SonaVyx vs Smaart for Church Sound
Church Sound: What Actually Matters
Church sound systems face unique challenges: spoken word intelligibility in reverberant spaces, untrained volunteer operators, tight budgets, and inconsistent acoustic environments from sanctuaries to gymnasiums. The measurement tools you choose must address these specific needs rather than generic live sound requirements.
Feature Comparison for Worship

|---|---|---|
| Speech Intelligibility (STI) | Yes — full STIPA per IEC 60268-16 | No — requires separate tool |
| Reverberation Time (RT60) | Yes — ISO 3382 with room targets | No — IR only, manual calculation |
| AI Diagnostic for Volunteers | Yes — plain English recommendations | No — requires expert interpretation |
| System Alignment (TF) | Yes — H1 with coherence | Yes — H1/H2/H3, multi-input |
| Guided Workflows | Yes — step-by-step wizards | No — assumes expert knowledge |
| Budget | Free (Pro $29/mo) | $899 perpetual |
| Platform | Any phone or laptop browser | Windows or Mac laptop required |
| Training Required | Minimal (guided UI) | Significant (professional tool) |
| Treatment Recommendations | Yes — specific panel suggestions | No |
| Report Generation | Yes — shareable with leadership | No built-in reporting |
Why STI Matters for Churches
Speech intelligibility is the single most important measurement for worship spaces. A congregation that cannot understand the sermon is not served by a flat frequency response. SonaVyx includes STIPA measurement per IEC 60268-16, which directly quantifies how well speech is transmitted through the room and sound system. Smaart does not include STI measurement, requiring a separate investment in tools like NTi XL2 ($4,000+) or Bedrock AM.
The Budget Reality
Most churches operate on limited AV budgets managed by volunteer teams. Spending $899 on Smaart plus $200+ on measurement microphones and audio interfaces creates a significant barrier. SonaVyx runs free in a browser using the built-in microphone of any laptop or phone. While a calibrated measurement microphone improves accuracy, even an uncalibrated phone measurement with SonaVyx provides actionable diagnostic information that helps identify the biggest problems: excessive reverb, feedback-prone frequencies, and coverage gaps.
AI Diagnostics for Non-Experts
Smaart presents raw measurement data that requires training to interpret. A volunteer sound operator sees a transfer function plot and has no idea what to do next. SonaVyx AI diagnostics translate measurements into plain English: "The 250Hz region is 8dB elevated. This causes muddy vocals. Reduce the low-mid EQ on the main output by 6dB." This bridges the gap between measurement and action without requiring acoustics expertise.
When Smaart Is the Right Choice
Large churches with professional audio staff, multiple speaker zones, and complex DSP systems benefit from Smaart multi-input alignment. If you have a full-time sound engineer and a budget for professional tools, Smaart provides deeper system alignment capabilities. For the other 90% of churches running single-zone systems with volunteer operators, SonaVyx delivers more relevant features at zero cost.
Choose the Right Tool
- Choose SonaVyx if you have volunteer operators, limited budget, and need intelligibility measurement with guided workflows.
- Choose Smaart if you have professional staff, multi-zone systems, and budget for advanced alignment tools.
