This is a home-grown visualization, with a couple lines of code copied
|
|
||||||
from synaesthesia. It draws the waveform in the bitmap, then fades out
|
|
||||||
the entire bitmap so older waveforms disappear. It looks OK, but it's
|
|
||||||
grayscale so far (haven't solved the cmap problems, note all the commented
|
|
||||||
out code). I'm going to try to make a much better version as time goes
|
|
||||||
on.
