[projectm-devel] bSpectrum samples not working in wavecode?

[Toby H. <tjw...@gm...>]

I've had a good play around with ProjectM and I've suspected for a
while that the spectrum code isn't working properly.

Here's a simple preset that should display a vertically scrolling
spectrum - but all I'm getting is a horizontal line. I can tell that
beat detection is working because the normal "ProjectM" headphones
preset has scaling headphones and other presets react reasonably to
the audio. This is a simplified version of "raron - simple frequency
spectrum, clouds vertical scroll.milk".
