Bluetooth Info vs Wavelet Voice Sonogram

Everything you want to know about your BLUETOOTH PAN but were afraid to ask. Bluetooth Info is a small and useful utility that lets you see detailed information about current Bluetooth Personal Area Network (PAN) connection from max. speed to supported Bluetooth profiles and more. BLUETOOTH CONNECTION INFO • Detect Bluetooth protocols and standards supported by your device: Classic, High Speed (HS), Low Energy (LE) or Bluetooth Smart. • Detect Bluetooth profiles and versions supported by your device: • Advanced Audio Distribution Profile (A2DP). • Audio/Video Remote Control Profile (AVRCP). • Hands-Free Profile (HFP). • Human Interface Device Profile (HID). • Message Access Profile (MAP). • Personal Area Networking Profile (PAN). • Phone Book Access Profile (PBAP). • Detect Bluetooth tethering options: cellular internet connection sharing options via Bluetooth to other iOS devices. • Detect supported Bluetooth power class, max. ranges. • Detect device supported Bluetooth frequencies and channels with radio interference informations. • Show Bluetooth PAN traffic counters: upload, download, errors, quality of service (QoS) categories. • Detect max. physical Bluetooth speeds in the supported Bluetooth standards. • Show Bluetooth PAN network interface IP address, ISP name, autonomous system name, whois, ping, regional internet registry info. • Low-level informations about the Bluetooth PAN interface, technical parameters, flags. INTERNET INFO • Show default gateways, IP addresses, networks. • Show DNS servers, search domain names, local MAC addresses, host name resolve. • Depth external address analysis: ISP name, autonomous system name, whois, ping, regional internet registry info. • Full offline MAC vendor database. DEVICE INFO • Detect device type and model. • Detect processor type. • Detect memory size. • Detect storage size. • Detect firmware name, version. • Detect last reboot time. REACH UI FEATURES • Info menu with feedback and privacy settings • Use the camera icon (upper-right corner) to create and print/send/share a screenshot from the entire page. • Pull down with your finger to refresh the informations. • Long press on a cell to copy/print/send/open as/share the cell value. • Shake your device to refresh the informations.

"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.
