Zelscope is a Windows software that converts your PC into a dual-tracestorage oscilloscope and spectrum analyzer. It uses your computer'ssound card as analog-to-digital converter, presenting a real-timewaveform or spectrum of the signal - which can be music, speech, oroutput from an electronic circuit. Zelscope features the interface of atraditional oscilloscope, with conventional gain, offset, timebase, andtrigger controls. As a real-time spectrum analyzer, Zelscope candisplay the amplitude and phase components of the spectrum.
