Scope A simple real-time waveform viewer using jack and SDL/OpenGL. This software is one of many, a not-so-featureful soundcard oscilloscope. I wrote this after not being able to find an oscilloscope that 1. worked and 2. had fast screen update. This Scope is pretty bare bones. It has the features I need: - Fast screen update - Real time time/amplitude scale adjust - A "hold" button. - A trigger circuit that works reasonably well with audio The implementation is based on a delay line, with synchronization on the right side of the scope window, positive edge triggered on a lowpass filtered input signal. The delay length can be set arbitrarily long, so it also does "lie detector style" plotting. Manual: try "scope --help". Tue Dec 14 01:51:38 EST 2010
