Wavelet Voice Sonogram vs Honest Storage Report

"Wavelet Voice Sonogram" is a sound spectrogram app that performs time-frequency analysis of acoustic signals. A spectrogram is a graph displaying the results of a sound frequency spectrum analysis, with time on the horizontal axis, frequency on the vertical axis, and signal strength represented by colors. This app can perform acoustic analysis and display the spectrograms by using three time-frequency analysis methods, Wavelet analysis, Octave Band analysis, and FFT analysis. It can also record sounds from iPhone's built-in microphone. While playing back a recording, you can search for the desired sound and analyze it. "Wavelet Voice Sonogram" makes it easy to analyze the acoustics of speech, instrumental sounds, noise, and more. It can also be used to learn the basics of speech analysis. Features: - Acoustic analysis can be performed using PCM data recorded with the iPhone's built-in microphone. It is possible to analyze 5 seconds of sound data backward from a user-specified point in time. - Three types of acoustic analysis, FFT analysis, octave band analysis and wavelet analysis, can be performed simultaneously. - PCM sound recording and playback is possible up to about 180 seconds, and the audio waveform graph and FFT analysis graph are displayed. While playing back sound, you can search for sound at any point in time. - Zoom in on a specific 10 seconds of PCM data and play back the sound. Used to find a specific sound at the point in time you want to analyze. - The spectrogram analysis result and time axis waveform can be contrasted and played back. Specifications: - Sampling frequency: 48 kHz - PCM recording time: approx. 180 seconds max. - Sound zoom function (10-Sec): Zooms in on any 10 seconds of PCM data and plays back the sound. - 3 types of acoustic analysis function (Analysis): About 5 seconds (Analysis points can be specified using the Time position slider.) -- FFT analysis (FFT): FFT 2048 points -- Octave band analysis (OCT): 1/48 octave band -- Wavelet analysis (DWT): Gabor Wavelet - Sound recording and playback, sound waveform and FFT graph display (Main): PCM graph, 10sec zoom graph, FFT graph. - Time position slider: Points to the cursor position on PCM graph. - Spectrogram display (FFT / OCT / DWT): 5 sec PCM graph and spectrogram analysis graph (vertical axis - time [0 - 5.0 sec], horizontal axis - frequency [100Hz - 8kHz]) - Snapshot (Snap): Save the analysis image in "Photos". Notes: - The acoustic analysis time varies significantly depending on the performance of your iPhone (product generation). It may take about 5 to 20 seconds. - Wireless (Bluetooth) headphones and headsets are not supported. - The first time the app accesses the built-in microphone and Photos after installation, the iOS system will ask you for permission to access them. If you have not enabled this setting, the application will not be able to access them due to iOS system privacy restrictions. Please enable the access permission in 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
