Zelscope is a Windows software that converts 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.
