xoscope is a digital oscilloscope using input from a sound card or
EsounD and/or a ProbeScope/osziFOX and will soon support Bitscope
hardware. Includes 8 signal displays, variable time scale, math,
memory, measurements, and file save/load.
Xoscope works fine on my old laptop with Celeron M 430, 1GB Ram, Debian 7: I get about 10FPS. Does not display the voltage level of the signal, but still very useful to debug low-frequency Arduino projects.
Very useful. Thanks.
Great program to use your soundcard as an oscilloscope up to the software threshold of 44100 Hz!
