About

e

This app combines an oscilloscope, FFT analyzer, and signal generator. It allows real-time observation of audio device frequency characteristics and waveform analysis. Features include multiple oscilloscope modes, detailed FFT spectrum analysis, and various signal generation options.

Highlights
  • Oscilloscope with Normal, Trigger, and Single modes
  • FFT analyzer with peak level, frequency, and THD display
  • Signal generator for sine waves, white noise, and sweeps
  • Real-time FFT synchronization sweep mode
  • Screen capture and save functionality
  • Adjustable sensitivity and time span

Three tools (oscilloscope, FFT analyzer (spectrum analyzer), signal generator) are included in the e-scope 3-in-1. Please take a look at this video. Basic functions: http://youtu.be/WPm4Dbz0WAo Automatic measurement add-on: http://youtu.be/K6_stq_t2zQ It can observe the frequency characteristics of audio devices using an FFT analyzer and a signal generator. Observation of frequency characteristics in real time is possible by using the FFT synchronization sweep mode. inputs are acquired via the built-in microphone or headset connector. -Oscilloscope The oscilloscope has three modes. * Normal mode: It is suited to observe music waveforms. * Trigger mode: This mode is suitable for repeated waveforms such as sine wave. You can observe waveforms in stationary condition. * Single mode: This mode is suitable for observing one-time waveform such as impact sound. You can change the sensitivity and time span by pinch out and pinch in. -FFT analyzer It is possible to analyze the frequency spectrum of an input signal. The peak level and the frequency are displayed at the top of the screen. The display can also be used as a simple frequency counter when you enter a single signal. In addition, the THD (Total Harmonic Distortion) value is displayed at the bottom left of the screen. By pressing the resolution button, you can select the frequency resolution free three types. When you press the peak hold button, the maximum value of the signal that you are currently viewing is displayed in a red line. -Signal generator The signal generator can be used to generate a signal of four types: Sine wave of 1Hz to 20kHz, White noise, Linear sweep and Log sweep ranging from 20Hz to 20KHz. When you tap the area that displays the frequency or sweep time range, a picker will appear. Please set the appropriate numbers in it. By using the mode [optimized for FFT], it can automatically change to a frequency with highest FFT accuracy. Please use the feature if you want to accurately measure the THD. While the frequency is displayed, it will be ignored when you enter 0000. During the FFT synchronization sweep mode, when you enter 000 as the display start time for the sweep time display, the FFT synchronization sweep mode will be activated. It will change the frequency at high speed in FFT analysis unit time (less than 0.1 seconds) . It is possible to observe the frequency characteristic in real time in this mode. When you press the Copy button at any mode, you can capture screen and save it to a camera roll.

A new and easy way to practice your musical instrument! (for wind and string instruments player) A metronome, tuner and recorder all set out in the same screen to fit right into your practice session. With the same operations all in one screen, you can quickly go from recording to playback to checking and back to recording. By objectively reviewing your performance and then trying it again, you'll really make progress! ○○○○○ Product Features ○○○○○ A practice app that boosts the efficiency of your musical instrument practice sessions. Most people learning to play a musical instrument practice alone. When you practice with a teacher or with your friends, they can give you advice about your playing and you can identify the problems you need to work on. But when you practice alone, it's much more difficult to see your playing objectively. <That's when "Music Practice" is really invaluable. > You can control the metronome, tuner and recorder all from the same screen, which means that as well as checking your tempo and tuning as you play, you can also directly record your playing. By listening to your recording as soon as you finish playing, you can get an objective impression of your performance. <Straightforward design and layout > A key feature of the app is that the screen is laid out so that it makes practicing more efficient. The features you use in real time are shown larger so you don't hit the wrong button by mistake. And when you tilt your device, the layout automatically flips between horizontal and vertical. So you can set it on your music stand or put it on a table, whatever works best for you. <Customize your design > Because you'll be using it every day, you'll want to get the design just right. There are lots of color variations. Play around until you get the colors just right for you, whether it's your lucky color or just the color that suits your mood today. 【Operating requirements】 iPhone 5, iPhone5s, iPhone5c, iPhone 6, iPhone6 Plus iPod touch (5th generation) ※iOS 7 or later required.
