## What is Echorooms?

Repeatability Desk groups baseline and follow-up readings with room, position and equipment context. Compare medians and observed spread while keeping exclusions and missing band fits visible.

HOW TO USE THE UPGRADE
1. Capture repeated readings with consistent placement and conditions, or inspect clearly labeled examples. Open Desk and identify the session.
2. Add baseline and follow-up readings. Include at least three readings per group for summaries; record a reason for each exclusion.
3. Review medians and observed ranges, save the session and export the CSV with every included and excluded reading.

Room capture, saved reading history, detail views, comparison and acoustic planning references remain. Missing band data is no longer filled with synthetic values in measurement reports.

WHAT TO KNOW
Three to 12 included readings per group for summaries; up to 50 sessions. Band medians need at least three actual band fits. Observed spread is not a confidence interval or proof that treatment caused a change. Device microphones, placement and ambient conditions affect results. Simulator and example readings are labeled and are not acoustic measurements. Envelope contrast is estimated from the capture, not a calibrated independent noise floor or ISO compliance check.

iPhone and iPad. No account required.
