Soniclyze 2.21 improves the multilingual experience and makes iCloud sync more reliable and easier to control. • Report language: choose from 17 languages instead of 5; Arabic reports now use a consistent right-to-left layout; report and interface translations have been revised in many languages, most extensively in Turkish, Hindi, and Arabic • iCloud Sync: new "Delete iCloud Data" option; "Auto-clean old recordings" now applies only to the device where it is set and no longer affects your other devices through sync; preference sync across devices is more reliable • A new "App Language" entry in Settings opens system settings, where you can choose a separate interface language for Soniclyze • Search recognizes keywords in more languages and ignores accent marks • Re-exported reports include the "Time History" chart again; re-exporting the same measurement in a different time zone keeps the same report number • Stability and experience improvements: direction icons mirror correctly in Arabic, notification titles follow the app language, and dates in reports use the report language's format

Soniclyze 2.2 introduces iCloud sync and brings systematic fixes to report language, standard selection, and error messages. • iCloud sync (Pro): measurement records, projects, saved measurements, and calibration history sync record by record into your own private iCloud database; location coordinates, place names, and the organization name, inspector name, and notes you enter are stored with end-to-end encryption. Turn it on in Settings → Data Management → iCloud Sync; off by default. If your subscription lapses, your data stays in iCloud and becomes available again when you resubscribe. • Report language fix: reports exported in non-Chinese locales no longer fall back to Chinese • Standard selection now follows your region; multi-point noise measurement adds six scenario types, automatic day/night determination, and custom standards • Reorganized Settings, with clearer entry points for account and data management • Corrected the sound-insulation rating (Rw/STC) reference data and the speech-intelligibility (STI) weighting calculation; results for both may differ from previous versions. For compliance use, re-export reports with this version • Stability and experience improvements: fully localized error messages, recordings now saved as 24-bit and can be turned off in Settings, plus fixes for several crashes and audio interruption handling

Soniclyze 2.1 fixes several playback issues and further refines translations across all supported languages. • Fixed a silent playback issue that could occur when returning to the file analysis playback screen • Fixed the signal generator continuing to play after leaving its screen, and playback being silently suppressed by background listening in certain scenarios • Translation refinements across all 17 languages • Other stability improvements

Soniclyze 2.0 brings the first macOS release, along with a month of feature work and fixes. • Now available on macOS: a native desktop experience supporting microphones, multi-channel audio interfaces, and other professional recording devices. • Input and output devices and channels are now selectable and shared across SPL, RTA, sound insulation, calibration, and play-and-record. Fixes issues where the channel was silently pinned, where switching devices required an app restart, and where recording continued with invalid data after a device disconnected. • Several measurement algorithm corrections: the octave filter bank now uses a true band-pass topology; corrections to the sound-insulation rating (Rw/STC) reference data, the speech-intelligibility (STI) weighting calculation, RT60 signal deconvolution and noise-tail truncation, spectral peak interpolation for total harmonic distortion, and the SPL Lmax figure, which now uses A-weighted LAFmax. • PDF report system upgrade: restructured SPL report sections, an automatic table of contents in every report, a report integrity hash and QR code on the final page, cumulative spectral decay (CSD) waterfall plots in reports, and extensive typography and terminology refinements across all 17 languages. • New report verification tool: scan a report's QR code from the Toolbox to verify the report's integrity (free). • Redesigned Settings: regrouped entries and a unified look across secondary pages, with the calibration, about, and subscription pages substantially reworked. • Uncalibrated status is now stated explicitly on measurement screens; the subscription page shows price and renewal terms up front. • New app icon and refreshed in-app branding. • Extensive stability fixes: several crashes, a freeze after measurement, a duplicate share sheet, a deadlock when re-running a measurement, and the signal generator being interrupted by system sounds. • Accessibility and localization refinements.

This update focuses on professional PDF reports. • Unified section headers and numbering across every report type for a cleaner, more consistent layout. • Redesigned table of contents with precise visual alignment. • Report-integrity hash and QR code on SPL and file-analysis reports, so results are verifiable and traceable. • Many accuracy and wording refinements across SPL, RT60, RTA, and file-analysis reports: clearer event/transient figures, stronger uncalibrated-state disclaimers, and consistent labels. • New app icon and refreshed in-app branding. • SPL export fixes: resolved a duplicate share sheet and corrected sheet timing. • Localization and stability refinements.

Redesigned PDF reports: a unified new cover, automatic table of contents, and section numbering, plus pagination fixes across measurement report types. Smoother, more stable switching between measurement modules — the audio engine is optimized, resolving several switching freezes and crashes. SPL stability: fixed an occasional crash when measuring again after exporting a report, recovery after phone-call interruptions, and an unresponsive stop button. Various localization refinements and stability fixes.

Electroacoustic improvements: more accurate stepped-sine duration estimates. Directivity polar plot: angle labels now rotate with data; added graphical over-range markers. Real-time IMD: corrected SNR calculation, smoother curve consistency, and export timeline calibration for sample rate. Improved real-time IMD measurement performance and stability. Various localization and stability fixes.

Major RTA spectrum analyzer update: delayed spectrum review, customizable waterfall and spectrogram views, measurement presets, and multi-format export (PDF/CSV/JSON). Added feedback (howl) detection sensitivity control. Corrected calibration of the real-time spectrum, frequency weighting, and octave bands; some spectrum readings and noise-curve (NR/NC/RC/PNC) ratings may be lower than in previous versions. Several stability fixes, including a landscape display crash.

Free history now supports up to 10 entries. Thumbnail storage optimized, reducing footprint by about 80%. Multiple stability and performance fixes.

New app icon. Toolbox streamlined to 8 professional tools with a cleaner layout. Translation quality polished across 17 languages. Fixed several stability and performance issues.

v1.82 aligns in-app permission gating with our App Store description for full consistency: measurement functions themselves (real-time display, analysis, history) remain completely free; report export across 16 measurement modules (SPL/RT60/STIPA/THD/IMD/Transfer Function/Impedance/Directivity, etc.) is now a Pro membership benefit with a 7-day free trial; new privacy option (Settings → Advanced) lets you remove location and device info from exports.
