Strikodo vs Wavelet Voice Sonogram

Strikodo is an App to scan barcodes and to create those. It supports a large number of barcode types and supports a large variety of content types that can be encoded within these barcodes. SCAN BARCODES Scanning barcodes can be done using the built-in camera (torch and the different lenses are supported as well), but you can also scan photos for barcodes. The App supports manual scanning but also automatic scanning to scan a large number of barcodes very fast. Scanned barcodes can be saved within the App, so you can open them anytime later again, edit them, share its content, process its content etc. CREATE BARCODES Creating barcodes is very intuitive, easy and fast. You just pick the type of barcode you want to create, its type of content and then either enter the content or pick it from other sources (like the Contacts, a Map, etc). The barcode is updated "live" while entering or editing the content, so there're no additional steps required to actually get the resulting barcode. The App makes it also possible to create barcodes from within other Apps, without leaving these Apps. All that is required would be to use the "Sharing" feature of these other Apps and then pick "Strikodo" from the Sharesheet. This will directly create a barcode from the shared data (for example any text, a web link, a location from the Maps Apps, a contact from the Contacts App, etc.), which then can be saved within Strikodo and shared again. Depending of the content that is encoded in the barcodes, Strikodo provides a large number of actions you can apply on this content. This can be a simple product search, but also opening a link in a browser, sending E-Mails or messages, making a phone call, show a location on a Map and much more. APPLE WATCH The saved barcodes can be also made available on the Apple Watch, so you can have access to these barcodes even if you don't have the iPhone with you. Even the watch is able to execute certain actions based on the content of the barcodes (like making phone calls, sending messages, show a location on a map) WIDGET The saved barcodes can be also added to the home screen as Widget, so these are accessible immediately without the need to launch the App first (iOS 14 and later). PRIVACY The App respects your privacy. Scanning and creating barcodes happens on the device itself, no data is leaving the device, no internet connection is required. There's no tracking, no ads, no hidden costs, no subscription. DETAILS The following bar code types are support (both for scanning and creating): - QR Code - Aztec Code - Data Matrix - PDF-417 - UPC-A - UPC-E - EAN-8 - EAN-13 - ITF-14 - Interleaved 2/5 - Code 39 - Code 39/43 - Code 93 - Code 128 The following content types are supported (depending of the barcode type): - Sequence of digits (simple Barcodes) - Text - WLAN Hotspots - Web addresses - Contacts (VCard, MeCard) - Events - Phone numbers - SMS numbers - E-Mail adresses - Geo coordinates The following actions can be applied (depending of the barcode content): - Product search - Display a location or address on a map - Save addresses in the Contacts - Save events on the Calendar - Make phone calls - Send Messages/SMS - Send E-Mails - Join WLAN networks - Open Web sites The following sharing options are available (for the barcode graphic and the content): - Share via ShareSheet - Send by E-Mail - Send via Message/SMS - Copy to Clipboard - Save in Album - Print the Barcode

"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.
