After my search for a realtime waveform viewer a while ago didn't quite
yield the result I was looking for, I decided to write one myself.
So here's the first release of jack_oscrolloscope (thanks Dave Robillard
for inventing the name):
http://das.nasophon.de/jack_oscrolloscope/
I hope someone finds this useful. Feedback is appreciated, please let me
know if you encounter any problems.
Cheers,
Dominic
