Hey all,

I've been writing a scope the last while, and I'm intrested in how other
people have approached plotting the data.
Currently I'm taking every 50th sample, and drawing a line from the
previous sample to there, and so on. Not particulary neat.
So is there a resample, or smoothing of the samples, or how does one plot a
"smooth" waveform like Ardour / QTractor?

My other question is about RMS, is calculating it in its literal sense
best? Or perhaps only taking every 5th sample?
Resampling the signal from 44.1 or 48k to say 11025? I'm not really sure
which way to go.

Cheers, -Harry
