Gauss Tesla Meter vs Wavelet Voice Sonogram

Monitor the direction strength of a magnetic field at a particular location. Alerts you when a selected value is reached using visual &/or sound &/or vibration. Synchronizes to a specific signal (x, y, z or magnitude) in 4 different modes: falling edge, rising edge, low state and high state. Records the measurements from 100 to 10000 shots, plot, read and can be sent by Email as a CSV type. Several measure acquirements time base from 0.1 measure/second to 10 measures/second. Display the measurements in µTesla or mGauss unit. Automatic resizing screen. Extremely light weight app. Nota: It is not suitable for iPod which doesn’t have embedded magnetic field sensors. 监测特定位置的磁场的方向强度。 使用视觉和/或声音和/或振动达到所选值时提醒您。 以4种不同的模式同步到特定信号（x，y，z或幅度）：下降沿，上升沿，低状态和高状态。 将测量记录从100到10000记录，绘制，读取，并可以通过电子邮件发送为CSV类型。 几个测量时间基准从0.1测量/秒到10次/秒。 以μTesla或mGauss单位显示测量值。 自动调整大小的屏幕。 翻译为8种不同的语言：英文，法文，西班牙文，意大利文，葡萄牙文，德文，俄文和简体中文。 极轻的应用程序 注意事项：不适用于没有嵌入式磁场传感器的iPod。 监测特定位置的磁场的方向强度。 使用视觉和/或声音和/或振动达到所选值时提醒您。 以4种不同的模式同步到特定信号（x，y，z或幅度）：下降沿，上升沿，低状态和高状态。 将测量记录从100到10000记录，绘制，读取，并可以通过电子邮件发送为CSV类型。 几个测量时间基准从0.1测量/秒到10次/秒。 以μTesla或mGauss单位显示测量值。 自动调整大小的屏幕。 极轻的应用程序 注意事项：不适用于没有嵌入式磁场传感器的iPod。 Surveille la force directionnelle d'un champ magnétique à un endroit particulier. Avertit lorsqu'une valeur sélectionnée est atteinte: Visualisation et / ou son et / ou vibrations. Synchronise les acquisitions avec un signal spécifique (x, y, z ou magnitude) dans 4 modes différents: front descendant, front montant, état bas et état haut. Enregistre les mesures de 100 à 10000 salves, trace, relit et peut envoyer un Email au format CSV. 5 bases de temps sont possibles. De 0,1 mesure / seconde à 10 mesures / seconde. Affichage des mesures en μTesla ou mGauss. Redimensionnement automatique de l’écran. Application extrêmement légère. Nota: Ne convient pas aux iPod car ils sont dépourvus de capteurs de champ magnétique.

"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.
