I’m looking for a VST that can show me the spectrogram immediately when playing a song, in the host…
And that can show it as good as foobar2000:
All I have found until now show it up real crappy… 
(would be nice if it was default in renoise too…)
I can recommend NuGen Visualizer
+1 for Nugen visualizer
pretty low quality if you ask me. not reliable at all.
well then,let us know if and when you find a better one 
this should be natively in renoise… oh wait. 
heaven on earth, thanks so so much!
i like both the spectrogram, spectrum and osc in foobar!
