The sound may be divided into individual frequencies using a Fast Fourier Transform. The app was built as a utility for use in the development of other Secret Base Design apps. Use Spectral Eye to gain a deeper knowledge of the nature of sound. Most sounds are made up of a variety of sine waves a single whistle, for example, maybe a single wave, whereas a guitar, piano, or the human voice may have multiple waves. The incoming audio signals are analyzed by Spectral Eye to obtain the underlying frequencies. iOS is the only operating system that works with it. Secret Base Design's Spectral Eye is a free oscilloscope plugin. It is available for both PC and Mac operating systems. Finally, once you've customized the tool according to your preference, you can store your preset to use later. The plugin also comes with a strong Channel Mode that lets you monitor your Left/Right, Mid, and Side channels independently. The global meter view on the right side of the interface can be used as a classic level indicator or in time graph mode. The primary waveform window provides controls for zooming in and out, positioning the view, and normalizing the display such that the waveform fills the entire vertical area. The controls themselves appear to be simple at first glance, yet they conceal some quite complex capabilities. Tooltips are available in every element of the interface, and they explain all of the control options in detail. It offers a clean, professional-looking User Interface with a premium feel, and it's resizable. MOscilloscope is included in the MFreeFXBundle for free. Both PC and Mac versions of the S(M)exoscope are available for download. The tool can determine waveform amplitude, duration, and frequency based on where you set a marker on the display. S(M)exoscope also contains an excellent waveform analysis tool in addition to these features. There are four more option buttons at the bottom of the control panel: Sync Redraw, which adjusts how frequently the display refreshes, Freeze, which freezes the display, DC-Kill, which compensates for DC offset, and Channel, which toggles between the right and left audio channels.

The default setting is free mode, which means no re-triggering. The internal trigger speed control knob determines how often the display is reset in internal mode. Each time a waveform peak passes over or below the level selected by the retrigger threshold knob, the display is retriggered in the Rising and Falling modes. The display mode button allows you to choose between four alternatives retrigger modes (Rising, Falling, Internal, and Free). The display controls, which start at the top, allow you to change the display time and waveform amplitude. It has a simple, appealing (if you like orange) UI with a wide waveform display area and several intuitive controls on the right side. Smartelectronix's S(M)exoscope is one of the most popular free Oscilloscope VSTs on the market, and it's easy to see.
