SonaVyx: Free Browser-Based Alignment
SonaVyx provides transfer function measurement with H1 coherence-weighted estimation, delay finding via impulse response peak detection, and phase display. The AI diagnostic engine analyzes measurements and provides specific adjustment recommendations. Running in any browser means you can use your phone as a walk-around analyzer during system check. The free tier includes all measurement capabilities with no artificial limits on accuracy or resolution. For live sound engineers who need quick system checks without carrying a laptop, SonaVyx fills a gap no other tool addresses.
Smaart v9: The Industry Standard
Rational Acoustics Smaart v9 is the most widely used system alignment tool in professional live sound. Its multi-input capability, sub-sample delay resolution, and extensive trace management make it indispensable for complex system tuning. The $899 perpetual license covers both Windows and Mac. Smaart excels at large-scale system alignment where multiple measurement points are compared simultaneously. It lacks AI analysis but provides the manual tools experts need.
SATlive: System and Room
SATlive bridges system alignment and room acoustics correction with up to 8 simultaneous inputs and automatic EQ suggestion. At €490, it sits between SonaVyx (free) and Smaart ($899). Strong in European markets with integrated room correction features that go beyond pure alignment into treatment suggestion territory.
Waves TRACT: Array Optimization
TRACT is specifically designed for line array optimization within the Waves SoundGrid ecosystem. It predicts coverage patterns and calculates optimal array angles rather than measuring transfer functions. Complementary to measurement tools rather than a direct replacement. Best for system designers who need predictive array modeling.
