[QUOTE="egonspengleruk, post: 52494, member: 13482"] Im after software to make a video file of a scope like display. We have already got the audio sussed as we have to output two different streams on each audio channel. And yeah, one of the channels will go beep beep :) And audio scopes are easy to write....all you do is read the output of an ADC and add it onto a rotating waveform buffer. I cant use a soundcard scope as my audio file is too low in freq to be handled by soundcards....we are talking around 1Hz here for a heartbeat (we get around this by FM modulating it....outputting it from the soundcard....and then demodulate it in hardware and feed it into my ECG circuit) Egon [/QUOTE]
