Real-Time Routing & Sync
Click active sources on the left to change input routing protocols, or click speaker zones on the right to toggle room sync states.
Engineered for Hi-Fi Performance
SnapDog runs on Raspberry Pi hardware to drive dedicated audio DAC HATs, synchronizing high-fidelity audio streams across your home network with open integrations.
Multi-Room Synchronized Audio
Leverages the Snapcast protocol to distribute low-latency PCM streams to client nodes over standard Wi-Fi or Ethernet. Network drift is kept under 2ms for seamless synchronization.
Parametric Equalizer
Calibrate acoustics per zone using multi-band parametric EQ curves. Tune speakers to your room boundaries or load correction profiles from Spinorama database measurements.
Smart Home Integration
Publishes zone states and controls automatically to Home Assistant. Uses MQTT autodiscovery to expose clients as media players without custom configuration.
KNX Integration Modes
Supports both Group Address listening and native Device Mode. In Device Mode, you can import the snapdog.knxprod product database into ETS to configure the server directly.
Smart Buffer Caching
Dynamic client buffering prevents dropouts caused by Wi-Fi disruptions or local network latency spikes. Configurable pre-cache sizes ensure stable, continuous playback.
Real-time Embedded OS
A custom, read-only Linux kernel system built for Raspberry Pi. Mounts in RAM to prevent SD card corruption, boots in under 4 seconds, and prioritizes low-jitter audio execution.
Zero-Configuration Provisioning
Configure new client nodes via a local setup hotspot. Once booted, SnapDog OS spins up a captive portal to configure your home Wi-Fi credentials and select your DAC hardware.
Join the SnapDog Hotspot
Flash SnapDog OS onto a microSD card and boot your Raspberry Pi. The client will automatically publish a local Wi-Fi hotspot named SnapDog-XXXX. Search for it on your smartphone or computer and connect.
