What’s new

Important: levels and band counts changed for accuracy.
• Readings are now correct under every window — most read slightly lower. Please recapture pink-noise calibration profiles.
• Band sets now follow ISO/ANSI exactly: 30→31, 60→61, 120→122 bands.
• Ads no longer interrupt a running measurement.
• A/C weighting no longer affects what is recorded — snapshots, calibration and Room Paint keep the true response.
• More reliable capture on busy devices.
