Sound Level Analyzer PRO vs Honest Storage Report

"Sound Level Analyzer PRO" is an integrated sound measurement app featuring a sound level meter and powerful acoustic analysis tools. It is available for a wide variety of applications, such as measuring ambient noise in neighborhoods, testing audio systems, checking interior noise in vehicles, checking sound at live events, and much more. Its advanced sound analysis capabilities allow you to perform real-time frequency spectrum analysis, time-varying level measurement, and in-depth statistical analysis of sound levels. It can also be used to analyze the multifaceted characteristics and trends in the occurrence frequency of any sound source. # Measurement functions Main (Leq): Sound level measurement in real-time. - Sound level measurement (dB): Leq (equivalent sound level), Min (minimum value), Max (maximum value), Avg (time-averaged equivalent sound level) - Frequency weighting correction characteristics: A (general sound level measurement with auditory correction), C (sound level measurement with almost flatter correction than A correction, e.g. peak evaluation at high volume), Z (flat characteristics without auditory correction, physical sound level measurement) - Time weighting characteristics: Fast=0.125 sec, Slow=1.0 sec Power Spectrum (P.S.): View of frequency spectrum analysis in real-time. - Spectrum analyzer function: FFT analysis, 1/3-octave band response analysis. - FFT frequency range settings: 100Hz - 20kHz (FFT All) / 100Hz - 3kHz / 3kHz - 6kHz - Measured value display function in 1/3 oct band response analysis. (OctVal) - Power spectrum display function at the occurrence time of maximum level. (Display Max) Time Course (T.C.): View of time-history of the sound level. (Graphical representation after measuring completion.) - Time-domain fluctuation level display function: up to 8 hours linked on a timer. Statistical Analysis (S.A.): Statistical analysis of sound level at A-weighting and Fast. (Analysis display after measuring completion.) - Histogram: Displays all detected sound level distribution as a percentage. - Percentile Level (LN:dB): Display the levels of L05 / L10 / L50 / L90 / L95 on the percentile level graph. # Control functions - Calibration function: level correction value setting, -20 to +20dB - Measurement timer function: 1 minute / 5 minutes / 10 minutes / 15 minutes / 20 minutes / 30 minutes / 1 - 8 hours (1 hour unit) - Snapshot: Save measurement display with time stamp to Photos. # Examples of usage scenes: - Measure the noise situation in the workplace. - Examine the frequency component and time variation of noise target. - Check the sound level and background noise level during music performance. - To know the sound volume of snoring at sleep. - Measure the quiet characteristics of electric products for the judgment of purchase. - To know the noise level of the car. Also, as a purchase consideration material for automobiles, measure the in-car noise level at the test drive and compare it. - To know the noise situation in my home. Also, when buying a house, knowing the noise situation of the surrounding environment. # Example of the noise level situation: - 130dB: Engine sound of Airplane - 110dB: Horn of Car - 100dB: Noise of passing train - 90dB: In loud factory - 80dB: In the train, Vacuum cleaner - 70dB: Noisy office, Noisy Street - 60dB: Quiet Car, Normal conversation - 50dB: Quiet office - 40dB: In the library, Quiet residential area - 30dB: Outskirts of midnight, Whisper - 20dB: Sounds of rubbing leaves # Note: At the time of the first access to Microphone and Photos after installing the app, you will be asked authorization to access them by the iOS system. If you have not enabled this setting, the app cannot access them by privacy restrictions of the iOS system. Please enable the access permission on the iOS setting, "Settings > Privacy & Security > Photos or Microphone". Please visit our iOS App support page for more information on this app.

Honest Storage Report shows where your iPhone's capacity actually went — in one read-only report. No scare tactics, no fake cleaning, no deletion. Just facts and numbers. ■ One honest donut chart Your device's total capacity split into six parts: photos, videos, screenshots, system (purgeable caches), other, and free space. Photo library sizes are totalled item by item, entirely on your device. The chart's proportions always match the numbers shown. ■ Findings that state facts only "Videos take up 34% (22.0 GB) of your storage." Every finding is a plain statement backed by a measured number — never "DANGER!" or "ACT NOW!". ■ A big-file list with real priorities Items are scored by size × age × type, so a 2.4 GB video from two years ago outranks yesterday's snapshot. And you can see how much space you would free before you touch anything. ■ This app never deletes There is no delete function — the app is read-only. Deletion stays in the Photos app you already know, and we tell you upfront that deleted items remain in "Recently Deleted" for up to 30 days, so free space does not grow immediately. ■ Track your free space over time Each scan records your free space, so you can watch the trend — "2.5 GB more free than last month" — and look back through your scan history anytime. ■ Honest about its limits - iOS does not let third-party apps read per-app storage breakdowns. For the exact list, check Settings > General > iPhone Storage — we say so right on screen. - Sizes are displayed using 1 GB = 1,073,741,824 bytes (binary), so numbers may differ slightly from the iOS Settings app. - All figures are approximate reference values. This app does not claim to make your iPhone faster. ■ Your data stays on your device All measuring and reporting happens on your device. Your photo library information and scan results are never uploaded. No account required. [Ads and purchase] Every feature is available to use. A banner ad is shown at the bottom of the screen; a one-time "Remove Ads" purchase hides the banner (no subscription, no auto-renewal). Showing ads requires a network connection, but your photo and scan data is never sent. Privacy policy: https://honki.ai/storage-shindan/privacy.html
