Thanks, Andrew. I’ve definitely seen screenshots of 3D waterfalls from Spike, is that not a thing anymore?
(See, for example, Jason Glass’s screenshot and video capture at the top of http://www.plsystem.com/pl_spectrum-page.htm – I know you can basically see the same wiggly modulation in a 2D spectrogram, but it’s a lot easier to visualize what it’s doing through time in that 3D graph, in my opinion. Might just be the way my brain is wired, though…)
