Ratings & Reviews performance provides an overview of what users think of your app. Here are the key metrics to help you identify how your app is rated by users and how successful is your review management strategy.
5.0This is an analyzer for sound, vibration and magnetic field. Overall we have the following measuring functions. * Sound (Analyzer [FFT / RTA / Spectrogram], Scope, RMS, Signal Generator) * Vibration (Analyzer [FFT], Scope, RMS) * Magnetic field (Scope, RMS) You can pinch (zoom) and pan (scroll) on measurement screens other than RTA and spectrogram, and pan (band selection) on RTA. You can pause by tapping the measurement screen. Since the measurement time is displayed at the time of pause, it is suitable for leaving as evidence. Please take a screenshot of the screen in the system standard way. [Application example] · Record the present situation as quantitative evidence, such as by using recording and use it for the improvement of obstacles. · Use it for science education. · Use it along with the sweep generator to improve the acoustic characteristics of the listening room. Octave RTA (real-time analyzer) has two configurable items, Please use "Settings .app" and change the following as necessary. · Window function · Latency Note: This application has an audio signal oscillation function, and depending on the operation it may generate sound that is harmful to the human body, so please refrain from using things like headphones or headsets. We are not responsible for damage caused by using that equipment. The resolution of the spectrum analysis of speech is about 11 Hz inherent, however, the actual resolution is in the maximum of 3 Hz by interpolation processing. It is not the accuracy that can be used to tune an instrument. Please use the instrument tuning application for that purpose. If you can not find the current point by zooming in or scrolling, you can return to the default state that you can see the whole picture by pressing and holding the measurement screen long. If a remarkable peak near 1 Hz lasts for more than 10 seconds from the beginning of the spectrum analysis results. It will ignore the peak below 1 Hz after 10 seconds. In most cases, this might happen when the accelerometer is dull. For a good result with Octave RTA, we recommend using Window Function and Fast Latency Mode. The adjustable range of the FFT/Scope/RMS gain is from -20 dB to 20 dB. The adjustable range of the SP gain is from 0 dB to 80 dB. The noise reduction threshold is from -80 dB to 0 dB. Allows you to output the data of Sound Spectrum, Sound Spectrogram, and every RMS'. You can use the data files by Files.app on iOS or iTunes File Sharing on Mac. Please note that the output file of Spectrogram is not small not like other data files.
