QOscC - a software osciloscope

QOscC is a highly flexible and configurable software Oscilloscope with a large number of features. This includes support for any number of audio devices (ALSA, OSS, JACK and a number of Serial Multimeters), each with any number of channels that the hardware supports. Each scope display can be configured individually to different display types and variants. e.g. you can chose from standard y-t mode (as on an usual oscilloscope), xy mode (e.g. for measuring the phase shift between two signals) of the FFT mode (to view a spectrum plot of the signal).
