How to Export Measurement Data for Client Reports

TL;DR

Professional measurement reports require raw data, not just screenshots. SonaVyx exports measurement data in four formats: CSV for spreadsheets, FRD for compatibility with REW and ARTA, WAV for impulse responses, and JSON for programmatic analysis. This guide covers what to export, which format to choose, and how to structure a client deliverable.

Export Formats Overview

Format	Best For	Opens In
CSV	SPL logs, RT60, STI, octave band data	Excel, Google Sheets, Numbers
FRD	Frequency response, transfer function	REW, ARTA, Smaart, VituixCAD
WAV	Impulse responses	Any DAW, REW, convolution plugins
JSON	Full session data, programmatic use	Custom tools, API integration

Step-by-Step Procedure

Complete your measurements. Run all required measurements before exporting. SonaVyx tracks measurement state in the session — switching modes does not lose previous data.
Open the Report Generator at /tools/report-generator. Select the session containing your measurements.
Choose your template. Quick Summary for a one-page overview, Client Summary for a visual presentation, or Technical Commissioning for a detailed engineering report. Free tier includes a watermark; Pro removes it.
Export individual datasets. For raw data delivery: go to each measurement mode, tap the export icon, and select the format. SPL logs export as CSV with timestamp, LAeq, LAFmax, LCpeak columns. Transfer function exports as FRD (frequency, magnitude, phase). Impulse responses export as 48 kHz / 24-bit WAV.
Export traces. Stored traces in the Traces panel can be exported individually. Right-click a trace and select CSV, FRD, or JSON. Each export includes metadata: date, device, calibration status, FFT size, and averaging count.
Build your report package. A professional deliverable typically includes: (1) executive summary with health score and key metrics, (2) frequency response plots with before/after if applicable, (3) RT60 per octave band table, (4) STI readings at each measurement position, (5) raw data files for the client's records.
Include the measurement certificate. SonaVyx generates a unique certificate ID with SHA-256 hash for audit trails. The certificate includes venue name, engineer name, date, health score, and a public verification URL.

What Each Report Template Contains

Quick Summary: Health score, top 3 issues, frequency response plot. One page. Suitable for email summaries.
Client Summary: Visual layout with health gauge, category scores, frequency response, RT60 chart, STI results, equipment list, and AI recommendations. 3-5 pages. Suitable for client presentations.
Technical Commissioning: Full engineering report with all measurement data, octave band tables, phase plots, coherence, impulse response, before/after comparisons, EQ settings, and compliance assessment. 10+ pages. Suitable for project handoff and regulatory submissions.

Common Mistakes

Exporting only screenshots. Screenshots lose data resolution and cannot be reanalyzed. Always provide raw data files alongside visual plots.
Forgetting calibration status. If you measured without calibration, note this in the report. "Approximate levels — phone microphone, uncalibrated" is honest and prevents misuse of the data.
Not including measurement conditions. Document: date/time, room conditions (occupied/empty), HVAC state, measurement positions, equipment used, and calibration reference.

Tool Bridge

Open the SonaVyx Report Generator to create client reports. Use trace exports from the measurement workspace for raw data deliverables.
