to phrase it another way: its the difference between:
a) oh good, a new sample has arrived, now i must plot it
b) excellent, another 1/60th of a second has elapsed, how many
samples are there for me to draw on the screen?
Now, assuming a 60 Hz refresh rate (which is what
I believe my monitor
has),
and a buffer size of 1024 pixels, that would be a throughput of 61440
samples per second. More than the 48000 sampling rate. So it seems that
drawing every sample *is* a reasonable request. But obviously a lower
refresh rate would also satisfy my needs.
drawing all the samples is not the issue. drawing each sample individually
(and the assorted overhead that goes with it) is.
you really don't want to call a graphics toolkit more than $refresh times
per second...
