Added App Store listings in more languages. No changes to the app itself.

A clearer App Store name and search details. No other changes in this update.

3.0: Change Desk Change Desk compares two intact sealed acoustic runs at the same planned position. Rank band-level changes and share a report linked to the exact stored evidence. • Open a commissioning project → Verify → Change Desk. • Choose baseline and later runs at the same planned position. Confirm comparable stimulus level, gain, microphone position and room conditions. • Compare broadband and matching-band changes, then share the frozen evidence references. Both runs must be accepted, nonvoided and seal-valid, with matching input chain, route, sample rate, scale, stimulus and band set. Matching metadata cannot prove matching physical conditions. Differences are not a transfer function, EQ recommendation or proof of improvement.

This update makes the commissioning fieldbook easier to use with larger text. - Job details scroll with each phase, leaving more room for the active workflow. - A phase menu replaces the compact segmented control at accessibility text sizes. - Listener positions, acceptance results, input details, and action rows stack for clearer reading. - Witness-capture and export buttons grow to show their complete labels. - Input-route details can wrap instead of being cut short. - Filled actions use dark labels for clearer contrast. Your existing jobs, witnessed runs, evidence seals, and acceptance criteria remain in the same local archive. - Added Privacy Policy and Support links in Methodology.

Frequency Loom has been rebuilt as a dedicated acoustic commissioning fieldbook. - Create site-specific jobs with work order, operator, witness, installed-system, microphone, interface, channel, and calibration context. - Plan named listener areas and measurement positions with coordinates, microphone heights, notes, and repeat requirements. - Capture live witnessed runs for pink noise, speech-shaped noise, program material, external sweeps, or ambient sound. - Automatically hold short, clipped, unstable, incomplete, route-changing, or sample-rate-changing captures. - Verify project-defined position coverage, listener-area level spread, spectral consistency, repeatability, and optional referenced level targets. - Seal every retained run with SHA-256 and exclude altered or voided evidence from results. - Export a complete JSON evidence package, CSV ledger, or text commissioning report through the system share sheet. - Review the measurement boundary, current technical references, and privacy behavior in the in-app Methodology record. This release gives Frequency Loom one focused purpose: producing a clear, inspectable acoustic commissioning record.

Version 2.1 adds Field Setup, a measurement-readiness workflow for real audio sessions. New in this build: - Field Setup readiness score for calibration, external mic, quiet baseline, mounting, FFT size, and export planning. - Offline Reference Pack with six bundled 48 kHz WAV test signals for playback-path, room, and spectrum checks. - Profile-specific recommended chains for studio tuning, live-venue checks, noise logs, and vocal range work. - Copyable session brief for notes, reports, or client handoff. - In-app source links and clearer reference-tool limits for phone-based SPL and noise-dose readings. - Safer Noise Log and Hearing Sweep wording to clarify the app is not a certified compliance meter or clinical hearing device. - Fresh App Store screenshots showing the current RTA, SPL, Field Setup, Reference Pack, and tools screens.

This update sharpens the interface: the iPad layout now uses a centered, comfortable reading width instead of stretching edge to edge, plus small display fixes. iPhone is unchanged; still fully on-device.

Frequency Loom 2.0 — five new pro measurement tools, still 100% offline. • THD / Distortion Meter: plays an internal test tone and reports THD, THD+N, SINAD, and ENOB with a harmonic breakdown and CSV export. • Dynamics / Crest Factor: live peak vs RMS in dB with a session aggregate and a reference rail. • Room Mode Calculator: enter L/W/H and see axial fundamentals, mode pile-ups and gaps, and a ratio-quality score. • Polarity Checker: emits a positive-leading pulse and tells you in-polarity vs inverted. • Delay / Distance Finder: a click plus cross-correlation gives lag, distance, and confidence. All DSP runs on-device with synthetic-signal-verified math. No account, no network — your audio never leaves the device.

Version 1.2 - Multiband RT60 per octave band. New in 1.2: - Multiband RT60: after any impulse capture, tap "View Multiband RT60" to see T20 reverberation time computed independently for each of 7 octave bands (63 Hz through 4 kHz). Uses IIR biquad bandpass filtering + Schroeder backward integration per band - the same method used by Room EQ Wizard and professional acoustic software. Tap any bar to see its full Schroeder decay curve. Results are compared against EBU R 68 / ISO 3382-1 control-room targets with pass/fail indication per band. All previous tools (from 1.1): - Real-time spectrum analyzer with 1/1 through 1/24 octave resolution and NC curve overlay - A / C / Z weighted SPL meter with Slow / Fast / Impulse integration and LEQ - Scrolling spectrogram (magma colormap, adjustable FFT) - Chromatic tuner with YIN pitch detection and cents readout - LUFS loudness metering (momentary / short-term / integrated, ITU-R BS.1770) - RT60 room reverberation (Schroeder integration, T20 method) - Tone generator (sine, log sweep, pink / white / brown noise, impulse) - Standing-wave heatmap - 12 listening positions - Audiogram hearing sweep, Crossover designer, Phantom 48V tester - Hum ID, Time Align, Vocal Warmup, OSHA Dosimeter with CSV export - Room History, Room EQ Advisor with treatment recommendations - PDF export from the RTA screen Real DSP throughout. No tracking. No account. Microphone only.

Frequency Loom 1.1 adds an NC (Noise Criterion) curve overlay on the spectrum analyzer with a live NC rating, PDF export of an octave-band report, a Room Measurement History with trend chart and per-measurement treatment notes, and a Room EQ Advisor (pick a room type for RT60 and NC targets plus ranked treatment recommendations). Real DSP throughout — microphone only, no account, no tracking.
