## What it is
IoTSound (formerly balenaSound) is a deployable application that turns a Raspberry Pi into an audio streamer for existing speakers, supporting Bluetooth, AirPlay 2, Spotify Connect, and UPnP with synchronized multi-room playback. It is deployed via balenaCloud and supports multiple DACs for improved audio quality.

## Use cases
- turn old speakers into an airplay receiver
- build a multi-room audio system with raspberry pi
- add spotify connect to a hifi
- stream bluetooth audio to dumb speakers
- synchronized audio playback across rooms
- diy alternative to sonos
- set up a raspberry pi music streamer

## When to choose
- you want a one-click deployable multi-room audio streamer on Raspberry Pi
- you need Bluetooth, AirPlay 2, and Spotify Connect in one device
- you already use balenaCloud for device management
- you want to revive old speakers with open-source software

## When to avoid
- you need a guaranteed long-term maintained project - maintainers are being sought and alternatives are recommended
- you want a polished audiophile player with local library management (consider moOde, Volumio, or piCorePlayer)
- you don't have a Raspberry Pi or balena-compatible setup
