Frequency Sound Generator App 对比 Sonic Tools SVM 的使用情况和统计数据

Frequency Sound Generator is a very simply Frequency Generator. It can provide sound frequencies in range from 1Hz to 25,000Hz. To use Frequency Generator, you could swipe your finger up and down to raise or lower the frequency of the tones. The user interface is very simple and clear. You could adjust the frequency up or down exactly in 1Hz with arrow button, and directly check the frequency by professional wave visualization. The human can hear from 20Hz to 20,000HZ, and you can use Frequency Generator to test your hearing. Usage scenarias: 1. Use Frequency Generator to annoy dogs, cats or people. 2. Use this app as dog whistle to train your dog or other pets. 3. Stop your neighbour’s dog from barking by adjusting the sound frequency until it works. 4. Use this app to tease your classmates or friends as a prank tool. 5. Mosquito repellent. Frequency Generator is easy to allow you to generate tones range from 0Hz to Ultrasonic 25kHz frequency.

Sonic Tools SVM

This is an analyzer for sound, vibration and magnetic field. As the source code of this is widely published as an open source software on GitHub, you can make custom version of this. We welcome the users who want us to make customized version of this app. * 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. 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. 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.
