with CMake integration
- you're building a DAW, DJ tool, or live performance app that interoperates with Ableton Live

## When to avoid
- you need sample-accurate audio streaming rather than tempo/phase sync
- your apps communicate over the internet rather than a local network
- you need a permissively licensed library for a closed-source product without negotiating the proprietary license

## Facets
- artifact type: library
- maturity: active
- function: concurrency, networking, sdk
- domain: cross-platform, developer-tools
