This app cleverly uses your sound card to display an oscilloscope and spectrum analyzer for examining music, speech, or circuit output, but it doesn't have much in the way of user instruction. Zelscope's plain display mimics the look of hardware oscilloscopes. If you feel comfortable around those dials and sliders, you'll be right at home with this app. The short FAQ will not teach you how to operate this app.
Zelscope accurately tracks your sound card as it converts analog sound to digital. Manipulating the basic gain, offset, timebase, and trigger sliders and buttons is very easy. The oscilloscope display is clear and responsive. The app includes easily set features to save data as BMP- or EMF-screen shots, WAV or TXT files, or send info to the printer.
Users with any need to analyze music, speech, or circuit output should give Zelscope a test. The 14-day demo is not hindered in any way, which gives knowledgeable users ample time to test this app.
Converts your PC into a dual-trace storage oscilloscope and spectrum analyzer. The Zelscope application was designed to convert your PC into a dual-trace storage oscilloscope and spectrum analyzer. It uses your computer's sound card as analog-to-digital converter, presenting a real-time waveform or spectrum of the signal which can be music, speech, or output from an electronic circuit. Zelscope features the interface of a traditional oscilloscope, with conventional gain, offset, timebase, and trigger controls. As a real-time spectrum analyzer, Zelscope can display the amplitude and phase components of the spectrum. This version is the first release on CNET Download.com.
