When to Choose SATlive
SATlive is purpose-built for live sound system alignment. Its Windows-native architecture with ASIO support provides rock-solid low-latency performance with professional audio interfaces. If you already run a Windows laptop at FOH with an ASIO-compatible interface and your work is focused purely on PA alignment and phase optimization, SATlive delivers a refined workflow for that specific task.
When to Choose SonaVyx
SonaVyx is ideal when you need more than just transfer function measurement. Browser-based access means no software installation and no OS restrictions. The AI diagnostic engine analyzes your measurement data and provides specific recommendations. Guided workflows walk through the entire PA tuning process step by step. If you also need STI measurement for speech systems, noise dose monitoring for OSHA compliance, or professional client reports, SonaVyx covers all of these from a single platform.
